Handling Column Values with Multiple Separators in Pandas DataFrames
Splitting Column Values Using Multiple Separators in Python with Pandas ====================================================================
When working with CSV files and pandas DataFrames, it’s common to encounter column values that are comma-separated, but may also include spaces around the commas. This can lead to issues when trying to split these values using the split() method or other string manipulation functions. In this article, we’ll explore how to handle such cases using multiple separators.
Understanding the Problem The issue at hand is that when you try to split a comma-separated string in Python using the split() method, it only splits on the specified separator (in this case, a comma), without considering spaces around the commas.
