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.
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?
Implement a group_by_owners function that:
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']}.
