The Python online test assesses candidates' knowledge of programming in the Python language and understanding of its native data structures.

It's an ideal test for pre-employment screening. A good Python developer needs to be able not only to solve problems using Python as the programming language but also be familiar with Python native data structures and language constructs.

This online test requires candidates to solve coding problems in Python as well as to find and fix bugs in a Python program.

Python Language Public

Implement a group_by_owners function that:

  • Accepts a dictionary containing the file owner name for each file name.
  • Returns a dictionary containing a list of file names for each owner name, in any order.

For example, for dictionary {'Input.txt': 'Randy', 'Code.py': 'Stan', 'Output.txt': 'Randy'} the group_by_owners function should return {'Randy': ['Input.txt', 'Output.txt'], 'Stan': ['Code.py']}.

Python List Public

Implement the unique_names method. When passed two lists of names, it will return a list containing the names that appear in either or both lists. The returned list should have no duplicates.

For example, calling unique_names(['Ava', 'Emma', 'Olivia'], ['Olivia', 'Sophia', 'Emma']) should return a list containing Ava, Emma, Olivia, and Sophia in any order.

As part of a data processing pipeline, complete the implementation of the pipeline method:

  • The method should accept a variable number of functions, and it should return a new function that accepts one parameter arg.
  • The returned function should call the first function in the pipeline with the parameter arg, and call the second function with the result of the first function.
  • The returned function should continue calling each function in the pipeline in order, following the same pattern, and return the value from the last function.

For example, pipeline(lambda x: x * 3, lambda x: x + 1, lambda x: x / 2) then calling the returned function with 3 should return 5.0.
