Armstrong in minimum lines - Gaurav - Sep-03-2018 Hey guys. I've just started learning python. Made a simple armstrong program and need help on it. Basically I wanna know how to nest for loops. Here goes my program num = 371 #int(input("Enter a number:")) list = [int(i) for i in str(num)] pow = [int(d**3) for d in list] print("YES" if sum(pow) == num else "NO") My problem is : 1. I have to create list of the num variable to split the numbers 2. Then I have to find power of 3 of each num in the list I want to do both the things in one line. Maybe somewhat like list = [int(i**3) for i in str(num)] But this gives me an error that says : Traceback (most recent call last): File "C:/Users/Gaurav/PycharmProjects/Armstrong/Armstrong.py", line 2, in <module> list = [int(i**3) for i in str(num)] File "C:/Users/Gaurav/PycharmProjects/Armstrong/Armstrong.py", line 2, in <listcomp> list = [int(i**3) for i in str(num)] TypeError: unsupported operand type(s) for ** or pow(): 'str' and 'int' Any help is appreciated. #Sorry for my bad english though RE: Armstrong in minimum lines - j.crater - Sep-03-2018 Please put your code in Python code tags and errors error tags.
