Split String into List of characters in Python

Python - Insert characters at start and end of a string

Last Updated : 06 Dec, 2024

In Python programming, a String is an immutable datatype. But sometimes there may come a situation where we may need to manipulate a string, say add a character to a string.

Let’s start with a simple example to insert characters at the start and end of a String in Python.

Python

s = "For"
s2 = "Geeks"

r = s2 + s + s2
print(r)

Output:

GeeksForGeeks

Explanation: The word "Geeks" is inserted at the start and the end of the string "For". As there is no white space in any of the strings, the words are joined together as one word.

Using String Concatenation

The most common way to join two or more strings is using the String Concateniation method, which used the "+" operator to combine the strings

Python

s = "GeeksForGeeks"

# inserting same characters
r = "Hello" + s + "Hello"
print(r)

# inserting different characters
r = "Hello" + s + "World"
print(r)

Output:

HelloGeeksForGeeksHello
HelloGeeksForGeeksWorld

Using join() Function

The join() function is also used to concatenate two or more strings in Python. It takes an iterable, that is a list or a tuple as the parameters and join them in the given order.

Python

s = "GeeksForGeeks"

# inserting same characters
r = "".join(["Hello", s, "Hello"])
print(r)

# inserting different characters
r = "".join(["Hello", s, "World"])
print(r)

Output:

HelloGeeksForGeeksHello
HelloGeeksForGeeksWorld

Using f-String

The f-string in Python is used in string formatting. It directly embeds the expression inside the curly braces.

Python

s = "GeeksForGeeks"

# inserting same characters
r = f"Hello{s}Hello"
print(r)

# inserting different characters
r = f"Hello{s}World"
print(r)

Output:

HelloGeeksForGeeksHello
HelloGeeksForGeeksWorld

Using format() Function

The Python format() function is an inbuilt function used to format strings. Unline f-string, it explicitly takes the expression as arguments.

Python

s = "GeeksForGeeks"

# inserting same characters
r = "Hello{}Hello".format(s)
print(r)

# inserting different characters
r = "Hello{}World".format(s)
print(r)

Output:

HelloGeeksForGeeksHello
HelloGeeksForGeeksWorld

Get Last N characters of a string - Python

We are given a string and our task is to extract the last N characters from it. For example, if we have a string s = "geeks" and n = 2, then the output will be "ks".

Reverse Alternate Characters in a String - Python

Reversing alternate characters in a string involves rearranging the characters so that every second character is reversed while maintaining the original order of other characters. For example, given the string 'abcde', reversing the alternate characters results in 'ebcda', where the first, third and

Replace a String character at given index in Python

In Python, strings are immutable, meaning they cannot be directly modified. We need to create a new string using various methods to replace a character at a specific index.

Splitting String to List of Characters - Python

We are given a string, and our task is to split it into a list where each element is an individual character. For example, if the input string is "hello", the output should be ['h', 'e', 'l', 'l', 'o']. Let's discuss various ways to do this in Python.Using list()The simplest way to split a string in

Splitting String to List of Characters - Python

The task of splitting a string into a list of characters in Python involves breaking down a string into its individual components, where each character becomes an element in a list. For example, given the string s = "GeeksforGeeks", the task is to split the string, resulting in a list like this: ['G

Python - Right and Left Shift characters in String

In string manipulation tasks, especially in algorithmic challenges or encoding/decoding scenarios, we sometimes need to rotate (or shift) characters in a string either to the left or right by a certain number of positions.For example, let's take a string s = "geeks" and we need to perform a left and

Python - Replace Different Characters in String at Once

The task is to replace multiple different characters in a string simultaneously based on a given mapping. For example, given the string: s = "hello world" and replacements = {'h': 'H', 'o': '0', 'd': 'D'} after replacing the specified characters, the result will be: "Hell0 w0rlD"Using str.translate(

Remove Character in a String at a Specific Index in Python

Removing a character from a string at a specific index is a common task when working with strings and because strings in Python are immutable we need to create a new string without the character at the specified index. String slicing is the simplest and most efficient way to remove a character at a
