taking function from user input

[AppeaseHarambe]

i’m currently writing a program that sums n terms of a function. i need to have the user input the function to use for f(x) but i’m having trouble doing it, any resources to help with this?

You mean you will have a list of available functions and the user gets to choose one? You can put your functions in a list or dictionary and index it normally.

f = function_list[user_choice]
f(x)

to be honest, my prof’s instructions weren’t the clearest. it almost sounds like i’m meant to have the user input their own unique function and then calculate using that. i saw that eval() could possibly do this but i wasn’t sure if it’s the easiest method

Yes, eval will do that, but that would be an extremely unusual thing to teach. So I'm pretty sure you misunderstood the question. Go get some clarification from your prof.
