reverse a list without built-in functions

Question

How to reverse a list in Python without using built-in functions?

Answer 1

You can do it in 2 ways:

1. Using user-defined-functions
2. Using [::-1] operator

Using user-defined-functions:

EXAMPLE:

def myfunc(a):
    rev_str = []
    for x in a:
        rev_str.insert(0, x)
    return rev_str
print(myfunc([1,2,3,4,5]))

OUTPUT:     

[5, 4, 3, 2, 1]

Using [::-1]:

EXAMPLE:

y=[1,2,3,4,5]
z=y[::-1]
print(z)

OUTPUT:  

[5, 4, 3, 2, 1]
