'else' statement not executing

[sparkz_alot]

I've been scratching my head for quite awhile on this. The problem being the 'else' statement doesn't run, or at least doesn't get me to "def opt2():" though the print function I added shows that the option should run. Am I missing something? Obviously I am, but if it's simple, please make it sound complicated so I don't feel stupid.

The code:

#!/usr/bin/env/python3


def opt1():
   print("in opt 1")

   return


def opt2():
   print("in opt 2")

   return


def opt3():
   print("in opt 3")

   return


def main_mnu():
   print('This is the Main Menu. Please make a selection.')
   print('    1) opt1')
   print('    2) opt2')
   print('    3) opt3')
   opt_num = [0, 1, 2]
   main_opt = ['opt1', 'opt2', 'opt3']

   while True:
       try:
           choice = abs(int(input('Enter choice: ')))
           if choice == min(opt_num) + 1:
               opt1()
               break
           elif choice == max(opt_num) + 1:
               opt3()
               break
           else:
               main_opt[choice - 1] + '()'
               print(main_opt[choice - 1] + '()')
               break
       except (IndexError, ValueError) as e:
           print('Not an option, try again.', e)
           continue


if __name__ == '__main__':
   main_mnu()

The result:

Output:
C:\Python\test.py
This is the Main Menu. Please make a selection.
   1) opt1
   2) opt2
   3) opt3
Enter choice: 1
in opt 1

C:\Python\test.py
This is the Main Menu. Please make a selection.
   1) opt1
   2) opt2
   3) opt3
Enter choice: 3
in opt 3

C:\Python\test.py
This is the Main Menu. Please make a selection.
   1) opt1
   2) opt2
   3) opt3
Enter choice: 2
opt2()    # result of print function, but not getting to the 'def opt2():'

Thanks for any insight.

Change

main_opt = ['opt1', 'opt2', 'opt3']

to

main_opt = [opt1, opt2, opt3]

and

main_opt[choice - 1] + '()'

to

main_opt[choice - 1]()

your code

main_opt[choice - 1] + '()'

just creates a string that you don't use at all -i.e. you don't assign it to a variable.

Of course you can always do

eval(main_opt[choice - 1] + '()')

Actually, I would do

#!/usr/bin/env/python3

def opt1():
   print("in opt 1")
   return


def opt2():
   print("in opt 2")
   return


def opt3():
   print("in opt 3")
   return


def main_mnu():
   print('This is the Main Menu. Please make a selection.')
   print('    1) opt1')
   print('    2) opt2')
   print('    3) opt3')

   main_opt = {'1':opt1, '2':opt2, '3':opt3}

   while True:
       choice = input('Enter choice: ')
       try:
            main_opt[choice]()
            break
       except KeyError as err:
            print('Not an option, try again.', err)


if __name__ == '__main__':
   main_mnu()

[sparkz_alot]

eval(main_opt[choice - 1] + '()')

Thank you buran, that does the trick. I will try and use your preferred solution (using the dictionary) but that will take some time to reconfigure my script.

Thanks again.

I am working on that tutorial you asked for sparkz, I'm almost finished with it. I hope to have it posted by the end of the week.
