使用 Python 更新 csv 文件的列值

Question

我的问题是：客户选择酒店后，请他提供相同的反馈和根据数据更新 rating.csv 文件 received.And 我如何更新给定反馈给这些文件。

这是我到目前为止尝试过的：

h_id=str(input("Enter Hotel_Id:"))
with open("rating.csv", "r") as fb:
    csvreader = csv.reader(fb, delimiter=",")
    for row in csvreader:
        if h_id in row[0]:
           print("Hotel Booked Sucessfully")
           f_back=float(input("Please Give Feedback of Hotel you selected outoff 5:"))

Answer 1

我会这样做：

import pandas as pd

#read the hotels table
hotels = pd.read_csv("rating.csv")

h_id=str(input("Enter Hotel_Id:"))
f_back=float(input("Please Give Feedback of Hotel you selected outoff 5:"))

hotels.loc[hotels.Hotel == h_id,"no_of_feedback" ] = hotels.loc[hotels.Hotel == h_id,"no_of_feedback" ]+1
hotels.loc[hotels.Hotel == h_id,"Feedback" ] = f_back

#store updated table
hotels.to_csv("rating.csv")
