有个目录，里面是你自己写过的程序，统计一下你写过多少行代码。包括空行和注释，但是要分别列出来。

代码

参照网络上代码

# coding: utf-8

import os

import re

# 代码所在目录

FILE_PATH = 'TestDir'

def count_line(file):

    note_line = 0  # 注释行数

    blank_line = 0  # 空行

    with open(file, 'r', encoding='utf-8') as f:

        lines = f.readlines()

        total_line = len(lines)  # 代码总行数

        line_index = 0

        # 遍历每一行

        while line_index < total_line:

            line = lines[line_index]

            # 检查是否为注释

            if line.startswith("#"):

                note_line += 1

            elif re.match(r"\s*'''", line) is not None:

                note_line += 1

                while re.match(".*'''$", line) is None:

                    line = lines[line_index]

                    note_line += 1

                    line_index += 1

            # 检查是否为空行

            elif line == "\n":

                blank_line += 1

            line_index += 1

    print("====================================================")

    print("  在文件%s中：" % file)

    print("----------------------------------------------------")

    print("代码总行数：", total_line)

    print("注释行数：", note_line, "占%0.2f%%" % (note_line * 100 / total_line))

    print("空行数：  ", blank_line, "占%0.2f%%" % (blank_line * 100 / total_line))

    return [total_line, note_line, blank_line]

def run(file_path):

    # 切换到code所在目录

    os.chdir(file_path)

    # 遍历该目录下的py文件

    total_lines = 0

    total_note_lines = 0

    total_blank_lines = 0

    for i in os.listdir(os.getcwd()):

        if os.path.splitext(i)[1] == '.py':

            line = count_line(i)

            total_lines = total_lines + line[0]

            total_note_lines = total_note_lines + line[1]

            total_blank_lines = total_blank_lines + line[2]

    print("==================================================")

    print("总代码行数：", total_lines)

    print("总注释行数：", total_note_lines, "占%0.2f%%" % (total_note_lines * 100 / total_lines))

    print("总空行数：  ", total_blank_lines, "占%0.2f%%" % (total_blank_lines * 100 / total_lines))

if __name__ == '__main__':

    run(FILE_PATH)
