您如何在python中搜索CSV文件？

Question

I am trying to create a CSV file with two headings:

Name Score

and then underneath input the name and score. this is so that if the program was run again it would find that name and score was already implemented and not run it again and instead skip that process and just proceed to enter the name and score. here is my current code below. any advice or help i greatly welcome:

filename = Class_Name + ".csv" #have already defined filename earlier

def excel_search():
    with open(filename, 'rb') as file_data:
        reader = csv.DictReader(file_data, ("Score"))
        if i not in reader:
            with open(filename, 'w', newline='') as f:
                data= "Name","Score"
                f.write(str(data))



excel_search()
    with open(filename, 'a', newline='') as f:
        f.writerows('\n'[Student_Name],[User_Score]) # have defined userscore and studentname earlier

Not sure if this is exactly what you are going for but it may work for your purpose.

import csv
search=input('Enter string to search: ')
stock=open ('FileName.csv', 'wb')
reader=csv.reader(FileName)
for row in reader:
    for field in row:
        if field==code:
            print('Record found! \n')
            print('Name: '+row[0])
            print('Score: '+row[1])

The print('Name: '+row[0]) should print the name and the print('Score: '+row[1]) should print the player's score.
