Csv - Specify date in ouput file name using python

To specify a date in the output file name when working with CSV files in Python, you can use the datetime module to get the current date and time, and then format it as part of the file name. Here's an example:

import csv from datetime import datetime # Get the current date and time current_date = datetime.now().strftime("%Y-%m-%d") # Example data to write to CSV data = [ ["John", "Doe", 30], ["Jane", "Smith", 25], ["Bob", "Brown", 35] ] # Specify the file name with the current date output_file = f"data_{current_date}.csv" # Write data to CSV with open(output_file, mode='w', newline='') as file: writer = csv.writer(file) writer.writerows(data) print(f"Data written to {output_file}")

In this example:

  • We import the csv module for working with CSV files and the datetime module to get the current date and time.
  • We use datetime.now().strftime("%Y-%m-%d") to get the current date in the format "YYYY-MM-DD".
  • We specify the file name using f-strings, which allow us to embed variables within strings. Here, current_date is embedded in the file name.
  • We then write some example data to a CSV file with the specified file name.
  • Finally, we print a message indicating the file to which the data was written.

This will create a CSV file with a name like "data_2024-05-08.csv", where "2024-05-08" is replaced with the current date.
