How to concatenate two strings in Python

# Python program to show  
# string concatenation  
  
# Defining strings  
str1 = "Hello "  
str2 = "Devansh"  
  
# + Operator is used to strings concatenation  
str3 = str1 + str2  
print(str3)   # Printing the new combined string  

Output:

Hello Devansh

Explanation:

In the above example, the variable str1 stores the string "Hello", and variable str2 stores the "Devansh". We used the + operator to combine these two string variables and stored in str3.

Using join() method

The join() method is used to join the string in which the str separator has joined the sequence elements. Let's understand the following example.

Example -

# Python program to  
# string concatenation  
  
str1 = "Hello"  
str2 = "JavaTpoint"  
  
# join() method is used to combine the strings  
print("".join([str1, str2]))  
  
# join() method is used to combine  
# the string with a separator Space(" ")  
str3 = " ".join([str1, str2])  
  
print(str3)  

Output:

HelloJavaTpoint
Hello JavaTpoint

Explanation:

In the above code, the variable str1 stores the string "Hello" and variable str2 stores the "JavaTpoint". The join() method returns the combined string that is stored in the str1 and str2. The join() method takes only list as an argument.

Using % Operator

The % operator is used for string formatting. It can also be used for string concatenation. Let's understand the following example.

Example -

# Python program to demonstrate  
# string concatenation  
  
str1 = "Hello"  
str2 = "JavaTpoint"  
  
# % Operator is used here to combine the string  
print("% s % s" % (str1, str2))  

Output:

Hello JavaTpoint

Explanation -

In the above code, the %s represents the string data-type. We passed both variables's value to the %s that combined the strings and returned the "Hello JavaTpoint".

Using format() function

Python provides the str.format() function, which allows use of multiple substitutions and value formatting. It accepts the positional arguments and concatenates the string through positional formatting. Let's understand the following example.

Example -

# Python program to show   
# string concatenation   
  
str1 = "Hello"  
str2 = "JavaTpoint"  
  
# format function is used here to   
# concatenate the string   
print("{} {}".format(str1, str2))   
  
# store the result in another variable   
str3 = "{} {}".format(str1, str2)   
  
print(str3)   

Output:

Hello JavaTpoint
Hello JavaTpoint

Explanation:

In the above code, the format() function combines both strings and stores into the str3 variable. The curly braces {} are used as the position of the strings.
