用python统计代码行(包括空行和注释)

import osimport stringpath = "/Users/U/workspace/python learning/show-me-the-code/0007/test/"dir = os.listdir(path)def count(file):    total = 0 #总行数    countPound = 0 #注释行数    countBlank = 0 #空行数    line = open(file,'r',encoding='utf-8') #打开文件，因为注释有中文所以使用utf-8编码打开    for li in line.readlines(): #readlines()一次性读完整个文件        total += 1        if not li.split(): #判断是否为空行            countBlank +=1        li.strip()        if li.startswith('#'):            countPound += 1    print(file)    print("countBlank:%d" % countBlank)    print("countPound:%d" % countPound)    print("total:%d" % total)for file in dir:    count(path + file)
