python 统计当前文件夹的大小

使用 os.path.getsize() 返回文件大小，以字节为单位

# -*- coding: utf-8 -*-
import os
import sys

def get_subfile_size(path):
    """ show all subfile size """
    file_info = []
    all_file = os.listdir(path)
    for file in all_file:
        f_info = {}
        f_name = os.path.join(path, file)
        f_size = os.path.getsize(f_name)
        f_info[f_name] = f_size
        file_info.append(f_info)
    return file_info

if __name__ == '__main__':
    path = os.getcwd() + "/learnPython"
    file_info = get_subfile_size(path)
    print file_info
