Python String join() method example

In this source code example, we will demonstrate how to use the Python String join() method to concatenate strings in an iterable into one string.

Basically, we use the join() method to concatenate multiple strings in an iterable into one string.

Python String join() method

The string join() method returns a string which is the concatenation of strings in an iterable such as a tuple, a list, a dictionary, and a set.

The following shows the syntax of the join() method:

str.join(iterable)

Python String join() method examples

The following example uses the string join() method to concatenate a tuple of strings without a separator:

name = ('source', 'code', 'examples')
fullName = ''.join(name)
print(fullName)

Output:

sourcecodeexamples

The following example uses the string join() method with the comma separator (,):

name = ('source', 'code', 'examples')
fullName = ','.join(name)
print(fullName)

Output:

source,code,examples
