Create a Python program to find the the largest and smallest in a list
numbers = [234, 534, 123, 42, 56, 1, 234]
def find_limits(numbers):
    largest = numbers[0]
    smallest = numbers[0]
    for num in numbers:
        if num > largest:
            largest = num
        if num < smallest:
            smallest = num
    
    return largest, smallest
