add

add(element)

Adds an element to the Enumerable collection. This is not an executing function.

Parameters

element - The element to add to the Enumerable collection.

Returns

An Enumerable instance with the added element.

Note

Please note that this method uses the concat method to add the element to the Enumerable. The concat method tries to enforce some crude type checking to ensure that the same type of elements are added to the Enumerable that could lead to linear time performance whenever add is called. For example,

var students = Enumerable([21234, 76543]).add(23456).add(7893)

would give O(2n) where n = 2 performance.

I am currently rethinking this strategy because of the performance hit and because type checking is not a necessity in Python.

Example

from py_linq import Enumerable

students = Enumerable([{ 'name': 'Joe Smith', 'marks': [80, 90, 75]}, { 'name': 'Joanne Smith', 'marks': [67, 89, 91]}])
students.add({'name': 'John Deere', 'marks': [55, 56, 57]}) 
# students is now:
[
 { 'name': 'Joe Smith', 'marks': [80, 90, 75]},
 { 'name': 'Joanne Smith', 'marks': [67, 89, 91]},
 {'name': 'John Deere', 'marks': [55, 56, 57]}
]
