How do you create an infinite while loop in Python?

What is the purpose of the range() function in Python?

How do you use a while loop to count from 1 to 10?

• repeat until count > 10: print(count); count = count + 1

• for count in range(1, 11): print(count)

• while count <= 10: print(count); count += 1

• count = 1; while count < 10: print(count); count++

What is the difference between break and continue statements?

• The 'break' statement skips to the next iteration, while 'continue' exits the loop.

• The 'break' statement is used only in switch cases, while 'continue' is for loops.

• Both 'break' and 'continue' exit the loop but have different conditions.

• The 'break' statement exits a loop, while the 'continue' statement skips to the next iteration of the loop.

What will be the output of the following code: for i in range(5): print(i)?

• 10

• 0 1 2 3 4

How do you ensure a while loop eventually stops executing?

• Modify the loop condition or a variable within the loop to ensure it will eventually evaluate to false.

• Remove the loop condition entirely.

• Use a break statement without a condition.

• Increase the loop counter indefinitely.

What will be the output of the following code: for i in range(3): print(i * 2)?
