（一）自动化安装依赖方式
1、把依赖的文件列表与已安装的列表对比，没有的就安装
2、执行用例之前就安装一遍依赖
3、判断依赖文件内容有没有变化，如果有变化就执行一次安装（推荐这种方式）
4、自动依赖脑图分析：
例如Windows系统，家目录的路径为：用户-->XXX
5、编写程序
参考实例：auto_install.py
# pip itall -r requriments.txt # pip freeze > requirements_local.txt # pip install xxx import hashlib import os user_home = os.environ['USERPROFILE'] if os.environ.get('USERPROFILE') else os.environ.get('HOME') class InstallRequire: # 存放本地缓存的文件 local_file = os.path.join(user_home,'.requirments_cache') require_file = 'requirements.txt' command = 'pip install -r requirements.txt' @property def check_local_file(self): if os.path.exists(self.local_file): return True #静态方法 @staticmethod def read_file(file_name): with open(file_name,encoding='utf-8') as fr: return fr.read() @staticmethod def write_file(file_name,content): with open(file_name,'w',encoding='utf-8') as fr: return fr.write(content) @staticmethod def md5(msg): msg = str(msg) m =hashlib.md5(msg.encode()) return m.hexdigest() def main(self): require_file_md5 = self.md5(self.read_file(self.require_file)) if self.check_local_file: local_file_md5 = self.read_file(self.local_file) if local_file_md5 != require_file_md5: print('依赖文件有变化，开始安装！') os.system(self.command) self.write_file(self.local_file,require_file_md5) print('安装完成!') else: print('依赖文件没有变化，继续执行！') else: print('未发现本地缓存文件，开始安装依赖！') os.system(self.command) self.write_file(self.local_file, require_file_md5) if __name__ == '__main__': ir = InstallRequire() ir.main()
执行截图所示：
（二）多线程和多进程
1、进程和线程的含义
（1）进程：一个程序，它是一组资源的集合；一个进程里面默认是有一个线程的，主线程
（2）线程：最小的执行单位；线程和线程之间是互相独立的；主线程等待子线程执行结束；线程和线程之间，数据是共享的。
（3）一个进程包含多个线程
2、单线程例子：
import threading import time def clean(): print('打扫卫生') time.sleep(2) def wash_clothes(): print('洗衣服') time.sleep(3) def cook(): print('做饭') time.sleep(1) # 单线程的方式 clean() wash_clothes() cook()
3、多线程例一：
import threading import time def clean(): print('打扫卫生') time.sleep(2) def wash_clothes(): print('洗衣服') time.sleep(3) def cook(): print('做饭') time.sleep(1) # 多线程 start_time = time.time() t = threading.Thread(target=clean) t2 = threading.Thread(target=wash_clothes) t3 = threading.Thread(target=cook) t.start() t2.start() t3.start() t.join() t2.join() t3.join() end_time = time.time() print(end_time-start_time) print(threading.activeCount() ) # 获取当前的线程数
4、多线程例二：（Python的多线程是利用不了多核CPU的）
（1）等待多个子线程执行结束，把启动的子线程放到list中，再循环调用t.join
import threading import time import random def export_data(): print(threading.current_thread()) print('export_data') time.sleep(random.randint(1,5)) #1、等待多个子线程执行结束，把启动的子线程放到list中，再循环调用t.join thread_list = [] for i in range(10): t = threading.Thread(target=export_data) thread_list.append(t) t.start() for t in thread_list: t.join() print('数据都导完了')
（2）等待多个子线程执行结束，通过判断当前线程数
import threading import time import random def export_data(): print(threading.current_thread()) print('export_data') time.sleep(random.randint(1,5)) #2、等待多个子线程执行结束，通过判断当前线程数 for i in range(10): t = threading.Thread(target=export_data) t.start() while threading.active_count() !=1: pass print('数据都导完了')
5、函数传参
实例：多线程函数传参.py
import threading import requests import auto_install def down_load_pic(url): print('开始下载',url) r = requests.get(url) file_name = auto_install.InstallRequire.md5(url) + '.jpg' with open(file_name,'wb') as fw: fw.write(r.content) urls = [ 'https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1606147468333&di=20d70afc041d614c95ed4bece923a30f&imgtype=0&src=http%3A%2F%2Fimage.biaobaiju.com%2Fuploads%2F20190624%2F14%2F1561358630-nlyshjVPwq.jpg', 'https://ss1.bdstatic.com/70cFuXSh_Q1YnxGkpoWK1HF6hhy/it/u=2726503334,2969167273&fm=26&gp=0.jpg', 'https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1606147501828&di=53cbd54babc4a99fcfe1f8da6ecee1f5&imgtype=0&src=http%3A%2F%2Fimgsrc.baidu.com%2Fforum%2Fw%3D580%2Fsign%3D1f6bfa4da06eddc426e7b4f309dab6a2%2F7b4a031b0ef41bd5bcf13c5c5cda81cb38db3d48.jpg', 'https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1606147467777&di=2d4404ca7bc33c49c008749a6d4a04c2&imgtype=0&src=http%3A%2F%2Fimg.article.pchome.net%2F00%2F25%2F47%2F87%2Fpic_lib%2Fs960x639%2F004s960x639.jpg' ] for url in urls: t = threading.Thread(target=down_load_pic,args=[url]) t.start() while threading.active_count()!=1: pass print('所有图片下载完成！')
