💡 Hint

Common Mistakes

Using len() which is for length of collections.

Using max() or min() which compare values but don't change sign.

The abs() function returns the absolute value of a number.

2fill in blank

medium

Complete the code to convert the string '123' to an integer using a built-in function.

Python

number = [1]('123')
print(number + 1)

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

Afloat

Bstr

Cint

Dbool

💡 Hint

Common Mistakes

Using str() which keeps it as text.

Using float() which converts to decimal number.

Using bool() which converts to True or False.

The int() function converts a string representing a number into an integer.

3fill in blank

hard

Fix the error in the code by completing the blank with the correct built-in function to get the length of the list.

Python

my_list = [1, 2, 3, 4]
print([1](my_list))

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

Alen

Blength

Csize

Dcount

Attempts:

💡 Hint

Common Mistakes

Using count which is a list method but needs an argument.

Using length or size which are not built-in functions in Python.

The built-in function len() returns the number of items in a list.

4fill in blank

hard

Fill both blanks to create a dictionary with words as keys and their lengths as values, using built-in functions.

Python

words = ['apple', 'bee', 'cat']
lengths = { [1]: [2] for word in words }

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

Aword

Blen(word)

Cword.upper()

Dword.lower()

Attempts:

3 left

💡 Hint

Common Mistakes

Using word.upper() or word.lower() as values instead of lengths.

Using len without parentheses.

The dictionary comprehension uses the word as the key and len(word) as the value.

5fill in blank

hard

Fill all three blanks to create a dictionary with uppercase keys and values that are True if the length is greater than 3.

Python

words = ['dog', 'elephant', 'cat']
result = { [1]: [2] > 3 for [3] in words }

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

Aword.upper()

Blen(word)

Cword

Dword.lower()

Attempts:

3 left

💡 Hint

Common Mistakes

Using word.lower() instead of uppercase for keys.

Using word instead of len(word) for values.

Not using the loop variable word correctly.

The keys are uppercase words, the values check if length is greater than 3, and the loop variable is word.
