Basic python - Natters10 - Aug-21-2018
Hi I'm very new to python and have a problem.
def main(): x, y = 10, 100 if (x < y): st = "x is less than y" print (st) if __name__ == "__main__": main()It says NameError, name 'x' is not defined.
Could someone tell me what I've done wrong thanks.

Please use python tags when posting code (see the BBCode link in my signature below for instructions). They present the indentation which is essential to Python, and appears to be the problem here.
The x and y variables are defined in the main function. However, the
if (x < y): conditional is not indented further than the def statement, so it is not part of the function. So it doesn't see the x and y that were defined and raises the error you got. You need to indent lines 4, 5, and 7 one more level. Then it should work.
