What is a join method and how does it work in python?

Question

I want to know all about the join method.

Answer 1

The join() method is used to return a string, concatenated with iterable(looping) elements.

Note: If there occurs a non-string value during iteration, a TypeError exception is raised. 

code: 

list_a = ['1','2','3','4']  

 

x = "-" 

 

# joins elements of list_a by '-'  

# and stores in sting x

x = x.join(list_a)  

 

# join use to join a list of  

# strings to a separate x  

print(x) 

Explanation: Elements of the list are joined by '-' and are getting stored in x. Join is used to join a list of strings to separator x. Hence, we get the string.
