Common Mistakes

Importing the wrong module that doesn't provide math functions.

Forgetting to import any module and trying to use math functions directly.

The math module provides functions for mathematical operations, so importing it allows you to use those functions easily.

Common Mistakes

Importing a function that doesn't generate integers.

Using the module name instead of the function name in the import.

The randint function generates a random integer between two numbers. Importing it directly lets you use it without the module prefix.

Common Mistakes

Importing a module that does not have the name attribute.

Forgetting to import the module before using it.

The os module provides the name attribute used here. Importing os fixes the error.

Fill both blanks to create a list of squares using the range function and a standard library feature.

Python

squares = [x[1]2 for x in [2](1, 6)]

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

B*

Crange

💡 Hint

Common Mistakes

Using multiplication instead of exponentiation for squares.

Using a wrong function instead of range.

The ** operator is used for exponentiation (power), and range generates numbers from 1 to 5. Together, they create squares of numbers.

5fill in blank

Fill both blanks to create a dictionary of word lengths for words longer than 3 characters.

Python

lengths = {word: {BLANK_2}} for [2] in words if len({{BLANK_3}}) > 3

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

💡 Hint

Common Mistakes

Not starting the dictionary comprehension with a curly brace.

Using the wrong variable name in the comprehension.

Mixing up keys and values.

The dictionary comprehension starts with {, uses the word as the key, and its length as the value. The variable word is used to iterate over words.
