Python Pre-set options

[Mani_digital415]

Hey, really out of practice (even with i'd still be novice)

Wanted to have preset options that the user can pick and have 3 additional preset options come up. Format may be a little wonky since I did this in Pycharm for it to run properly:

print("Welcome!")
print("How do you want to start today?")
input()
if input() == "Option 1"
print(Sub_option 1, Sub_option 2, Sub_option 3)
else input() == "Option 2"
print(Sub_option 1, Sub_option 2, Sub_option 3)
input()

** Wasnt too sure if I could fit another elsif statement into it, like I would for any other container

Maybe something like this

print('Welcome')
print('How to start')
print('Enter either 1 or 2 and press enter')
# Usinga try except block to ensure an integer is entered
# If not throw an error
try:
    # Option will be a whole number so use int around input
    option = int(input('>> '))
   
    if option == 1:
        print('You chose option 1')
    elif option == 2:
        print('You chose option 2')
    else:
        print('Some other option')
except ValueError as err:
    print('Invalid character. Please enter a whole number.')

If there are going to be a lot of options or you are calling functions, might be better to use a dict or list to store choices.

Yeah theres going to be a bunch of options, ill input the list first, then fix the code

An example of how a dict might be used. Keep in mind that there is no kind of error checking or validation other than checking for a whole number.

def option1():
    return 'sub-options for option 1'

def option2():
    return 'sub-options for option 2'

option_dict = {
1: option1(),
2: option2()
}

print('Welcome')
print('How to start')
print('Enter either 1 or 2 and press enter')
# Usinga try except block to ensure an integer is entered
# If not throw an error
try:
    # Option will be a whole number so use int around input
    option = int(input('>> '))

    # Loop through dict and execute a function if key == option
    for key, value in option_dict.items():
        if option == key:
            print(value)
# Throw an error if invalid character entered
except ValueError as err:
    print('Invalid character. Please enter a whole number.')

If I wanted to use something other than an integer for option would this still be reccomended? I figured add like option 1 being first food choice or option 2 being second food choice

In my opion using dicts or list is best for alot of options. Again that's my pref. Numbers can be changed to text. As I said before dicts take a key, value pair.
so options could be like

dict_options = {
    'hamburger': option1(),
    'hotdog': option2()
}

The code would need to be written a little different.

Thank you, going to take another crack at it
