Hi,
the following code generates an error at the line where isdigit() is used.
isdigit() is part of standard Python libs, so I wonder how to get it working.
import RLPy
def run_script(): val = 100 if val.isdigit(): print("it is a digit") else: print("it is not a digit")
Thanks
Roberto

Actually, isdigit() refers to a string.
This works in iClone Python:
str = "1234"
print(str.isdigit())
returns true.

Hi Mike,
oh... that's right.
So, I need to check how to use for a function input parameter (that's the diea: to check whether it is a number)...

Well, it has to be *something* to begin with -- either it's a number, or it's a string that may or may not contain numbers.
If it's a string and you're not sure if it's all digits, you can use that function (so "A103" would return false).
And if you're not sure what type it is, use the function type().

Ok, my point is to check function parameters for type consistency.
I am an old C programmer and I learnt to use strict conventions... that's why Python for me is just too loose...

Yeah, Python won't do that.
Here's some explanation of this process: https://stackoverflow.com/questions/402504/how-to-determine-a-python-variables-type

@Roberto and Mike,
It's fun and fascination watching the two of you work together. I'm sorry you need to do all this reverse engineering and forensic discovery to figure out how it should work, and never knowing for sure if it's a bug, a documentation error, or user error.
On behalf of all the people who will benefit from your pioneering efforts, "Thank you!"

Yeah...
Mike has promised to invite me in Florida if I can help him... right Mike ?

You and Dennis are always welcome here (we don't have a ton of guest room, but I'm sure we can work something out).

Could be more than just an idea...

And I'm serious about it (I'm a pretty great host :>.
