第一：函数的定义
使用函数的背景：
现在领导让你把公司加上机器的监控与报警信息做一下统计，防止遗漏监控，连接数据库代码：
def get_host(): 创建数据库连接 通过cursor方法获取游标 通过execute对sql进行操作 关闭游标 def get_item(): 创建数据库连接 通过cursor方法获取游标 通过execute对sql进行操作 关闭游标 def get_tirggers(): 创建数据库连接 通过cursor方法获取游标 通过execute对sql进行操作 关闭游标
完全可以按照上面的方式操作数据库，但是这样写存在两个问题：
1.代码重复过多
2.如果日后要更改操作数据库，比较麻烦
def con_sql(sql): 创建数据库连接 通过cursor方法获取游标 通过execute对sql进行操作 关闭游标 def get_host(host): conn_sql(host) def get_item(item): conn_sql(item) def get_tirggers(triggers): conn_sql(triggers)
这样写可以体现出函数的好处：
1.解决了代码重用的问题
2.保持代码一致性，易维护
3.容易扩展
在此处提下函数式编程和面向过程编程的区别：
- 函数式：将某功能代码封装到函数中，日后便无需重复编写，仅调用函数即可
- 面向对象：对函数进行分类和封装，让开发“更快更好更强...”
函数的定义及各部分详解：
def test(x): ''' :param x:传入参数是干啥的呀 :return: 返回的是啥呀 ''' x+=1 return x test(4) def:定义函数的关键字 test：函数名 （）：括号内可以定义形参 """ """:函数描述(建议写上） x+=1:函数的逻辑程序 return : 定义返回值 test(4) : 函数名（参数）： 调用运行，这里的x可以带参数，也可以不带的
第二：函数的三种定义方式
无参函数定义：
def hello(): print("hello world") #调用也不需要传参 hello() #输出结果： hello world
有参函数定义：
def hello(x,y): print("hello world",x,y) #调用也不需要传参 hello("zzl","cyy") #输出结果： hello world zzl cyy
空函数定义：
def foo(): ''' :return: ''' pass foo()
空函数写不写参数是无所谓的，空函数主要用于开发大的程序的时候定义
空函数的好处是：
1.理清逻辑
2.哪一个模块有灵感就写哪一个模块
3.当你与你同事共同开发的该程序，你同事没有完成，你可以做一个判断，不影响你的工作
第三：函数的返回值
返回0个值---》None
def foo(): return print(foo()) 返回结果： None
返回一个值---》返回的是return后定义的哪一个值
def foo(): return "hello world" print(foo()) 返回结果： hello world
返回多个值---》返回的是一个元组
def foo(): return 1,2 print(foo()) 返回结果： (1, 2)
返回值可以是任何类型
def foo(): return 1,2,[3,4] print(foo()) 返回结果： (1, 2, [3, 4])
第四：函数三种调用方式
作为语句形式的调用
def my_max(x,y): return x if x > y else y #语句形式：用于没有返回值的形式 my_max(1,2)
作为表达式形式的调用
def my_max(x,y): return x if x > y else y #表达式形式 res=my_max(1,2) print(res) 结果： 2
作为参数形式的调用
def my_max(x,y): return x if x > y else y res=my_max(20,my_max(11,18)) print(res) 结果： 20
第五：函数的形参与实参
#形式参数：x，y，形式参数不占用内存空间，只有真正传值得时候才占用内存空间 def foo(x,y): print(x) print(y) #实际参数1,2，实际参数是真正占用内存空间的 foo(1,2) #注：在python中，名字没有任何储值的功能，任何的储值都是绑定一个名字到一个值
def foo(x,y): return x+y #实际参数1,2，实际参数是真正占用内存空间的 foo(1,2) #注：在python中，名字没有任何储值的功能，任何的储值都是绑定一个名字到一个值 #参数的动态性： print(foo(1,2)) #结果：3 print(foo('a','b')) #结果：ab print(foo(1,'a')) #报错了 TypeError: unsupported operand type(s) for +: 'int' and 'str'
怎么解决这样的问题？
有一下三种方式：
第一种：加上帮助信息，这样其他人用函数的时候，就知道怎么去调用了，但是不能真正的对函数做到限定作用 def foo(x,y): ''' :param x:int :param y:int :return:int ''' return x+y print(help(foo)) foo(x, y) :param x:int :param y:int :return:int 第二种： def foo(x,y): if type(x) is int and type(y) is int: #给核心功能附加程序 return x+y print(foo(1,2)) 第三种：更加妖娆： def foo(x:int,y:int)->int: return x+y print(foo.__annotations__) print(foo(1,2)) 结果： {'x': <class 'int'>, 'y': <class 'int'>, 'return': <class 'int'>} 3 综合以上三种方式：用第一种方式，最后在加上异常处理为标志用法，其他两种也可以用，凭自己个人感觉哈
参数的具体使用：
实参应用：
按位置传值：
# 实参： def foo(x,y): print(x) print(y) # 按位置传值 foo(4,5) 结果： 4 5
按关键字传值：
def foo(x,y): print(x) print(y) # 按关键字传值 foo(y=8,x=6) 结果 6 8
注意问题：
1.针对同一个形参，你可以按照位置或者按照关键字传值，但是只能用一种方式，不能给同一个形式参数传值
2.按关键字传值，必须在按位置传值右边
形参具体使用：
位置参数：
def foo(x,y,z): print(x) print(y) print(z) #位置参数：必须传值 foo(1,2,3) 输出结果： 1 2 3
