How do I use user input to invoke a function in Python? [duplicate]

Answer 1

The error is because function names are not string you can't call function like 'func1'() it should be func1(),

You can do like:

{
'func1':  func1,
'func2':  func2,
'func3':  func3, 
}.get(choice)()

its by mapping string to function references

side note: you can write a default function like:

def notAfun():
  print "not a valid function name"

and improve you code like:

{
'func1':  func1,
'func2':  func2,
'func3':  func3, 
}.get(choice, notAfun)()
