Python Little Practice---Import OS module to do a statistical folder size function

Import OS

def getdirsize (Dirpath):

#设置一个用于累加大小的变量
Total = 0

#获取文件夹中所有文件和文件夹
Allnames = Os.listdir (Dirpath)
#遍历所有文件和文件夹, and add up their size
For I in Allnames:
#遍历同时组合完整路径
FullPath = Os.path.join (dirpath,i)

#判断是文件还是文件夹
If Os.path.isfile (FullPath):
#print (FullPath, '---file ')
#获取文件大小
Total + = Os.path.getsize (FullPath)

Elif Os.path.isdir (FullPath):
#print (FullPath, '---directory ')
#获取文件夹大小
Total + = Getdirsize (FullPath)

Else
#print (fullpath, '---link ')
# Get link size
Total + = Os.path.getsize (FullPath)

#返回总大小
Return Total

#调用函数
result = Getdirsize ('/etc/acpi ') #要统计的文件夹
Print (Result)
