Python Date and Time Functions - Check out practical examples and expert tips to enhance your skills in time handling for your Python projects. | ProjectPro

Have you tried to change data time or calculate some statistics from date time stamps? This tutorial will walk you through practical examples, share valuable tips, and help you understand how to integrate time-related features into your Python projects. So, let's get started! 

What are Python Date Functions? 

Python provides a comprehensive set of date and time functions through its built-in datetime module. Date functions are essential for various applications, ranging from simple data manipulations to more complex tasks like handling time series data in machine learning.

Some standard Python date functions include:

  • datetime.now(): Retrieves the current date and time.

  • strptime(): Parses a string into a datetime object based on a specified format.

  • strftime(): Formats a datetime object into a string with a specified format.

  • timedelta(): Represents the difference between two dates or times.

How do you Deal with Date functions in Python? 

Dealing with date functions in Python involves various operations such as creating, formatting, parsing, and manipulating dates. The datetime module is crucial for these tasks. Developers can create datetime objects, convert them to strings, extract components like year or month, and perform arithmetic operations with timedelta.

Here's a basic overview of how to deal with date functions in Python, along with an example:

How to Handle Date in Machine Learning?

In machine learning, handling dates involves incorporating them into models and dealing with various time-related challenges. Check out the key strategies below :-

  1. Feature Engineering

Create new features from dates, such as day of the week, month, and year, to provide more context to your machine learning models.

  1. Time-based Splits

Consider time-based splits when splitting your dataset into training and testing sets to ensure the model is evaluated on future data.

  1. Handling Time Series Data

For time series data, use specialized libraries like Pandas and statsmodels for analysis, and consider models like ARIMA or Prophet for forecasting.

What are Python Timer Functions? 

Python timer functions are crucial in executing tasks at specific intervals or after a certain delay. The time module in Python provides a simple and effective way to incorporate timers into your programs.

Python Timer Functions

Example - Python Datetime Function 

Step 1 - Import the library

    from datetime import datetime

    from datetime import timedelta

We have imported datetime and timedelta, which will be needed for the dataset.

Step 2 - Setting up the Data

We have used the current datetime for this snippet.   

    now = datetime.now()

    print(now)

Step 3 - Dealing with Date Time

Here, we will be using different functions that we can use on date time.

  1. Calculating Current Year

 print(now.year)

  1. Calculating current month

print(now.month)

  1. Calculating current day

print(now.day)

  1. Calculating current hour

print(now.hour)

  1. Calculating current minute

print(now.minute)

  1. Calculating difference between two days

delta = datetime(2011, 1, 7) - datetime(2011, 1, 6)

print(delta.days)

  1. Calculating difference in seconds

print(delta.seconds)

  1. Creating a datetime

start = datetime(2018, 1, 7)

  1. Adding twelve days to the time

print(start + timedelta(12))

So the output comes as:

2020-10-16 01:50:34.441904

2020

1 day, 0:00:00
