I am trying to execute the command
abs.__ doc__ inside the
exec() function but for some reason it does not work.
function = input("Please enter the name of a function: ") proper_string = str(function) + "." + "__doc__" exec(proper_string)
Essentially, I am going through a series of exercises and one of them asks to provide a short description of the entered function using the
__ doc__ attribute. I am trying with
abs.__ doc__ but my command line comes empty. When I run python in the command line and type in
abs.__ doc__ without anything else it works, but for some reason when I try to input it as a string into the
exec() command I can’t get any output. Any help would be greatly appreciated. (I have deliberately added spaces in this description concerning the attribute I am trying to use because I get bold type without any of the underscores showing.)
As a note, I do not think I have imported any libraries that could interfere, but these are the libraries that I have imported so far:
import sys import datetime from math import pi
My Python version is Python 3.10.4. My operating system is Windows 10.
abs.__doc__ is a string. You should use
eval instead of
exec to get the string.
function = input("Please enter the name of a function: ") proper_string = str(function) + "." + "__doc__" doc = eval(proper_string)
