Проблемы печати в CSV на Python

Question

Для работы я создал очень простой пользовательский интерфейс, который при нажатии btn генерирует пользователей с помощью веб-службы.Я хочу быть в состоянии записать эти данные пользователя в CSV, но я изо всех сил.Может ли кто-нибудь помочь, пожалуйста?

Я прокомментировал в своем коде, где возникает проблема

#Needs to import user_creation to call and write_to_file to close file
import user_creation 
import write_to_file
from tkinter import *
from tkinter.ttk import *
import csv

#commented these lines out and added into clicked() within the GUI
#amountOfUsers = input("How many users would you like to create? ")
#inputGroupId = input("What group do you want to add this/these user/s to? ")
#Call generateUser in user_creation to generate the codes, it will then call write_to_file 
#user_creation.generateUser(amountOfUsers, inputGroupId)


window = Tk()

window.title("RR Testing Tool") #title of window
window.configure(background="gray85") #background colour

window.geometry('500x150') #size of window

#text label beside group name textbox
group_name_lbl = Label(window, text="Enter a Group Name")
group_name_lbl.grid(column=0, row=0)
group_name_lbl.configure(background="gray85")

#group name text box
txtbox = Entry(window,width=20)
txtbox.grid(column=1, row=0)

#text label beside combo box
num_of_users_lbl = Label(window, text="Select the Number of Users to Create")
num_of_users_lbl.grid(column=0, row=4)

#combo box with predefined values for number of users 1-15
combo = Combobox(window)
combo['values']= (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15)
combo.current(0) #set the selected item
combo.grid(column=1, row=4)

#this is called when the button is clicked
def clicked():

    inputGroupId = txtbox.get()

    #combo_value = combo.get()
    amountOfUsers = combo.get()

    #User the date and time from Write to File to name the file i am opening
    with open('date_time_filename_string', 'w', newline='') as f:
        thewriter = csv.writer(f)
    #Write the title of the csv before you start filling the body
    thewriter.writerow(['Activation Code', 'Mobile Scope Token','DeviceId','UserId ','GroupID'])   

    user_creation.generateUser(amountOfUsers, inputGroupId)    

    f.close()
    #group_name_lbl.configure(text= inputGroupId)

#button
submit_btn = Button(window, text="Create!!", command=clicked)
submit_btn.grid(column=1, row=10)


window.mainloop()

import datetime

date_time_filename_string = currentDate.strftime("%Y-%m-%d-%H%M%S") + ".csv"

    #Write to file - will be updated to CSV

    #f.write('UserId = ' + userId + '\n')
    #f.write('GroupId = ' + inputGroupId + '\n') 
    #f.write('\n')
    #Populate Body of CSV

Я получаю ошибку:

'Неопределенная переменная' TheWriter 'thewriter.writerow ([код активации, mobile_scope_token, идентификатор устройства, идентификатор пользователя, идентификатор ввода]]

Существует дваразные методы / модули, основной и метод записи в файл, я думаю, проблема в том, что я не импортирую что-то правильно, но я действительно не уверен.Может кто-нибудь, пожалуйста, помогите

Исправлена ​​эта ошибка, но есть еще одна сейчас.«Операция ввода-вывода для закрытого файла»

Answer 1

Вы закрываете свой файл перед записью в него:

with open('date_time_filename_string', 'w', newline='') as f:
    thewriter = csv.writer(f)  # !!! file is closed after this line
#Write the title of the csv before you start filling the body
thewriter.writerow(['Activation Code', 'Mobile Scope Token','DeviceId','UserId ','GroupID'])  

Использование оператора with для файла закрывает в конце блока.Это означает, что thewriter имеет только закрытый файл для записи после блока.

Убедитесь, что все строки, которые инициируют запись в f, являются частью блока with:

with open('date_time_filename_string', 'w', newline='') as f:
    thewriter = csv.writer(f)
    #Write the title of the csv before you start filling the body
    thewriter.writerow(['Activation Code', 'Mobile Scope Token','DeviceId','UserId ','GroupID'])
