Unfortunately, I only found Python REPLs for version 2.7.2 or lower.
Is there a REPL for 3.3.0 ..?
The REPL (read–eval–print loop) is the >>> prompt.

Oh, I didn't even know that such a thing exists :-) Cool!

No, it's not none. It's an empty list; thus, python executes nothing inside the
inner loop.

thank you *so much" for explaining the concept of a nested for loop!
Your simplified example Steven made it very clear to me:
for x in range(2, 7):
print("outer loop, x =", x)
for y in range(2, x):
print("inner loop, x =", x, "y =", y)

Hej there,
I noticed that sometimes when I do lots of modifications within a
program, I get runtime errors even if the program is "clean". I
realized that first time when I copy and pasted a program into a new
window - it miraculously ran without any problems. Although it was
exactly the same prog
