在网上搜了相关代码统计工具，发现统计python代码的工具貌似还没有出现，遂小试一把自己编写一版python代码统计工具。
语言：python
废话少说上代码

其实代码统计不外乎就是2点

1、扫描当前路径下所有相关文件

2、统计时候区分 空白行、注释行和代码行

同理，举一反三可以写出Javascript代码统计方法：

def stat_js_files(project_path):

     # Get files list.
    py_file_list = list()
    _scan_file_by_type(project_path, '', 'js', py_file_list)

    # Start to statics files line.
    comment_num = 0
    blank_num = 0
    code_num = 0
    for py_file in py_file_list:
        py_file_handle = file(py_file['path'] + '/' + py_file['name'])

        is_comment_start = False
        while True:
            _line = py_file_handle.readline()
            if _line:

                # comment /* line.
                mark_num = _line.count("/*")
                if mark_num:
                    is_comment_start = True
                    comment_num += 1
                    continue

                # comment */ line.
                mark_num = _line.count("*/")
                if mark_num:
                    is_comment_start = False
                    comment_num += 1
                    continue

                # comment # line.
                mark_num = _line.count('//')
                if mark_num:
                    comment_num += 1
                    continue

                # blank line.
                mark_num = _line.count(' ') + _line.count('\n')
                if mark_num == len(_line):
                    blank_num += 1
                    continue

                # Code Line.
                if is_comment_start is False:
                    code_num += 1
                else:
                    comment_num += 1
            else:
                print '%s...OK' % py_file['name']
                break

    total_line = comment_num + blank_num + code_num
    print '****** Result ******'
    print 'Total    : %d' % total_line
    print 'Comment  : %d  %.2f %%' % (comment_num, float(comment_num)*100/float(total_line))
    print 'Blank    : %d  %.2f %%' % (blank_num, float(blank_num)*100/float(total_line))
    print 'Code     : %d  %.2f %%' % (code_num, float(code_num)*100/float(total_line))
    print '********************'

小结：

工具写得比较简单，有些特殊情况没有进行细分，例如：一行既有代码又有注释的时候统一按照注释行统计了（貌似有点小亏）

以上就介绍了代码统计工具-python版本，包括了方面的内容，希望对Javascriptjrs看球网直播吧_低调看直播体育app软件下载_低调看体育直播有兴趣的朋友有所帮助。
