💡 Hint

Common Mistakes

Using '*' instead of '**' will multiply but not raise to power.

Using '+' will add numbers instead of exponentiation.

The ** operator is used to raise a number to the power of another number. Here, 4 squared is 4².

Complete the code to find the remainder when 17 is divided by 5.

Python

remainder = 17 [1] 5

💡 Hint

Common Mistakes

Using '//' gives the quotient, not the remainder.

Using '*' or '+' will not give the remainder.

The % operator gives the remainder of division. 17 % 5 equals 2.

💡 Hint

Common Mistakes

Using '/' returns a float, not an integer.

Using '%' returns the remainder, not the quotient.

The // operator performs integer division, giving the quotient without the remainder. 15 // 4 equals 3.

Fill both blanks to create a dictionary of squares for numbers 1 to 5, but only include squares greater than 10.

Python

squares = {x: x[1]2 for x in range(1, 6) if x[1]2[2]10}
print(squares)

💡 Hint

Common Mistakes

Using '*' instead of '**' will multiply but not square.

Using '<' instead of '>' will filter the wrong numbers.

Use ** to square the number and > to filter squares greater than 10.

Fill all three blanks to create a dictionary with uppercase keys, values as numbers, and only include values greater than 2.

Python

result = [1]: [2] for [3], [2] in {'a':1, 'b':3, 'c':5}.items() if [2] > 2}
print(result)

💡 Hint

Common Mistakes

Using 'item' instead of 'k' and 'v' for loop variables.

Not converting keys to uppercase.

Mixing up keys and values in the dictionary comprehension.

Use k.upper() for uppercase keys, v for values, and k as the key variable in the loop.
