Question

What will be printed to the screen when this program is run?

for j in range(2):
for i in range(0, 2, 1):
print(i)

Answer 1

When the Python program with nested for loops is executed, it will print the sequence '0 1 0 1', with the sequence '0 1' being printed twice due to the loops' range settings.

Step-by-step explanation:

The student is asking what will be printed on the screen when the given Python program is run. The Python code is using a nested for loop where the outer loop will run 2 times because 'range(2)' generates numbers from 0 to 1. Each time the outer loop runs, the inner loop will also run 2 times because 'range(0, 2, 1)' generates numbers from 0 to 1, incrementing by 1. The inner loop prints the value of 'i' each time it runs.

When the program is executed, it would output:

• 0
• 1
• 0
• 1

The sequence '0 1' is printed twice because 'j' takes on the values 0 and 1, and for each value of 'j', 'i' also takes the values 0 and 1.
