python基础 -- os模块

获取指定文件夹的大小：

方法1：使用递归：

import os
def  getTotalSize(path):
    sumSize = 0
    if os.path.isdir(path):
        dirList = os.listdir(path)
        for dir in dirList:
            if os.path.isdir(os.path.join(path, dir)):
                sumSize += getTotalSize(os.path.join(path, dir))
            else:
                sumSize += os.path.getsize(os.path.join(path, dir))
        return sumSize
    elif os.path.isfile(path):
        return os.path.getsize(path)
    else:
        print("not valid path")

方法2： 使用循环列表

import os
def getTotalSizeByXH(path):
    if os.path.isdir(path):
        sumSize = 0
        listdir = [os.path.join(path, dir) for dir in os.listdir(path)]
        print("listdir", listdir)
        while listdir:
            subDir = listdir.pop(-1)
            print("subDir", subDir)
            if os.path.isdir(subDir):
                listdir.extend([os.path.join(subDir, dir) for dir in os.listdir(subDir)])
            else:
                sumSize+=os.path.getsize(subDir)
        return sumSize
    elif os.path.isfile(path):
        return os.path.getsize(path)
    else:
        print("%s, 该路径非法" %path)
