Deleting rows with Python in a CSV file

Title: Deleting Rows in a CSV File with Python: A Step-by-Step Tutorial
Introduction:
CSV (Comma-Separated Values) files are a popular format for storing tabular data. In this tutorial, we will explore how to delete rows from a CSV file using Python. We'll use the csv module, which is part of the Python standard library, to read, modify, and write CSV files.
Prerequisites:
Step 1: Import the necessary modules
Step 2: Open the CSV file
Step 3: Create a new CSV file for output
We'll open a new CSV file in write mode, which will be used to write the modified data without the rows to be deleted.
Step 4: Iterate through the rows and delete specific rows
You can use a loop to iterate through the rows of the CSV file. Identify the rows you want to delete based on a condition and write the remaining rows to the output CSV file.
For example, let's say we want to delete rows where the value in the second column (index 1) is 'John'.
Step 5: Complete the code and test
Finally, complete the code by closing both the input and output files.
Remember to customize the condition inside the loop based on your specific requirements for deleting rows. This example assumes you want to delete rows where the value in the second column is 'John'.
Save the script and run it using a Python interpreter. Verify the output CSV file to ensure that the specified rows have been deleted.
Conclusion:
This tutorial has provided a basic guide on how to delete rows from a CSV file using Python. You can modify the code according to your specific needs and criteria for row deletion. The csv module in Python provides a convenient way to work with CSV files, making data manipulation tasks efficient and straightforward.
