Question

Why do we use join() function in Python?

Answer 1

The join() is defined as a string method which returns a string value. It is concatenated with the elements of an iterable. It provides a flexible way to concatenate the strings. See an example below.

Example:

1. str = "Rohan"  
2. str2 = "ab"  
3. # Calling function    
4. str2 = str.join(str2)    
5. # Displaying result    
6. print(str2)  

Output:

aRohanb
