Comparing Outputs (list) Of Two Functions Returning Wrong Boolean

I wrote two functions largest_number and largest_numbercopied and ran a stress test to compare their results. Both of the functions output a rearranged version of the argument list

Solution 1:

largest_numbercopied removes elements from a, but it's operating on the array that was passed in and not a copy of it. This means that your lines

print(f'numbers= {a}, Result1= {largest_number(a)}')
print(f'numbers= {a}, Result2= {largest_numbercopied(a)}')

will result in a being cleared out and then

iflargest_number(a)== largest_numbercopied(a)

will be comparing the result of operating on an empty list.
