Append To String Python Examples

In Python, the string is an object that can’t be changed.

By adding two strings together with the “+” operator, you can make a new string.

There are many ways to do this, such as using join, format, string IO, and appending the strings with space.

Python Append String

Use the += operator in Python to append a string to another string.

The += operator in Python joins two strings together. It adds up two numbers and gives the total to a variable.

There are other ways you can append to a string.

1. Using string.join() method
2. Using Python f-strings

Append String Using += Operator In Python

When you use the += (plus equal operator) to concatenate two strings together, a new string is made, but the original string stays the same.

You can use the (+=) operator to do the append task.

Example:

fname = "AngelJude"
lname = "Suarez"

# printing fname string
print("The first name: " + str(fname))

# printing lname add string
print("The last name : " + str(lname))

# Using += operator adding one string to another
fname += lname

# print result
print("The concatenated string is: " + fname)

When you execute the program, this will be the output:

The first name: AngelJude
The last name : Suarez
The concatenated string is: AngelJudeSuarez

Explanation:

First, we defined two strings, and we will append the second string named “Suarez” to the first string named “AngelJude.“

Then, we printed the two strings, and then we used the += operator to concatenate or append two strings.

Append String Multiple Times In Python

By making a separate function, you can append strings more than once.

Let’s make a user-defined function that adds the string to the original string n times.

Example:

str = 'Jude'


def string_append(s, n):
    op = ''
    i = 0
    while i < n:
        op += s + '-'
        i = i + 1
    return op


pstring = string_append(str, 5)
print(pstring)

When you execute the program, this will be the output:

Jude-Jude-Jude-Jude-Jude-

Explanation

In this example, we made a string and a function that takes str and the number of times as inputs.

Then, we use a while loop to join the strings together until they reach the number of times we set, and it stops when the condition becomes False.

The function string_append() returns multiple strings that have been joined together.

String joint() Method To Append A String

Use the string join() method in Python to append to a string.

To do this, you must make a list and append the strings to it.

Then, use the string join() function to combine them into one long string.

Example:

fname = "AngelJude"
lname = "Suarez"

# printing fname string
print("The first name: " + str(fname))

# printing lname add string
print("The last name : " + str(lname))

# Create a list of Strings
listOfStrings = [fname, lname]

finalString = "".join(listOfStrings)

# print the final result
print("The appended string is: " + finalString)

When you execute the program, this will be the output:

The first name: AngelJude
The last name : Suarez
The appended string is: AngelJudeSuarez
