CSV FILE (COMMA SEPERATED VALUE) CSV NOTES LINK :  CSV NOTES - CLICK HERE Writing data to a CSV file involves the following steps: Import the csv module Open the CSV file in write mode ( "w" ) using open() Create the writer object Write the data into the file using the writer object Close the file using close() writerow() Method This method is used to write a single row to a CSV file. It takes a sequence (list or tuple) as its parameter, and writes the items as a comma-separated line in the file. You do not need to add a newline character (\n) — it automatically places the end-of-line marker.     EXAMPLE 1: import csv  # Importing the csv module # CSV file opened using relative path csv_fobj = open("emp.csv", "w")   # Writer object created wtr_obj = csv.writer(csv_fobj) # Record with field heading is written wtr_obj.writerow(["Empno", "Name", "Salary"]) # Records with data are...
