Practice - 5 Tasks

1fill in blank

easy

Complete the code to print a message only if the number is positive.

Python

number = 5
if number [1] 0:
    print("Number is positive")

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

A>

B<

C==

D!=

💡 Hint

Common Mistakes

Using '<' will check if the number is negative, which is not what we want.

The condition number > 0 checks if the number is positive.

2fill in blank

medium

Complete the code to print 'Even' if the number is divisible by 2.

Python

number = 8
if number [1] 2 == 0:
    print("Even")

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

A%

B//

C**

D+

💡 Hint

Common Mistakes

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

The modulus operator % gives the remainder. If remainder is 0, number is divisible by 2.

3fill in blank

hard

Fix the error in the code to check if a number is not zero.

Python

number = 0
if number [1] 0:
    print("Number is not zero")

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

A>=

B==

C!=

D<=

Attempts:

💡 Hint

Common Mistakes

Using '==' checks equality, which is the opposite of what we want.

The operator != means 'not equal to', so it checks if number is not zero.

4fill in blank

hard

Fill both blanks to create a dictionary of squares for numbers greater than 3.

Python

squares = {x: x[1]2 for x in range(1, 6) if x [2] 3}

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

A**

B%

C>

D<

Attempts:

3 left

💡 Hint

Common Mistakes

Using '%' instead of '**' will not square the number.

Use ** to square the number and > to check if number is greater than 3.

5fill in blank

hard

Fill all three blanks to create a dictionary of uppercase keys and values greater than zero.

Python

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

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

Ak.upper()

Bv

C>

Dk

Attempts:

💡 Hint

Common Mistakes

Using 'k' instead of 'k.upper()' will not change key case.

Use k.upper() to make keys uppercase, v as values, and > to filter values greater than zero.
