Practice - 5 Tasks

1fill in blank

easy

Complete the code to print numbers from 1 to 5 using a loop.

Python

for i in range(1, [1]):
    print(i)

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

💡 Hint

Common Mistakes

Using 5 as stop will print 1 to 4 only.

The range function stops before the end number, so to print 1 to 5, we use 6 as the stop.

2fill in blank

medium

Complete the code to stop the loop when i equals 3.

Python

for i in range(1, 6):
    if i == [1]:
        break
    print(i)

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

💡 Hint

Common Mistakes

Using break with wrong value stops loop too early or too late.

The break stops the loop when i is 3, so numbers 1 and 2 print only.

3fill in blank

hard

Fix the error in the loop to skip printing number 3.

Python

for i in range(1, 6):
    if i == [1]:
        continue
    print(i)

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

💡 Hint

Common Mistakes

Using continue with wrong value skips wrong number.

The continue skips the current loop when i is 3, so 3 is not printed.

4fill in blank

hard

Fill both blanks to create a dictionary of squares for numbers greater than 2.

Python

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

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

D<

💡 Hint

Common Mistakes

Using + instead of ** changes meaning.

Using < instead of > filters wrong numbers.

Use ** to square numbers and > to filter numbers greater than 2.

5fill in blank

hard

Fill all three blanks to create a dictionary with uppercase keys and values greater than 0.

Python

result = [1]: [2] for k, v in data.items() if v [3] 0}

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

💡 Hint

Common Mistakes

Using k instead of k.upper() keeps keys lowercase.

Using < instead of > filters wrong values.

Keys are converted to uppercase with k.upper(), values are v, and filter keeps values greater than 0.
