Consider the files a.py, b.py, c.py, and main.py described below. What are the required imports for each file to make executing main.py work?

Explain what it means to modularize your code.

How can you import a module into your Python program?

What's wrong with the following code?

Consider the following code:

# user.py
class User:
    def __init__(self, first_name, last_name):
        self.first_name = first_name
        self.last_name = last_name

    def get_display_name(self):
        return self.first_name + " " + self.last_name

--

# main.py
from user import User

user_one = User("John", "Doe")
print(user_one.get_display_name())

What happens when user.py is executed?

The provided code sets the variable a_date equal to the result of dt.utcnow(), where dt an alias of datetime.datetime. Without modifying the code, add the appropriate import statement to make this code work.

What is documentation?

Write a function date_compare(d1, d2) that compares two datetime.datetime objects (d1 and d2) and returns "d1 is later than d2", "d1 and d2 are the same", or "d2 is later than d1", depending on the values of d1 and d2.

If you find multiple third-party modules that have similar purposes, how can you decide which one to use?

Explain what versioning is with respect to Python modules. Why can versioning cause issues in Python programs?

List some example third-party modules in Python.
