💡 Hint

Common Mistakes

Using multiplication (*) instead of exponentiation (**).

Using addition (+) instead of exponentiation.

The ** operator is used to raise a number to a power. Here, x**2 means x squared.

Complete the code to create a list of even numbers from 1 to 10 using list comprehension with a condition.

Python

evens = [x for x in range(1, 11) if x [1] 2 == 0]
print(evens)

💡 Hint

Common Mistakes

Using addition (+) instead of modulus (%).

Using floor division (//) instead of modulus.

The % operator gives the remainder of division. If x % 2 == 0, x is even.

Fix the error in the list comprehension to get numbers greater than 5 from the list.

Python

numbers = [1, 3, 6, 8, 2]
greater_than_five = [n for n in numbers if n [1] 5]
print(greater_than_five)

💡 Hint

Common Mistakes

Using less than (<) instead of greater than (>).

Using equality (==) instead of comparison.

To get numbers greater than 5, use the greater than operator >.

Fill both blanks to create a list of squares of odd numbers from 1 to 10.

Python

odd_squares = [x[1]2 for x in range(1, 11) if x [2] 2 != 0]
print(odd_squares)

💡 Hint

Common Mistakes

Using addition (+) instead of exponentiation.

Using floor division (//) instead of modulus.

Use ** to square the number and % to check if the number is odd by checking remainder not equal to zero.

hard

Fill all three blanks to create a list of uppercase words that have length greater than 3.

Python

words = ['apple', 'bat', 'carrot', 'dog']
result = [[1].upper() for [2] in words if len([3]) > 3]
print(result)

💡 Hint

Common Mistakes

Using different variable names inconsistently.

Applying .upper() to the list instead of the word.

Use the variable word consistently to refer to each item in the list. Apply .upper() to convert to uppercase and check length with len(word) > 3.
