Loop control: break, continue, pass

In addition to using comments to document your code, sometimes a hash mark can be used to comment out code that you won't execute right now. This can be useful for debugging or testing. Commented out code looks like this:

name = 'John'
age = 10
# name = 'asdfghjkl'
# age = -999
print(name + ' ' + str(age))

Here, lines 3 and 4 are commented out and won't be executed when we run the code.

The code snippet below does the following: it asks the user to guess a random number from 1 to 5, then prints "Yes!" if the user has guessed correctly and "No!" otherwise. The problem is that it does so only 5 times. Which line of code must be commented out if we want our code to ask the user endlessly? Type the line number.

import random                      # 1
                                   # 2
n_guesses = 0                      # 3
while n_guesses < 5:               # 4
    number = random.randint(1, 5)  # 5
    guess = int(input())           # 6
    if guess == number:            # 7
        print('Yes!')              # 8
    else:                          # 9
        print('No!')               # 10
    n_guesses += 1                 # 11
