Reverse string in Python (6 different ways)

Python string library doesn’t support the in-built “reverse()” as done by other python containers like list, hence knowing other methods to reverse string can prove to be useful. This article discusses several ways to achieve it. 

# Python code to reverse a string
# using list comprehension()
# Function to reverse a string
def reverse(string):
    string = [string[i] for i in range(len(string)-1, -1, -1)]
    return "".join(string)
s ="CodeHunger";
print ("The original string  is : ",s)
print ("The reversed string(using reversed) is : ", reverse(s))


The original string  is :  CodeHunger
The reversed string(using reversed) is :  regnuHedoC

Time complexity: O(n) 
Auxiliary Space: O(1) 

Explanation: List comprehension create the list of elements of a string in reverse order and then its elements are joined using join(). And reversed order string is formed.
