[solved] list content check

[deanhystad]

Depending on how many strings you have to check I would use sets:

def check_list(items, must_have):
    """Return True if items list has all elements in must_have list."""
    items = {x.lower() for x in items}
    must_have = set(must_have)
    return items & must_have == must_have


print(check_list(["xxXx", "YyYy"], ("xxxx", "yyyy")))
print(check_list(["xxXx", "YyYy", "ZZZZ"], ("xxxx", "yyyy")))
print(check_list(["xxXx", "YyYy"], ("xxxx", "zzzz")))

Output:
True
True
False

Or I would use all()

def check_list(items, must_have):
    """Return True if items list has all elements in must_have list."""
    items = [x.lower() for x in items]
    return all(x in items for x in must_have)


print(check_list(["xxXx", "YyYy"], ("xxxx", "yyyy")))
print(check_list(["xxXx", "YyYy", "ZZZZ"], ("xxxx", "yyyy")))
print(check_list(["xxXx", "YyYy"], ("xxxx", "zzzz")))

Avoid calling functions more often than needed. Instead of calling lower() for each comparison, create a new list that has lowercase versions of MyList strings.
