how to make a repeated loop in python

1variable = 'thing'
2for i in range(50):
3  print(variable)
4 
5# or you can do something like this
6for i in range(50, 2):
7  print(variable)
8  
9# and a while loop repeats forever
10while True:
11  print(variable)
12
13# a while loop also works like this
14runcheck = True
15while runcheck:
16  for i in range(10):
17    print(variable)
18  runcheck = False
