But writerows and writerow just and an another table without clearing the first content(unLike in txt files)

here is the class and the program

import csv as c

class Table:

    def __init__(self,File):
        self.file = File
        self.ro = c.reader(File)
        self.wo = c.writer(File)
        self.table_list = []
        for row in self.ro:
            self.table_list.append(row)

    def get_table_list(self):
        . . .

    def visualize_table(self):
        . . . 

    def get_number_of_column(self):
        . . .

    def get_number_of_row(self):
        . . .

    def get_index(self,item_entry,item):
        . . .
        
    def change(self,item_entry,item,to_item):
        . . .

    def write_table(self):
        self.wo.writerows(self.table_list)

file = open("test.csv","r+",newline="")

table = Table(file)

table.change("name","tarun","aditya")

table.write_table()

file.close()

before write_csv function

after write_csv fuction

As you can see this is not what I want

Answer

You can use the truncate method.

>>> file = open("test.csv","r+",newline="")
>>> file.truncate(0) # Clears file
