String Join() Method

In Python, When elements of a sequence are separated by a string separator, Python’s built-in join() method is used to connect the segments. In order to create a string, this function connects the components of a sequence.

Python Strings Join()

The join() method in python is a string method and returns a string in which the elements of a sequence have been joined by a string separator.

Example : list=[1,2,3,4]

- 1-2-3-4

Syntax :

  string_name.join(iterable)
  string_name: It is the name of string in which joined elements of iterable will be stored.

Return Value: The join() method returns a string concatenated with the elements of iterable.

Type Error: If the iterable contains any non-string values, it raises a TypeError exception.

Let’s understand with some examples :

Code 1 :

Run

#python Program 
list1 = ['P','r','e','p','s','I','n','s','t','a']

s = "-"
s = s.join(list1)
print(s)

Output:

P-r-e-p-s-I-n-s-t-a

Code 2:

Run

#python Program 
list1 = ['P','r','e','p','s','I','n','s','t','a']
s = ""
s = s.join(list1)
print(s)
