About the test

The Python online test assesses knowledge of programming in the Python language and commonly used parts of the Python Standard Library. This test requires solving live coding problems in Python.

The assessment includes work-sample tasks such as:

  • Working with Python collections and language constructs.
  • Using proper algorithms and data structures to optimize application performance.
  • Serializing to/from JSON to handle web requests.

A good Python developer needs a solid understanding of the Python programming language and knowledge of its data structures and language constructs to write robust and maintainable code.

Sample public questions

3 min

A university's Office of Admission keeps track of student majors. Each student can have a single major. Below is an example of how their system stores students, majors, and how it manipulates them:

students = [("Allen Anderson", "Computer Science"),
            ("Edgar Einstein", "Engineering"),
            ("Farrah Finn", "Fine Arts")]
def add_new_student(students, name, major):
    students.append((name, major))

def update_student(students, index, name, major):
    students[index] = (name, major)

def find_students_by_name(students, name):
    return [student for student in students if name in student[0]]

def get_all_majors(students):
    return [student[1] for student in students]

What can be concluded from the code snippet above?

10 min

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', '': 'Stan', 'Output.txt': 'Randy'} the group_by_owners function should return {'Randy': ['Input.txt', 'Output.txt'], 'Stan': ['']}.

What others say

Decorative quote

Simple, straight-forward technical testing

TestDome is simple, provides a reasonable (though not extensive) battery of tests to choose from, and doesn't take the candidate an inordinate amount of time. It also simulates working pressure with the time limits.
