How to get an if-statement to accept multiple spellings of a string?-CodePudding

I'm working on a little demo of a Command Terminal that stores some stuff (Zones, items held within those zones, etc). I was inspired by this game called GTFO. Anyways, I'm trying to get an If Statement to accept multiple spellings of a command. For instance, the command (Help) could be full uppercase, full lowercase, grammatically correct, etc. However, while it does run up until the input, when I attempt to input Help or any variation of help, it stops dead. Tried dissecting it into a separate variable (helpCommand), but didn't work. Any suggestions?

import sys,time
def slowPrint(text,delayTime):
  for character in text:
    sys.stdout.write(character)
    sys.stdout.flush()
    time.sleep(delayTime)

#Welcome screen.
slowPrint("||Facility Main Command Terminal||\n\nEnter Help for command prompts for The Main Facitliy Command Terminal.",.05)
command = input("\n\n||Please Input Command Below||\n")

#Help Command: Gives system commands.
helpCommand = ["Help", "help", "HELP"]

if command == helpCommand:
 slowPrint("\n||Commands||\n\nZoneList: Zone List lists any and all zones inside the Facility Database.\n\nZoneStock: Zone Stock shows all stocked items within specific zone.\n\nItem: After inputting command, requires the name of item. Lists where a specific item is within a specific zone and what it does.\n\nPersonal: Lists all personal in Facility Database, their work status (Working with company or not, and reason for firing) and their ID number.\n\nPersonalID: Will require an ID after command. Once ID is inputted, it will give all basic info the Personal command gives and some extra tidbits.", .05)

If all you are looking for is case-insensitivity, you can force the case of the input to a particular setting and do the comparison that way:

if command.casefold() == 'help':
    slowPrint("\n||Commands ...")

If you truly have different key words you want to match, use a set or frozenset to provide high-performance in operations:

HELP_COMMANDS = frozenset(word.casefold() for word in ['help', 'sos', 'mayday'])

# ...

if command.casefold() in HELP_COMMANDS:
    slowPrint("\n||Commands ...")

You are checking if the command they give is equal to the entire list of help commands. What you are looking for is:

if command in helpCommand:
    print("Commands")

CodePudding user response：

If the commands just differ in capitalization, you could change it to full uppercase or full lowercase and then just compare:

command = command.lower()
helpCommand = 'help'
if command == helpCommand:
    print('commands')

Then, it won't matter the capitalization, and you can just compare directly.
