Python - Remove partial string from dataframe with Pandas

To remove a partial string from a DataFrame in Pandas, you can use the str.replace() method. This method allows you to replace occurrences of a specified string with another string, or remove them by replacing with an empty string. Here's a general approach to do this:

  1. Import Pandas: Make sure you have Pandas imported in your Python environment.
  2. Create or Load DataFrame: Either create a new DataFrame or load one from a file.
  3. Identify the Column: Determine the column from which you want to remove the partial string.
  4. Use str.replace(): Apply the str.replace() method on the selected column to replace the partial string with an empty string.

Here's a sample code to demonstrate this process:

import pandas as pd # Sample DataFrame data = {'Column1': ['Hello World', 'Sample Text', 'Partial String']} df = pd.DataFrame(data) # Partial string to remove partial_string = "Partial " # Remove the partial string from Column1 df['Column1'] = df['Column1'].str.replace(partial_string, '', regex=False) # Display the updated DataFrame print(df)

In this example, the code will remove the partial string "Partial " from each entry in 'Column1'. If you need to use regular expressions for more complex patterns, you can set regex=True. Remember to adjust the column name and the partial string according to your specific DataFrame and requirements.
