In Python, string concatenation refers to the process of combining two or more strings into a single string. There are various ways to concatenate strings in Python, which are explained in this tutorial.
Concatenate Strings Using + Operator
To concatenate (combine) two strings in Python, the + operator can be used.
Example Program:
string1 = "W3schools"
string2 = ".in"
result = string1 + string2
print(result)
The above example will print "W3schools.in".
Concatenate Strings Using join() Method
In Python, the join() method is a string method that concatenates (combines) a list of strings into a single string. This method takes a list of strings as an argument and returns a single string which is the concatenation of all the strings in the list.
Example Program:
strings = ["Hello", "Python", "Test"]
result = "".join(strings)
print(result)The above program will print "HelloPythonTest".
A separator string can also be used with the join() method to insert a separator between the strings. For example:
Example Program:
strings = ["Hello", "Python", "Test"]
result = " ".join(strings)
print(result)The above program will print the "Hello Python Test" because the separator is a space character.
Concatenate Strings Using F-String
The f-strings feature introduced in Python 3.6 can be used to concatenate strings. An f-string is a string literal prefixed with the letter f and allows you to embed expressions inside a string. For example:
Example Program:
string1 = "Hello"
string2 = "Python"
result = f"{string1} {string2}"
print(result)The above program will also print "Hello Python".
