软件著作权统计代码行数

最近在申请软件著作权，其中有要求要统计行数，发现网上的版本都不尽人意，往往只能统计一层，所以我就改进了一下😁，改成了递归调用版本，这样就不需要再手动遍历文件夹了

#coding:utf-8
import os

class StatLines(object):
    total = 0
    def stat_lines(self,path):
        for root, dirs, files in os.walk(path, topdown=False):
            for file in files:
                if file.endswith('.py'):
                    file = os.path.join(root, file)
                    lines = open(file, encoding='utf-8').readlines()
                    count = 0
                    for line in lines:
                        if line == '\n':
                            continue
                        elif line.startswith('#'):
                            continue
                        else:
                            count += 1
                    self.total += count
                    print('%s has %d lines' %(file,count))
            for dir in dirs:
                path = os.path.join(root, dir)
                self.stat_lines(path)
            
        print('total lines is: %d' %self.total)

if __name__ == '__main__':
    sl = StatLines()
    sl.stat_lines('想要统计的文件夹路径')
