Inputs + Multiple Choice?

Question

So I have a task at school, and haven't been able to find out how to do this so I came here.

Is it possible to have an input and have the user be able to write in more than 1 expected string? So I have this so far;
input ("Please enter a command.")
help = input ("Showing available commands: [havent written in all the commands here yet])
But if I were to do something such as put
walk forwards = input ("You walk forwards") after the help = input ...I'd get an error. Any ideas how it can be multiple choice?

Answer 1

I would use multi line comment to display menu on your console,
choice=None
while choice !="0":
print (
'''Main Menu
0-exit
1-something
2-something etc....''')
choice=input ("Choose on of the above")
if choice =="0":
print ("Bye")
break
elif choice=="1":
do something
......
.......
else:
print (choice, " doesn't exist)

Answer 2

I'm not exactly sure what you're trying to do, but if you know the choices in advance you could give the user a numbered list to choose from and then only ask for the respective number with input(), e.g.
print "Available commands:"
print "(1) walk forwards"
print "(2) exit"
choice = input("please enter number")
hope that helps.
