Adding a datetime stamp to python print

When working with Python, it can be useful to add a datetime stamp to the print statements in order to track when certain events occur. This can be particularly helpful when debugging or monitoring the execution of a program. In this article, we will explore three different ways to add a datetime stamp to Python print statements.

Option 1: Using the datetime module

The first option involves using the datetime module in Python to retrieve the current date and time. We can then format this information and concatenate it with the desired message before printing it to the console.

import datetime

message = "Hello, world!"
timestamp = datetime.datetime.now().strftime("%Y-%m-%d %H:%M:%S")
print(f"[{timestamp}] {message}")

This code snippet imports the datetime module and assigns the desired message to the variable “message”. The current date and time are retrieved using the now() method from the datetime class. The strftime() method is then used to format the timestamp according to the desired format (“%Y-%m-%d %H:%M:%S” in this case). Finally, the timestamp and message are concatenated using an f-string and printed to the console.

Option 2: Creating a custom print function

Another approach is to create a custom print function that automatically adds a datetime stamp to the message. This can be achieved by defining a new function that wraps around the built-in print function and adds the timestamp before calling the original print function.

import datetime

def print_with_timestamp(message):
    timestamp = datetime.datetime.now().strftime("%Y-%m-%d %H:%M:%S")
    print(f"[{timestamp}] {message}")

message = "Hello, world!"
print_with_timestamp(message)

In this code snippet, we define a new function called “print_with_timestamp” that takes a message as input. Inside the function, we retrieve the current timestamp using the same approach as in option 1. We then concatenate the timestamp and message using an f-string and call the original print function to display the message with the timestamp.

Option 3: Using a decorator

The third option involves using a decorator to modify the behavior of the print function. Decorators allow us to add functionality to an existing function without modifying its source code. In this case, we can create a decorator that adds a datetime stamp to the message before calling the original print function.

import datetime

def add_timestamp_to_print(func):
    def wrapper(message):
        timestamp = datetime.datetime.now().strftime("%Y-%m-%d %H:%M:%S")
        func(f"[{timestamp}] {message}")
    return wrapper

@add_timestamp_to_print
def print_with_timestamp(message):
    print(message)

message = "Hello, world!"
print_with_timestamp(message)

In this code snippet, we define a decorator function called “add_timestamp_to_print” that takes a function as input. Inside the decorator, we define a wrapper function that adds the timestamp to the message before calling the original function. The wrapper function is then returned by the decorator. We can apply the decorator to the print_with_timestamp function using the “@” syntax. When we call print_with_timestamp, the decorator will automatically add the timestamp to the message before printing it.

After exploring these three options, it is clear that the best approach depends on the specific requirements of the project. Option 1 is the simplest and most straightforward solution, but it requires modifying each print statement individually. Option 2 provides a more reusable solution by creating a custom print function, but it still requires modifying the code where print statements are used. Option 3 offers the most flexible solution by using a decorator, but it requires more advanced knowledge of Python and may not be suitable for all scenarios. Ultimately, the choice between these options should be based on the specific needs and constraints of the project.
