Why standard library modules are used in Python - See It in Action

Why standard library modules are used

📖 Scenario: Imagine you want to build a small program that works with dates and times, but you don't want to write all the code from scratch. Python has many ready-made tools inside its standard library that help you do common tasks easily.

🎯 Goal: You will learn why using Python's standard library modules is helpful by writing a simple program that uses the datetime module to get the current date and time.

📋 What You'll Learn

Create a variable using the datetime module

Use a function from the datetime module to get the current date and time

Print the current date and time

💡 Why This Matters

🌍 Real World

Many programs need to work with dates, times, numbers, or files. Using standard library modules helps programmers do these tasks easily and correctly.

💼 Career

Knowing how to use standard library modules is a basic skill for any Python programmer. It shows you can write efficient and reliable code.

1

Import the datetime module

Write the line to import the datetime module so you can use its functions.

Python

# Import the datetime module
# Your code here

Need a hint?

Use the import keyword followed by the module name datetime.

2

Get the current date and time

Create a variable called now and set it to the current date and time using datetime.datetime.now().

Python

import datetime
# Create a variable now with current date and time
# Your code here

Need a hint?

Use datetime.datetime.now() to get the current date and time.

3

Print the current date and time

Write a print statement to display the value of the variable now.

Python

import datetime
now = datetime.datetime.now()
# Print the current date and time
# Your code here

Need a hint?

Use print(now) to show the current date and time on the screen.

4

Run the program and see the output

Run the program to see the current date and time printed on the screen.

Python

import datetime
now = datetime.datetime.now()
print(now)
# Run the program to see the output

Need a hint?

The output will show the current date and time, starting with the year like 2024-...
