Practice - 5 Tasks

1fill in blank

easy

Complete the code to create a folder named 'Documents' to keep files organized.

Intro to Computing

import os
os.[1]('Documents')

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

💡 Hint

Common Mistakes

Using remove instead of mkdir deletes folders.

Using listdir lists files but does not create folders.

The mkdir function creates a new folder. This helps keep files organized by grouping them.

medium

Complete the code to list all files in the 'Documents' folder.

Intro to Computing

import os
files = os.[1]('Documents')
print(files)

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

💡 Hint

Common Mistakes

Using mkdir creates a folder instead of listing files.

Using remove deletes files or folders.

The listdir function lists all files and folders inside the specified folder. This helps you see what is inside 'Documents'.

3fill in blank

hard

Fix the error in the code to move a file named 'notes.txt' into the 'Documents' folder.

Intro to Computing

import os
os.[1]('notes.txt', 'Documents/notes.txt')

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

Acopy

Cmove

Ddelete

💡 Hint

Common Mistakes

Using move causes an error because it's not in os module.

Using delete removes the file instead of moving it.

The rename function can be used to move a file by changing its path. This moves 'notes.txt' into the 'Documents' folder.

4fill in blank

hard

Fill both blanks to create a dictionary that maps file names to their sizes in the 'Documents' folder.

Intro to Computing

import os
sizes = {file: os.path.[1](os.path.join('Documents', file)) for file in os.[2]('Documents')}

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

Clistdir

Dremove

💡 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.