默认参数：
#默认参数 def foo(x,y=6): print(x) print(y) foo(1) foo(1,8) foo(x=1,y=10) 结果: 1 6 1 8 1 10 注意：默认参数可以不传值，但是也可以传值，传值得话，会覆盖默认参数的值，也可以按照关键字的方式传值。 默认参数的用途： 比如：我们部门男人很多 1.变化比较小的定义为默认参数 2.默认参数必须在位置参数和的右边 3.默认参数一定要定义成一个不可变的类型 4.默认参数在定义的时候已经被赋予了一个明确的值了,后期变化对其无效 验证1,2 def registor(user,age,gender='male'): print(user) print(age) print(gender) registor('zzl',18) 结果： zzl 18 male 验证3： def foo(x,l=[]): l.append(x) return l print(foo(1)) print(foo(2)) print(foo(3)) 结果： [1] [1, 2] [1, 2, 3] 他们每一次调用都指向同一块内存地址 验证4: name='lxh' def foo(x,y=name): print(x) print(y) name='xhb' print(foo(1))
默认参数的好处:
1.降低了函数调用的复杂度
2.可用来扩展函数功能
*args可变参数
- *的作用是‘监听’位置参数，*args等待接收的参数必须是安位置来的
- 凡是遇到带*的参数，那么我们就把它看作是位置参数,把它打散了来看
基本形式： def func(name,age,*args): print(name) print(age) print(args) func('cy',18,'student') 输出结果： cy 18 ('student',) 如果要求传入的参数为列表的情况 def func(name,age,*args): print(name) print(age) print(args) func('cy','18',*['student','lawyer']) 结果输出： cy 18 ('student', 'lawyer')
**kwargs关键字参数
基本形式 def foo(x,y,**kwargs): print(x) print(y) print(kwargs) foo(1,l=2,y=3,z=1,c=2) 结果输出： 1 3 {'l': 2, 'z': 1, 'c': 2} 传入的参数为字典 def foo(x,y,z): print(x) print(y) print(z) foo(**{'x':1,'z':3,'y':2}) # foo(x=1,z=3,y=2) 结果输出： 1 2 3 结合*args def foo(x,y,*args,**kwargs): print(x) print(y) print(args) print(kwargs) foo(1,3,*[6,8,9],c=10,l=12) #输出结果： 1 3 (6, 8, 9) {'c': 10, 'l': 12}
总结：以上四种参数的顺序：位置参数，*args，默认参数，**kwargs
第六：局部变量与全局变量
在子程序中定义的变量称为局部变量，在程序的一开始定义的变量称为全局变量。
全局变量作用域是整个程序，局部变量作用域是定义该变量的子程序。
当全局变量与局部变量重名时：在定义局部变量的子程序内，局部变量起作用；在其它地方全局变量起作用。
1 全局变量 2 msg='hello world' 3 4 def foo(): 5 print(msg) 6 7 foo() 8 9 输出结果： 10 hello world 11 12 局部变量 13 def foo(): 14 msg='hello world' 15 print(msg) 16 foo() 17 18 输出结果： 19 hello world 20 21 msg='hello msg' 22 def foo(): 23 msg='hello world' 24 print(msg) 25 foo() 26 print(msg) 27 28 输出结果： 29 hello world 30 hello msg 31 32 msg='hello msg' 33 def foo(): 34 global msg #定义的是全局变量 35 msg='hello world' 36 print(msg) 37 foo() 38 print(msg) 39 40 #输出结果： 41 hello world 42 hello world
第七：函数的递归
在函数内部，可以调用其他函数。如果一个函数在内部调用自己本省，这个函数就叫递归函数。
列举两个递归查询的例子
1 def foo(n): 2 print(n) 3 if int(n/2) == 0: 4 return n 5 return foo(int(n/2)) 6 7 foo(20) 8 9 输出结果： 10 20 11 10 12 5 13 2 14 1 15 16 def fact(n): 17 print(n) 18 if n == 1: 19 return 1 20 return n * fact(n - 1) 21 22 fact(6) 23 输出结果： 24 6 25 5 26 4 27 3 28 2 29 1
1. 必须有一个明确的结束条件
2. 每次进入更深一层递归时，问题规模相比上次递归都应有所减少
3. 递归效率不高，递归层次过多会导致栈溢出（在计算机中，函数调用是通过栈（stack）这种数据结构实现的，每当进入一个函数调用，栈就会加一层栈帧，每当函数返回，栈就会减一层栈帧。由于栈的大小不是无限的，所以，递归调用的次数过多，会导致栈溢出）
栈溢出示例：
