💡 Hint

Common Mistakes

Using random.choice which selects from a sequence, not a range of integers.

The randint(a, b) function returns a random integer N such that a <= N <= b.

💡 Hint

Common Mistakes

Using randint which returns an integer, not an element from a list.

The choice() function returns a random element from a non-empty sequence like a list.

4fill in blank

Fill both blanks to create a list of 5 random integers between 1 and 20.

Python

numbers = [random.[1](1, 20) for [2] in range(5)]

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

💡 Hint

Common Mistakes

Using randrange which excludes the upper bound, or confusing loop variable names.

Use randint to get random integers including both ends. The variable i is a common loop variable name.

5fill in blank

hard

Fill all three blanks to create a dictionary with words as keys and their lengths as values, only for words longer than 3 letters.

Python

lengths = {word: [1] for word in words if len(word) [2] 3 and word.[3]('a')}

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

Alen(word)

Cstartswith

Dendswith

💡 Hint

Common Mistakes

Using wrong comparison operators or string methods like endswith instead of startswith.

This dictionary comprehension maps each word to its length if the word is longer than 3 letters and starts with 'a'.
