How to Strip Microseconds from Timestamp Data in Python Using Pandas

When working with timestamps in Python, you might encounter the need to remove microseconds and convert them into a clean string format. This process can seem daunting, especially if you run into errors along the way. In this post, we will help you streamline that task using the powerful Pandas library, addressing a common error and providing you with clear solutions.

The Problem at Hand

You have a list of timestamps and want to strip the microseconds, converting the remaining data into a string format. The original list contains several timestamps, some of which include milliseconds, and your goal is to display them in a more readable format without the microseconds.

Sample Timestamp Data

Here’s the timestamp data you're working with:

The Issue Encountered

You attempted to write a function to convert these timestamps to the desired format, but unfortunately received an error stating:

This occurred because you mistakenly referenced the list as a callable function.

Solution for Stripping Microseconds

Correcting the Function Implementation

To successfully strip the microseconds and convert the timestamps, follow these steps:

Using strftime Method Directly
The simplest way is to utilize the strftime method directly on your Pandas Datetime object. Updating your data as follows ensures clean strings without microseconds:

Correcting the map Function Call
If you prefer using a custom function, make sure to properly define and reference it:

Define your custom function as follows:

This will yield the same output without any errors.

Conclusion

Stripping microseconds from timestamp data and converting it into a string format can be efficiently accomplished with a few straightforward methods in Python using Pandas. Whether you choose to use the strftime method directly on your timestamps or a custom function with the map function, both approaches are valid and effective.

Remember to pay attention to the structure of your code, particularly when defining and calling functions to avoid common errors. With these techniques in your toolkit, you are now better equipped to handle timestamps in your data analysis tasks.
