String Concatenation in Python

It is an operation of clipping one string to the end of another string. You can use the concatenation operation by using the + sign. % allows you to insert a string into another specified string value.

Both the operators are used to concatenate strings in python. 

When you are operating with a string in python you may need to combine it with another string.

Python provides a number of string methods that can perform string concatenation.

This article will help you out how to use + and %operators to concatenate strings in python.

How are you able to concatenate strings in python?

● String concatenation by using + operator- The + operator allows you to combine two or more strings.

The + operator must be in between the two strings which are to be concatenated.

SYNTAX : print(“string1” + “string2”)

You can use the syntax to merge labels with the employer’s contact information to get your desired results.
some of the examples that merges the data :

Input:

print(“Name:” + “Shivam”)
print (“Department:” + “Clerk”)

Output :

Name: Shivam 

Department: Clerk 

As you have noticed, all two strings on each line have been concatenated with the operator +. Both the lines have been executed with the spaces given in the time of input.

NOTE:

You can only add or clip string data types.
One integer value and one string cannot be added together.
Let’s make it clear through an example

Input 

print(“john” + 22)

Output :

Type error: can concatenate str(not int) to str:

We can resolve this error by using str ()for the conversion of integers to a string. Have a look at this solution 

print(“john” + str(22))

Here are some examples for you to get a clear understanding of concatenation.

1. Clipping variable a with variable b into variable c:

x = "Hello"
y = "World"
z = x + y
print(z)

2. To add a gap between the variables , add a ” “:

a = "Hello"
b = "World"
c = a + " " + b
print(c)

Concatenation of strings by percentage operator:

The % string concept merges a string into another string. This action is commonly known as Python string interpolation.

You can add on insert the string between two strings in a specified place in the string.

print("%s %s" % ("Hey", "Studyber"))

To make it more clear, here are some examples. Have a look at that.

Example no 1.

s1 = 'Hey'
s2 = 'Studyber'

s3 = "%s %s" % (s1, s2)
print('String Concatenation using % Operator =', s3)

s3 = "%s %s from Shivi - %d" % (s1, s2, 2021)
print('String Concatenation using % Operator with Accessing =', s3)

OUTPUT:

String Concatenation using % Operator = Hey Studyber

String Concatenation using % Operator with Accessing = Hey Shivam from Shivi – 2021

Example no2. 

str1 = "Hello"  
str2 = "Studyber"  
print("% s % s" % (str1, str2))  

In both the above cases % is used to concatenate the strings, pass the value and return the final results to the variable.