6、线程锁：多个线程同时操作同一个数据的时候，需要加锁和解锁：（线程安全）
import threading count = 0 lock = threading.Lock() def add(): global count for i in range(10000): # # 加锁 # lock.acquire() # count+=1 # #解锁 # lock.release() with lock: count +=1 for i in range(2): t = threading.Thread(target=add) t.start() while threading.active_count() !=1: pass print(count)
7、守护线程：守护主线程，只要主线程结束，不管子线程有没有执行完成，全部都结束。
import threading import time import random def talk(name): print('正在和%s聊天'%name) time.sleep(random.randint(1,5)) print('和%s聊完了'%name) t = threading.Thread(target=talk,args=['Nancy']) # 设成守护线程 t.setDaemon(True) t.start() t = threading.Thread(target=talk,args=['Mick']) # 设成守护线程 t.setDaemon(True) t.start() t = threading.Thread(target=talk,args=['Bob']) # 设成守护线程 t.setDaemon(True) t.start() t = threading.Thread(target=talk,args=['Bill']) # 设成守护线程 t.setDaemon(True) t.start() while threading.active_count() !=1: pass print('退出QQ')
8、队列：异步处理，保证顺序
（1）队列.py
#队列 list：异步化处理 import queue import random import time import threading orders_q = queue.Queue() # 生产者/消费者模式 def producer(): for i in range(100): order_id = random.randint(1,999) print('订单生成，orderid:%s'%order_id) orders_q.put(order_id) time.sleep(1) def consumer(): while True : if orders_q.qsize() >0: order_id = orders_q.get() print('订单落库',order_id) t = threading.Thread(target=producer) t.start() t = threading.Thread(target=consumer) t.start()
（2）队列多个消费者：
import queue import random import time import threading orders_q = queue.Queue() # 生产者/消费者模式 def producer(): for i in range(100): order_id = random.randint(1,999) print('订单生成，orderid:%s'%order_id) orders_q.put(order_id) time.sleep(1) def consumer(): while True : if orders_q.qsize() >0: order_id = orders_q.get() print('consumer1,订单落库',order_id) def consumer2(): while True : if orders_q.qsize() >0: order_id = orders_q.get() print('consumer2,订单落库',order_id) t = threading.Thread(target=producer) t.start() t = threading.Thread(target=consumer) t.start() t = threading.Thread(target=consumer2) t.start()
9、线程池：
（1）需要安装线程池：
pip install threadpool
（2）线程池.py
import threadpool import requests import threading import auto_install import os def down_load_pics(url): print(threading.current_thread()) print('开始下载',url) r = requests.get(url) file_name = auto_install.InstallRequire.md5(url)+'.jpg' with open(os.path.join('imgs',file_name),'wb') as fw: fw.write(r.content) urls = [ 'https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1606147468333&di=20d70afc041d614c95ed4bece923a30f&imgtype=0&src=http%3A%2F%2Fimage.biaobaiju.com%2Fuploads%2F20190624%2F14%2F1561358630-nlyshjVPwq.jpg', 'https://ss1.bdstatic.com/70cFuXSh_Q1YnxGkpoWK1HF6hhy/it/u=2726503334,2969167273&fm=26&gp=0.jpg', 'https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1606147501828&di=53cbd54babc4a99fcfe1f8da6ecee1f5&imgtype=0&src=http%3A%2F%2Fimgsrc.baidu.com%2Fforum%2Fw%3D580%2Fsign%3D1f6bfa4da06eddc426e7b4f309dab6a2%2F7b4a031b0ef41bd5bcf13c5c5cda81cb38db3d48.jpg', 'https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1606147467777&di=2d4404ca7bc33c49c008749a6d4a04c2&imgtype=0&src=http%3A%2F%2Fimg.article.pchome.net%2F00%2F25%2F47%2F87%2Fpic_lib%2Fs960x639%2F004s960x639.jpg', 'https://ss0.bdstatic.com/70cFvHSh_Q1YnxGkpoWK1HF6hhy/it/u=2121278104,33728762&fm=26&gp=0.jpg', 'https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000c=1606323851635&di=113f81718f7c64a36edb0c60908a5bee&imgtype=0&src=http%3A%2F%2Fwww.euro-premium.cn%2Fsites%2Fdefault%2Ffiles%2F2018%2F11%2F2018-11-22-601.jpg', 'https://ss0.bdstatic.com/70cFvHSh_Q1YnxGkpoWK1HF6hhy/it/u=4220879049,1581383431&fm=26&gp=0.jpg', 