This article mainly introduces the relevant knowledge of "python3 how to view folder size". Xiaobian shows you the operation process through actual cases. The operation method is simple, fast and practical. I hope this article "python3 how to view folder size" can help you solve the problem.

Specific operation method:

1. First, you need to import the os module into the python script for file operations.

import os

2, and then traverse all the contents of the folder by using the os.walk function.

3. After traversing the folder, you can sum all file sizes statistically.

The code example is as follows:

import os

from os.path import join, getsize

def getdirsize(dir):

size = 0

for root, dirs, files in os.walk(dir):

size += sum([getsize(join(root, name)) for name in files])

return size

if __name__ == '__main__':

size = getdirsize(r'D:\yisu')

print('There are %.3f' % (size / 1024 / 1024), 'Mbytes in D:\\yisu')\

Related operations:

Use the os.path.getsize ('file path') method to get the file size.

import os #import os module

os.path.getsize('d:/bin/yisu.txt ') #Get the specified file size
