How to Remove Whitespace After Commas in a Text File Using Python

When working with text files in Python, you might encounter a common nuisance: extra whitespace after commas. This can lead to unintended results when processing or analyzing your data. If you've ever loaded a text file and noticed the spaces that appear after your comma-separated values, this guide is for you!

In this guide, we'll take a closer look at how to effectively remove this whitespace using a simple code modification. Let’s dive right in.

The Problem: Extra Spaces After Commas

Consider a sample text file named elemmmm.txt containing the following data:

When we read the contents of this file into Python and split it using commas, we'll end up with entries that still retain unwanted spaces. Here’s how you might typically open the file and split the text:

When executed, this code will access each line and create a list, where each element remains tainted with extra whitespace:

print(list_words[0][0]) produces abc1

print(list_words[0][1]) produces abc2 (with leading space)

print(list_words[0][3]) produces abc abc4

The Solution: Modify the Split Method

The simplest way to clean up your data, removing those pesky spaces, is to adjust the way you split the strings. Instead of just using , as the delimiter, utilize , (comma followed by a space).

Here’s the updated code:

Why This Works:

Removing Whitespace: By using , as a delimiter, Python recognizes the comma followed by a space as the point to split the string. As a result, it eliminates the unnecessary space from each of your entries.

Cleaner Output: When printed, the output will now show:

print(list_words[0][0]) will still return abc1

print(list_words[0][1]) will now return abc2 (without leading space)

The rest of the list will likewise reflect this change, providing a clean, formatted output.

Conclusion

Removing whitespace after commas in your text files can be achieved easily with the right approach in Python. By changing split(',') to split(', '), you can enjoy cleaner data without unnecessary spaces getting in the way of your analysis.

Try this modification in your Python scripts and see how much easier it makes handling your text file data!
