How to reverse string in Python ?

Different ways to reverse String in Python.

String is a widely used datatype in Python just like a list. In most of the interviews, a question was asked How to reverse a string in Python?
In this article, we will see a different way to reverse a String in Python.

1. Using Extended Slice Syntax:

Extended slice method takes three parameters [ start index: end index: increment ] just like the for a loop.

Example:

testString = 'Neptuneworld' testString=testString[::-1] print(testString)

Output:

2.Using BuildIn method Reversed():

Reversed method returns a string reversed object which we can see that’s why we use to join and convert that object to a string using join.

Example :

testString = 'Neptuneworld' testString=””.join(reversed(testString)) print(testString)

Output :

3. Using for loop:

In this method, we iterate the string and add the element to the start of initialized empty string.

Example:

testString = 'Neptuneworld' revString = str() for ch in testString: revString = ch + revString print(revString)

Output:

4.Using Recursive Function:

def reverse(testString): if len(testString) == 0: return testString else: return reverse(testString[1:]) + testString[0] print(reverse("NeptuneWorld"))

5.Using List  :

Using list also we can reverse the string as shown below.

testString = 'Neptuneworld' revString = [] for i in range(len(testString)-1,-1,-1): revString.append(testString[i]) print(''.join(revString))
