Module search path in Python - Mini Project: Build & Apply

Explore Python Module Search Path

📖 Scenario: You want to understand where Python looks for modules when you try to import them. This helps you know how Python finds the code you want to use.

🎯 Goal: Build a small Python program that shows the list of folders Python searches for modules. This list is called the module search path.

📋 What You'll Learn

Create a variable named import_sys that imports the sys module

Create a variable named module_path that stores the sys.path list

Use a for loop with variable path to go through module_path

Print each path on its own line

💡 Why This Matters

🌍 Real World

Knowing the module search path helps you debug import errors and manage where Python finds your code.

💼 Career

Developers often need to understand module paths to configure environments and fix issues with missing modules.

1

Import the sys module

Write import_sys = __import__('sys') to import the Python system module and assign it to a variable called import_sys.

Python

# Import the sys module and assign it to import_sys
# Your code here

Need a hint?

Use the __import__('sys') function to import the sys module and assign it to import_sys.

2

Get the module search path list

Create a variable called module_path and set it to import_sys.path to get the list of folders Python searches for modules.

Python

import_sys = __import__('sys')
# Create module_path variable to store import_sys.path
# Your code here

Need a hint?

Use module_path = import_sys.path to get the list of module search paths.

3

Loop through the module search path

Use a for loop with variable path to go through each item in module_path.

Python

import_sys = __import__('sys')
module_path = import_sys.path
# Use a for loop with variable path to iterate over module_path
# Your code here

Need a hint?

Write for path in module_path: and inside the loop use print(path) to show each folder.

4

Print the module search path

Run the program to print each folder in the Python module search path, one per line.

Python

import_sys = __import__('sys')
module_path = import_sys.path
for path in module_path:
    print(path)
# Run the program to see the output

Need a hint?

Just run the program. It will print the list of folders Python searches for modules.
