为了掌握好python这把利器,现在准备将语法基础夯实
1. continue语句
#!/usr/bin/python # -*- coding: UTF-8 -*- n=100 while n > 0: n-=1 if n % 2 == 0: continue print (n)
# n-=1 不可以放在这里,一旦遇到continue,while就进入下一次循环而i值却未递增
2.number
[zheng@localhost python]$ cat day01_number_01.py #!/usr/bin/python # -*- coding: UTF-8 -*- import math ''' 改变Number数据类型,将重新分配存储空间 ''' print "abs(-18):",abs(-18) print "math.ceil(-4.1):",math.ceil(-4.1) # cmp only used in python 2.x print "cmp(80,100):",cmp(80,100) print "math.exp(100.12):",math.exp(100.12) print "math.fabs(-5):",math.fabs(-5) print "math.floor(-5.1):",math.floor(-5.1) print "math.log(e):",math.log(math.e) print "math.log(100,10):",math.log(100,10) print "math.log10(100):",math.log10(100) print "max(1,2,6,3.5,8):",max(1,2,6,3.5,8) print "math.modf(100.72):",math.modf(100.72) print "math.pow(100,2):",math.pow(100,2)