'https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1606323851632&di=be753a1b6588ca82d7d198e4facc58a8&imgtype=0&src=http%3A%2F%2Fpic4.zhimg.com%2Fv2-3ea59767a18b17cefc2d47544f75cc73_b.jpg', 'https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1606323851618&di=6020618ac70ba8cc4ca5fb1cc95018d8&imgtype=0&src=http%3A%2F%2Fpic5.58cdn.com.cn%2Fp1%2Fbig%2Fn_v1bl2lwkd2dcwvr2gxjeiq_d4473fafff50fcf7.jpg', 'https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1606323851617&di=5b3ceb961409c8761669367ad4e989cd&imgtype=0&src=http%3A%2F%2Fn.sinaimg.cn%2Fsinacn12%2F276%2Fw575h501%2F20180707%2F95e8-hexfcvm1029102.png', 'https://ss1.bdstatic.com/70cFuXSh_Q1YnxGkpoWK1HF6hhy/it/u=2386572285,3431827098&fm=26&gp=0.jpg', 'https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1606324141028&di=25b7667857e706069b7332a4cd056ea6&imgtype=0&src=http%3A%2F%2Fwww.goupuzi.com%2Fnewatt%2FMon_1909%2F1_174217_f7de79ed750c14f.png', 'https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1606324141027&di=4698c9dba49ca37ee3cf317019c75031&imgtype=0&src=http%3A%2F%2Fb-ssl.duitang.com%2Fuploads%2Fitem%2F201807%2F31%2F20180731112006_owdwm.jpg', 'https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1606324141025&di=5603beb7e5b9cc233517b8224494591f&imgtype=0&src=http%3A%2F%2Finews.gtimg.com%2Fnewsapp_bt%2F0%2F10488054738%2F1000.jpg', 'https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1606324141024&di=2ec0d81314a0d9d28b09c3a802033428&imgtype=0&src=http%3A%2F%2Fimg.mp.itc.cn%2Fupload%2F20170331%2F3152b322ec994c648b2187231403d13f_th.jpg', 'https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1606324141023&di=c841e552dcfd7700c35dca775c1f8cf1&imgtype=0&src=http%3A%2F%2Fimage.uczzd.cn%2F1473046732427962250.jpg%3Fid%3D0', 'https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1606324141019&di=0e5c216e09f1ad9158fbf5e38dd256ac&imgtype=0&src=http%3A%2F%2Fspider.ws.126.net%2Fc5638d86b52baf7e3238309b3cc0731b.jpeg' ] pool = threadpool.ThreadPool(5) # 让它给每个线程分配数据 reqs = threadpool.makeRequests(down_load_pics,urls) #[pool.putRequest(req) for req in reqs] # 开始运行起来 for req in reqs: pool.putRequest(req) # 等待子线程执行结束 pool.wait() print('运行完成!')
（3）Python中有个全局解释器锁：GIL
（4）CPU密集型任务：消耗CPU比较多，例如数据的排序，通过运行计算之类的
（5）iOS密集型任务：input/output，例如写文件，读文件，上传下载操作
10、多进程：是可以利用多核CPU的
多进程.py
import multiprocessing # lock = multiprocessing.Lock() import time def make_money(): print('开始挣钱') time.sleep(10) def start_process(): for i in range(5): p = multiprocessing.Process(target=make_money) p.start() print(multiprocessing.active_children()) while len(multiprocessing.active_children()) !=1: pass print('运行结束！') if __name__ == '__main__': start_process()
（三）unittest基本使用
1、单元测试
（1）自己测试自己写的代码
单元测试框架：自动校验结果
unittest
pytest
（2）如何写测试用例
（3）如何查找测试用例：unittest.defaultTestLoader.discover()
# 查找某个目录下的测试用例 test_suite = unittest.defaultTestLoader.discover('cases','test*.py')
注：如果cases在别的其他路径下，而不在当前路径，直接将case文件夹名称改为绝对路径
（4）参数化
需要安装一个模块：
pip install parameterized
实例如下：
# 参数化 @parameterized.parameterized.expand( [ [1,2,3,'参数化第一条'], [-1,2,1,'参数化第二条'], [-1,2,2,'参数化第三条'], ] ) def test_param_add(self,a,b,c,desc): self._testMethodDoc = desc self.desc = desc result = add(a,b) self.assertEqual(c,result,'预期是%s，实际结果是%s'%(c,result))
（5）产生测试报告
实例1：my_function
def write_file(file_name,content): with open(file_name,'w',encoding='utf-8') as fw: fw.write(content) def add(a,b): return a+b if __name__ == '__main__': print(add(1,2)) print(add(-1, 2)) print(add(-1, -2)) print(add(-1.1, -2.0)) print(add(-1.1, 2))
引用模块：HTMLTestRunner.py
""" A TestRunner for use with the Python unit testing framework. It generates a HTML report to show the result at a glance. The simplest way to use this is to invoke its main method. E.g. import unittest import HTMLTestRunner ... define your tests ... if __name__ == '__main__': HTMLTestRunner.main() For more customization options, instantiates a HTMLTestRunner object.

执行结果如下：
2、设置python文件模板（如图是Pycharm：）
（1）设置模板文件
（2）验证设置的Python模板是否生效：
进入画布页面，新建一个Python文件，自动带入设置的模板：
