Find the output of the following code:

p = 5 % 2
q = p ** 4
r = p // q
p+= p + q + r
r+= p + q + r
q-= p + q * r
print(p, q, r)

4 -10 7

Working

p = 5 % 2

The modulo % operator calculates the remainder of the division.

• 5 \% 2 = 1
• Thus, p = 1

q = p ** 4

The exponent ** operator raises p to the power of 4.

• 1 ** 4 = 1
• Thus, q = 1

r = p // q

The floor division // operator divides and returns the integer quotient of the division.

• 1 // 1 = 1
• Thus, r = 1

p += p + q + r

The += operator adds the value on the right to the variable and assigns it to the variable again.

• Initially, p = 1
• Calculation inside the parentheses: (p + q + r) = 1 + 1 + 1 = 3
• p += 3 means p = p + 3
• So, p = 1 + 3 = 4

r += p + q + r

The += operator adds the value on the right to the variable and assigns it to the variable again.

• Initially, r = 1
• Calculation inside the parentheses: (p + q + r) = 4 + 1 + 1 = 6
• r += 6 means r = r + 6
• So, r = 1 + 6 = 7

q -= p + q * r

The -= operator subtracts the value on the right from the variable and assigns it to the variable again.

• Initially, q = 1
• Calculation inside the parentheses: (p + q * r) = 4 + 1 * 7 = 4 + 7 = 11
• q -= 11 means q = q - 11
• So, q = 1 - 11 = -10

print(p, q, r)

The variables now have these final values:

• p = 4
• q = -10
• r = 7

Hence, the output of the program is:

4 -10 7
