I need help with ValueError in my code

[flatman123]

Sorry about that:

def inverted_tri(t):
     another_astk = 0
     space = 30
     if type(t) == str:
     t = int(t) # if end-users enters a string, this converts it to an integer
     
     for x in reversed(range(t)):
        if x % 2 == 1:
        print(' ' * space,'#' * x)
        space = space + 1

inverted_tri(' ')

Hello!
First, put your code between Python code tags ( BBcode )! To preserve indentation use CTRL+SHIFT+V key combo to paste the code.

An empty string cannot be converted into an integer. The string is 't', right? You can check for an empty string by if statement easy: if t:. This will return False if 't' == "". Also, you can check if the strings contain digits only by t.isdigit().

thanks for that, i'll try a few things out and let you know.
