📘 Python Crash Course – Chapter 8: Functions – Exercise 8-16 Solution

Welcome to another solution from Python Crash Course by Eric Matthes.

📝 Exercise 8-16

Task:
Using a program you wrote that has one function in it, store that function in a separate file . Import the function into your main program file, and call the function using each of these approaches:
- import module_name
- from module_name import function_name
- from module_name import function_name as fn
- import module_name as mn
- from module_name import *

✅ Solution Code:

helper_8_15.py


# this help to solve the exercise 8.15 and 8.16

def your_name(first, last):
    full_name = f"{first} {last}"
    return f'Your name is :{full_name}'

exercise_8_16.py


# Importing the function from the helper file
import helper_8_15
print(helper_8_15.your_name("John", "Doe"))

# Importing the function using different approaches
from helper_8_15 import your_name
print(your_name("Jane", "Smith"))


from helper_8_15 import your_name as fn
print(fn("Alice", "Johnson"))

import helper_8_15 as mn
print(mn.your_name("Bob", "Brown"))

from helper_8_15 import *
print(your_name("Charlie", "Davis"))

🧠 Code Explanation:

  1. Import the entire module:

    The statement import helper_8_15 imports the entire module. Functions from the module are accessed using dot notation, such as helper_8_15.your_name().

  2. Import a specific function:

    The statement from helper_8_15 import your_name imports only the your_name function from the module. The function can then be called directly without using dot notation.

  3. Import a function with an alias:

    The statement from helper_8_15 import your_name as fn imports the your_name function and assigns it an alias fn. The function can then be called using the alias, such as fn().

  4. Import the module with an alias:

    The statement import helper_8_15 as mn imports the entire module and assigns it an alias mn. Functions from the module are accessed using the alias, such as mn.your_name().

  5. Import all functions from the module:

    The statement from helper_8_15 import * imports all functions from the module. Functions can then be called directly without using dot notation or aliases.

🔍 Output:


Your name is :John Doe
Your name is :Jane Smith
Your name is :Alice Johnson
Your name is :Bob Brown
Your name is :Charlie Davis