def fact(n): print(n) if n == 1: return 1 return n * fact(n - 1) fact(1000) 输出结果： C:Python35python3.5.exe D:/pytnon/python/函数/函数.py 1000 999 998 997 996 995 994 993 992 991 990 989 988 987 986 985 984 983 982 981 980 979 978 977 976 975 974 973 972 971 970 969 968 967 966 965 964 963 962 961 960 959 958 957 956 955 954 953 952 951 950 949 948 947 946 945 944 943 942 941 940 939 938 937 936 935 934 933 932 931 930 929 928 927 926 925 924 923 922 921 920 919 918 917 916 915 914 913 912 911 910 909 908 907 906 905 904 903 902 901 900 899 898 897 896 895 894 893 892 891 890 889 888 887 886 885 884 883 882 881 880 879 878 877 876 875 874 873 872 871 870 869 868 867 866 865 864 863 862 861 860 859 858 857 856 855 854 853 852 851 850 849 848 847 846 845 844 843 842 841 840 839 838 837 836 835 834 833 832 831 830 829 828 827 826 825 824 823 822 821 820 819 818 817 816 815 814 813 812 811 810 809 808 807 806 805 804 803 802 801 800 799 798 797 796 795 794 793 792 791 790 789 788 787 786 785 784 783 782 781 780 779 778 777 776 775 774 773 772 771 770 769 768 767 766 765 764 763 762 761 760 759 758 757 756 755 754 753 752 751 750 749 748 747 746 745 744 743 742 741 740 739 738 737 736 735 734 733 732 731 730 729 728 727 726 725 724 723 722 721 720 719 718 717 716 715 714 713 712 711 710 709 708 707 706 705 704 703 702 701 700 699 698 697 696 695 694 693 692 691 690 689 688 687 686 685 684 683 682 681 680 679 678 677 676 675 674 673 672 671 670 669 668 667 666 665 664 663 662 661 660 659 658 657 656 655 654 653 652 651 650 649 648 647 646 645 644 643 642 641 640 639 638 637 636 635 634 633 632 631 630 629 628 627 626 625 624 623 622 621 620 619 618 617 616 615 614 613 612 611 610 609 608 607 606 605 604 603 602 601 600 599 598 597 596 595 594 593 592 591 590 589 588 587 586 585 584 583 582 581 580 579 578 577 576 575 574 573 572 571 570 569 568 567 566 565 564 563 562 561 560 559 558 557 556 555 554 553 552 551 550 549 548 547 546 545 544 543 542 541 540 539 538 537 536 535 534 533 532 531 530 529 528 527 526 525 524 523 522 521 520 519 518 517 516 515 514 513 512 511 510 509 508 507 506 505 504 503 502 501 500 499 498 497 496 495 494 493 492 491 490 489 488 487 486 485 484 483 482 481 480 479 478 477 476 475 474 473 472 471 470 469 468 467 466 465 464 463 462 461 460 459 458 457 456 455 454 453 452 451 450 449 448 447 446 445 444 443 442 441 440 439 438 437 436 435 434 433 432 431 430 429 428 427 426 425 424 423 422 421 420 419 418 417 416 415 414 413 412 411 410 409 408 407 406 405 404 403 402 401 400 399 398 397 396 395 394 393 392 391 390 389 388 387 386 385 384 383 382 381 380 379 378 377 376 375 374 373 372 371 370 369 368 367 366 365 364 363 362 361 360 359 358 357 356 355 354 353 352 351 350 349 348 347 346 345 344 343 342 341 340 339 338 337 336 335 334 333 332 331 330 329 328 327 326 325 324 323 322 321 320 319 318 317 316 315 314 313 312 311 310 309 308 307 306 305 304 303 302 301 300 299 298 297 296 295 294 293 292 291 290 289 288 287 286 285 284 283 282 281 280 279 278 277 276 275 274 273 272 271 270 269 268 267 266 265 264 263 262 261 260 259 258 257 256 255 254 253 252 251 250 249 248 247 246 245 244 243 242 241 240 239 238 237 236 235 234 233 232 231 230 229 228 227 226 225 224 223 222 221 220 219 218 217 216 215 214 213 212 211 210 209 208 207 206 205 204 203 202 201 200 199 198 197 196 195 194 193 192 191 190 189 188 187 186 185 184 183 182 181 180 179 