Using a while loop to repeat lines of code starts with the while keyword.
while True:
print("and again")
A while loop repeats its code block while its condition is True. We code a True condition with True followed by a colon :.
while True:
print("and again")
The code the while loop repeats comes after the :, inside the indented code block. Like the print() statement here.
while True:
print("and again")
If a while loop's condition stays True forever, we call it an infinite loop since it will loop infinitely, like with print() here.
while True:
print("and again")
