Assigning a value to a variable in Python is done by:

• using the = operator

• using the := operator only

• using the == operator

• using the => operator

What will be the output of: python x = 5 y = "5" print(x + int(y))

• 10

• 55

• TypeError

• 5

The difference between // and / operators can be explained with the example: 7 // 2 gives 3, while 7 / 2 gives 3.5. Which of the following best describes this difference?

• Both // and / give the same result for all numbers.

• // is used for multiplication, while / is used for division.

The % operator is used for which of the following purposes?

• To find the remainder after division of two numbers

• To perform exponentiation

• To calculate the average of two numbers

• To find the quotient after division of two numbers

What is the result of: python x = 10 x += 5 print(x)

• 10

• 5
