How many times will the inner loop execute in the following Python code?

for i in range(3):

      for j in range(2):

            print(i, j)

num = int(input("Please enter a number (0 when done): "))

incr = 0

while num != 0 :

   incr = incr + 1

   num = int(input("Please enter a number (0 when done): "))

print(incr)

j = 10

while j >= 5 :

   print("X")

   j = j - 1

# This code prints the first 10 numbers starting with zero

i = 0

while i <= 10 :

   print(i)

   i = i + 1

What will be printed? 

x = 0

if x:

     print("True")

else:

     print("False")`

a = 10

while a  > 5 :

   a = a - 2

   print(a , end = " ") 

Which of the following is a valid variable name in Python?
