File system structure in Intro to Computing - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to represent the root directory symbol in a file system path.

Intro to Computing

root_path = "[1]"

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

💡 Hint

Common Mistakes

Using backslash which is common in Windows but not the root symbol in Unix.

Using colon or asterisk which are not directory symbols.

The root directory in most file systems is represented by a forward slash /. This is the starting point of the file system tree.

2fill in blank

medium

Complete the code to join folder names into a file path using the correct separator.

Intro to Computing

file_path = "home" + [1] + "user" + [1] + "documents"

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

💡 Hint

Common Mistakes

Using backslash which is used in Windows paths.

Using colon or pipe which are not valid folder separators.

The forward slash / is used as a folder separator in Unix-like file systems to join folder names into a path.

3fill in blank

hard

Fix the error in the code to correctly represent a file path on Windows.

Intro to Computing

windows_path = "C:[1]Users[1]Public"

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

💡 Hint

Common Mistakes

Using forward slash which is common in Unix but not Windows.

Using colon or pipe which are invalid separators.

Windows file paths use the backslash \ as the folder separator.

4fill in blank

hard

Fill both blanks to create a dictionary comprehension that maps folder names to their depth level if depth is greater than 1.

Intro to Computing

folder_depths = {folder: [1] for folder, depth in folders.items() if depth [2] 1}

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

Adepth

B>

C<

D==

💡 Hint

Common Mistakes

Using the folder name instead of depth as the value.

Using wrong comparison operators like less than or equal.

The comprehension maps each folder to its depth only if the depth is greater than 1.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension that maps uppercase folder names to their depth if depth is less than or equal to 3.

Intro to Computing

filtered_folders = [1]: depth for folder, depth in folders.items() if depth [2] 3 and folder.isupper() == [3]

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

Afolder.upper()

B<=

CTrue

Dfolder.lower()

Attempts:

💡 Hint

Common Mistakes

Using lowercase conversion instead of uppercase.

Using wrong comparison operators.

Checking folder.isupper() against False instead of True.

The comprehension maps the uppercase folder name to its depth if the depth is less than or equal to 3 and the folder name is uppercase.
