Yes, you can [break](https://docs.python.org/3/tutorial/controlflow.html#break-and-continue-statements-and-else-clauses-on-loops). — jpp, May 10 '18 at 14:03
`break` is the answer. This section of the docs explains in more detail: https://docs.python.org/3.6/tutorial/controlflow.html#break-and-continue-statements-and-else-clauses-on-loops — divibisan, May 10 '18 at 14:03

To exit a for or while loop, use the keyword break (docs). This works for "infinite" loops too (like the one below). Example:

n = 0
while True:
    print("Running")
    if n == 3:
        break
    n += 1

will print:

Running
Running
Running
Running

(since it'll run when n is 0, 1, 2 and 3 -> 4 times)
