Python String join() Method

The join() method returns a string, which is the concatenation of the string (on which it is called) with the string elements of the specified iterable as an argument.

Syntax:

str.join(iterable)

Parameters:

iterable: (Required) An iterable object such as list, tuple, string, set, dict.

Return Value:

Returns a string.

The following example demonstrates the join() method.

Example: join()

emp = {'Steve': 1, 'Bill': 2, 'Ravi': 3 }
print('>-'.join(emp))

emp = {1:'Steve', 2:'Bill', 3:'Ravi' } # raise an error
print('&gt;-'.join(emp))

Output

Steve>-Bill>-Ravi TypeError: sequence item 0: expected str instance, int found
