How to Concatenate Strings in Python

String concatenation is a common task in most applications. In this article, we will look into different ways to concatenate strings in Python.

1.Using the + operator

To concatenate strings we can use the + operator.

str1 = "Happy"
str2 = "Coding"

result = str1 + str2
print(result)

Output

HappyCoding

Here string str1 and str2 are joined using the + operator. We can add space between str1 and str2 as shown below.

str1 = "Happy"
str2 = "Coding"

result = str1 + " " + str2
print(result)

Output

 Happy Coding

2.Using the string join() method

We can join strings using the join method. The join method returns a string by joining all the elements of iterable (string, list, tuple) separated by a string separator.

str1 = "Happy"
str2 = "Coding"

result = " ".join([str1,str2])
print(result)

Here we converted str1 and str2 into list [str1,str2] and separator is space (” “). The join method will combine str1 and str2 strings, separated by space.

Output

Happy Coding

3.Using the string formatting % operator

We can join strings using the string formatting % operator as shown below.

str1 = "Happy"
str2 = "Coding"

result  = "%s %s" % (str1,str2)
print(result)

Here %s (format specifier for string) is replaced by the corresponding strings (str1 and str2).

Output

Happy Coding

4. Using the string formatting { } operator

We can join the strings using the {} operator. When we use string format function with curly braces or {} it act as a placeholder for the variables.

str1 = "Happy"
str2 = "Coding"

result  = "{} {}".format(str1,str2)
print(result)

Output

Happy Coding

5. Join the same string the * operator

And finally, we will look into * operator. Using this operator we can repeat string n times.

result = string * n  #n= number of times 

Let’s look into an example

str1 = "Happy"
result  = str1 * 3
print(result)

We can see that result has the value “HappyHappyHappy”, str1 is repeated 3 times.

Output

HappyHappyHappy
