代码统计工具-python版本

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）
