How to Convert a String Date to Unix Time in Python

When working with date and time in Python, you may encounter situations where you need to convert a string representation of a date into a Unix time format. Unix time, also known as timestamp, is a way to track time as a running total of seconds since January 1, 1970. It’s widely used in programming and databases for its simplicity and ease of use.

In this guide, we will explore how to convert a string date to Unix time using Python while addressing a common error that you might encounter in the process.

The Problem: Converting a Date String to Unix Time

Let's say you have a date string like "2018-06-29 08:15:27" and you want to convert this into a Unix timestamp. You might write a script in Python similar to the following:

However, when you run the script, you encounter the following error:

Understanding the Error

The error message indicates that there’s a problem with how the timestamp method is being accessed. The key takeaway here is that timestamp is not a function of the datetime module but of the datetime object itself. This means that we need to call timestamp on an instance of the datetime class, rather than trying to access it through the datetime module.

The Solution: Correctly Accessing the timestamp Method

To properly convert the string date to Unix time, you need to call the timestamp method on the date_time_obj instance you've created. Here are two ways to do that:

Method 1: Calling timestamp() on the date_time_obj

Simply call the timestamp method directly on your date_time_obj like this:

Method 2: Using datetime.datetime.timestamp()

Alternatively, you can specify the class when calling timestamp, which is also valid, though less common. Here’s how you can do it:

Final Script Example

Combining everything, your final script should look like this:

Conclusion

Converting a string date to Unix time in Python is a straightforward task if you know how to correctly call the necessary methods. Always remember that the timestamp method belongs to the datetime object and not the datetime module itself. By following the outlined steps, you can easily avoid the common pitfalls associated with this conversion.

Happy coding!
