String Join Method

The str.join(iterable) method is used to join all elements in an iterable with a specified string str. If the iterable contains any non-string values, it raises a TypeError exception.

iterable: All iterables of string. Could a list of strings, tuple of string or even a plain string.

Examples

1. Join a ist of strings with ":"

print( ":".join(["freeCodeCamp", "is", "fun"]))

Output

freeCodeCamp:is:fun

2. Join a tuple of strings with " and "

print(" and ".join(("A", "B", "C")))

Output

A and B and C

3. Insert a " " after every character in a string

print(" ".join("freeCodeCamp"))

Output:

f r e e C o d e C a m p

4. Joining with empty string.

list1 = ['p','r','o','g','r','a','m']  
print("".join(list1))

Output:

program

5. Joining with sets.

test =  {'2', '1', '3'}
s = ', '
print(s.join(test))

Output:

2, 3, 1
