💡 Hint

Common Mistakes

Using mkdir instead of listdir does not list files.

Using remove deletes files instead of getting size.

getsize gets the size of a file, and listdir lists all files in the folder. Together, they create a dictionary of file sizes.

5fill in blank

hard

Fill all three blanks to filter files larger than 1000 bytes and create a dictionary with their names and sizes.

Intro to Computing

import os
large_files = {file: os.path.[1](os.path.join('Documents', file)) for file in os.[2]('Documents') if os.path.getsize(os.path.join('Documents', file)) [3] 1000}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using '<' filters smaller files instead of larger.

Using mkdir instead of listdir does not list files.

getsize gets the file size, listdir lists files, and > filters files larger than 1000 bytes.