178 177 176 175 174 173 172 171 170 169 168 167 166 165 164 163 162 161 160 159 158 157 156 155 154 153 152 151 150 149 148 147 146 145 144 143 142 141 140 139 138 137 136 135 134 133 132 131 130 129 128 127 126 125 124 123 122 121 120 119 118 117 116 115 114 113 112 111 110 109 108 107 106 105 104 103 102 101 100 99 98 97 96 95 94 93 92 91 90 89 88 87 86 85 84 83 82 81 80 79 78 77 76 75 74 73 72 71 70 69 68 67 66 65 64 63 62 61 60 59 58 57 56 55 54 53 52 51 50 49 48 47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3Traceback (most recent call last): File "D:/pytnon/python/函数/函数.py", line 219, in <module> fact(1000) File "D:/pytnon/python/函数/函数.py", line 217, in fact return n * fact(n -

怎样解决这样的问题？
解决递归调用栈溢出的方法是通过尾递归优化，尾递归和循环的效果是一样的，所以，把循环看成是一种特殊的尾递归函数也是可以的
尾递归是指，在函数返回的时候，调用自身本身，并且，return语句不能包含表达式。这样，编译器或者解释器就可以把尾递归做优化，使递归本身无论调用多少次，都只占用一个栈帧，不会出现栈溢出的情况 ，后续详解，尾调用与尾递归
第八：嵌套函数
函数的嵌套通俗的理解为函数套函数就ok了
函数嵌套的定义：
1 def func1(): 2 def func2(): 3 print("my name is func2") 4 func2() 5 func1() 6 7 #输出结果： 8 my name is func2
函数嵌套的调用：
def my_max1(x,y): return x if x > y else y def my_max2(a, b, c, d): return my_max1(my_max1(my_max1(a,b),c),d) print(my_max2(100,200,80,120)) 输出结果： 200
#结合嵌套函数再看全局变量，与局部变量 msg='zzl' def func1(): msg='cyy' def func2(): msg='cy' def func3(): print(msg) return func3 return func2 func1()()() 输出结果： cy
第九：函数是第一类对象
在python中所有的名字都没有储值功能
函数是第一类对象指的是：函数可以被当做数据来处理
被引用
def foo(): print("cyy") f1=foo f1() # 输出结果： cyy
可以当做参数
def foo(): print("cyy") def func(msg): print(msg) msg() func(foo) 输出结果： <function foo at 0x00000000020D3E18> cyy
可以当做返回值
def foo(): print("cyy") def func(msg): return msg f=func(foo) print(f) f() 输出结果： <function foo at 0x0000000002423E18> cyy
可以当做容器类型的一个元素
def foo(): print("cyy") func_dic={ 'foo':foo }
num=func_dic['foo']
num()
输出结果： cyy
第十：匿名函数
匿名函数就是不需要显式的指定函数
1.lambda
def calc(n): return n**n print(calc(10)) #换成匿名函数 calc = lambda n:n**n print(calc(10)) # 输出结果： # 10000000000 # 10000000000
2.map结合lambda
l=[3,2,100,999,213,1111,31121,333] print(max(l)) dic={'k1':10,'k2':100,'k3':30} print(max(dic)) print(dic[max(dic,key=lambda k:dic[k])]) 输出结果： 31121 k3 100
总结：
#当然了,map,filter,reduce,可以处理所有数据类型 name_dic=[ {'name':'zzl','age':1000}, {'name':'cyy','age':10000}, {'name':'zl','age':9000}, {'name':'cy','age':18}, ] #利用filter过滤掉1000,10000,9000 def func(x): age_list=[1000,10000,9000] return x['age'] not in age_list res=filter(func,name_dic) for i in res: print(i) res=filter(lambda x:x['age'] == 18,name_dic) for i in res: print(i) #reduce用来计算1到100的和 from functools import reduce print(reduce(lambda x,y:x+y,range(100),100)) print(reduce(lambda x,y:x+y,range(1,101))) #用map来处理字符串列表啊,把列表中所有人都变成success,比方zzl_success name=['zzl','cyy','zl'] res=map(lambda x:x+'_success',name) for i in res: print(i)
输出结果：
{'age': 18, 'name': 'cy'}
{'age': 18, 'name': 'cy'}
5050
5050
zzl_success
cyy_success
zl_success
第十一：高阶函数
满足一下一个特性都可称为高阶函数
把一个函数的内存地址当做一个参数传到另一个函数
函数的返回值是一个函数名
def add(x,y,f): print(f(x)+f(y)) add(-5,9,abs) 输出结果： 14
