Python's str.join(~) method concatenates the elements of an iterable and returns the resultant string.

Parameters

1. iterable | iterable

The iterable whose elements are to be concatenated.

Return value

A concatenated string of elements of the iterable.

Examples

Basic usage

To concatenate the elements of iterable x using a comma separator:

x = ('a', 'b', 'c')
separator = ','
separator.join(x)
'a,b,c'

Note that the elements in tuple x are concatenated with separator ',' in between each item.

TypeError

To concatenate the elements of iterable x using a comma separator:

x = {1, 2, 3}
separator = ','
print(separator.join(x))
TypeError: sequence item 0: expected str instance, int found

A TypeError is raised as there are non-string values in the iterable x.

Usage with dictionaries

The join(~) method will concatenate the keys of a dictionary rather than values:

cars = {"Ferrari": "red", "Porsche": "silver", "Bentley": "black"}
separator = " > "
separator.join(cars)
'Ferrari > Porsche > Bentley'
