Great! So far, our while loops only ended when the loop condition was satisfied. However, we can also decide to end a loop inside it:
user_input = input('Please provide a number: ')
while True:
if user_input.isnumeric():
break
user_input = input('Not a number! Please provide a number: ')
print('Your number is:', user_input)
while True is used to introduce an infinite loop – the condition True is always true. However, inside the loop, we provided the following if statement:
if user_input.isnumeric(): break
The break keyword is used to terminate the whole loop. Once the user provides a real number, the loop immediately finishes.
Keep asking the user to write the year in which Python was first released: 'In which year was Python first released? '
When the answer is finally correct (1990), print: Correct!
Use a break statement.
Remember to use int() to convert from string to int.
