Practice - 5 Tasks

1fill in blank

easy

Complete the code to create an empty __init__.py file that makes a folder a package.

Python

# Create an empty file named [1] in your folder

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

💡 Hint

Common Mistakes

Naming the file without underscores like 'init.py'.

Using a different file name like 'package.py'.

The file named __init__.py tells Python that the folder is a package.

2fill in blank

medium

💡 Hint

Common Mistakes

Using 'from' instead of 'import' in this position.

Using 'as' or 'with' which are incorrect here.

Use import to bring a module from a package into your code.

3fill in blank

hard

Fix the error in the __init__.py file to expose a function from a submodule.

Python

# __init__.py
from .submodule [1] my_function

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

Bfrom

Cas

Ddef

💡 Hint

Common Mistakes

Using 'from' instead of 'import' after the dot.

Trying to define the function instead of importing it.

Use import to expose my_function from the submodule in the package.

4fill in blank

hard

Fill both blanks to create a dictionary comprehension in __init__.py that maps module names to their lengths.

Python

module_lengths = {name: len(name) for name in [1] if len(name) [2] 5}

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

A['mod1', 'mod2', 'longmodule']

Brange(5)

C>

D<

💡 Hint

Common Mistakes

Using range(5) instead of a list of module names.

Using '<' instead of '>' for the length condition.

This comprehension creates a dictionary for module names longer than 5 characters.

5fill in blank

hard

Fill all three blanks to create a dictionary in __init__.py that maps uppercase module names to their lengths if length is less than 10.

Python

module_info = [1]: [2] for [3] in ['modA', 'moduleB', 'modC'] if len([3]) < 10}

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

Aname.upper()

Blen(name)

Cname

Dmod

💡 Hint

Common Mistakes

Using 'mod' instead of the variable name.

Mixing variable names in keys and values.

This dictionary comprehension maps uppercase module names to their lengths for names shorter than 10 characters.
