Coding Error in visual studio

Hello all. I’m trying to figure why visual studios says I need to define a variable. and where to define it. I have the whole code at GitHub - jamesboeck/MPG: a Mutiple application in one.

"for user_choice in user_choices:
   " user_choice = user_choice.strip()  # remove leading/trailing spaces
    if user_choice in options:
        "optionsuser_choice""

I’m quoting more of your code for context.

def main_new():
    options = {
        '1': calculate_travel_time,
        '2': main,
        '3': calculate_gas_mileage_main
    }

    while True:
        print('1: Calculate travel time')
        print('2: Calculate MPG for your trip')
        print('3: Calculate the effect of temperature on MPG')
        user_choices = input('Enter the numbers corresponding to your choices, separated by commas: ').split(',')
        for user_choice in user_choices:
            user_choice = user_choice.strip()  # remove leading/trailing spaces
            if user_choice in options:
                optionsuser_choice
            else:
                print(f"Invalid choice: {user_choice}. Please enter a valid number.")

The variable optionsuser_choice is not defined in your code. It looks like you are trying to call a function stored in the options dictionary.

To do that replace

optionsuser_choice

with

chosen_function = options[user_choice] # get the function 
chosen_function() # call the function

This can be more succinctly written as

options[user_choice]()
