how to generate a call for an objects __doc__ special attribute using a defined variable?

Question

Trying to work out how to generate a call for an objects __doc__ special attribute by using a defined variable to populate the first part of the call. When I try this the variable name is treated as if it is a string so the docstring for strings comes up. Works okay to call the help info but not the docstring info.

Any suggestions? Thanks.

Based on all the previous answers, here is a solution, without eval().

Answer 2

def get_some_info():
ui = (input('Type the name of the function you want to find out more about: '))
hds = (input("Type 'ds' for the doc string or 'h' for the help info: "))
if hds == 'ds':
print(eval(ui + ".__doc__"))
elif hds == 'h':
return help(ui)

get_some_info()
