5 different ways to reverse a string in Python

reverse_string.py

# 1. Slicing
def reverse_slicing(s):
    return s[::-1]

# 2. Looping with for and while loops
    # 2.1 for loop
def reverse_for_loop(s):
    s1 = ""
    for c in s:
        s1 = c + s1
    return s1
    
    # 2.2 while loop
def reverse_while_loop(s):
    s1 = ""
    l = len(s) - 1
    while l >= 0:
        s1 += s[l]
        l -= 1
    return s1

# 3. str.join() Method
def reverse_with_join(s):
    return "".join(reversed(s))

# 4. list.reverse() Method
def reverse_with_list(s):
    s_as_list = list(s)
    s_as_list.reverse()
    return "".join(s_as_list)

# 5. Recursion
def reverse_recursively(s):
    if len(s) == 0:
        return s
    else:
        return reverse_recursively(s[1:]) + s[0]
