In future, it'd be easier for us if you include the text inline. It's
not particularly long, so I'll just do that for you here.

    x = str(input("Welcome Adventurer, what is your name?"))
    if x==('load'):
        y = str(input("messages, places or things?"))
        if y in("messages", "places","things"):
            print("OK")
        else: print("Wrong")

while True:
    startandload


The problem is right at the end: you don't actually call the function.
You always need parentheses to call a function. I'm also a bit
confused as to your reason for running a function called
"startandload" (which seems to be initialization) in an infinite loop;
you possibly just want to call it once.

Note that input() already returns a string, so passing it through
str() doesn't do anything.

`startandload` also takes a parameter that doesn't seem to be used.

Or perhaps:

     if __name__ == '__main__':
         startandload()
