While Loop Creating

I am writing a program in Python that defines a function that takes a single argument. The function has to be a while loop the returns the largest power of 16 that it is equal to.

Solution 1:

Python Docs

while True:
    n = input("Please enter 'hello':")
    if n.strip() == 'hello':
        break

so, in layman's terms

while <condition>:
    ...

Solution 2:

I couldn't completely understand your question but here's how to do a while loop to get the x to the 16th power of an input:

def loop_function(x):
    y = 1
    start = x
    while y != 16:
        result = start * x
        start = result
        y += 1
    return result

print loop_function(3)

The above code will return the answer to 3^16 which is 43046721

You can even make this a broader function two arguements

def loop_function(x, y):
    z = 1
    start = x
    while z != z:
        result = start * x
        start = result
        z += 1
    return result

print loop_function(3, 2)

The above code will return 9 i.e 3^2
