How do I convert a simple fraction which updates during each iteration of a loop to a proper progress bar?

Question

I have a loop in my code, which looks somewhat like this:

x = 0
while x < 200:
    # execute some code
    x += 1
    print(x, '/200')
 

How do I convert the print(...) statement present in the last line of the loop to a proper progress bar instead of the fraction it prints?
