我是 python 新手，在將數據輸出到 csv 文件時遇到了一些問題。腳本運行但文件是空白的，創建時沒有數據。#!/usr/bin/env python3import osimport smtplibimport csvos.system('clear')class CreateList(object): def add_items(self): shop_list = [] print("Lets create a shopping list for you..\n") print("Please enter DONE when you have all the items needed for your shopping list.") while True: add_item = input("> ") if add_item == 'DONE': break shop_list.append(add_item) print("Here is your current shopping list:") csv = open('shoplist.csv', 'w') for item in shop_list: print(item) csv.write(item + '\n') csv.close()c = CreateList()c.add_items()

您可能只是有一些額外的縮進。這是相同的腳本，但在第 19 和 20 行刪除了一些縮進。
#!/usr/bin/env python3
import os
import smtplib
import csv
os.system('clear')
class CreateList(object):
def add_items(self):
shop_list = []
print("Lets create a shopping list for you..\n")
print("Please enter DONE when you have all the items needed for your shopping list.")
while True:
add_item = input("> ")
if add_item == 'DONE':
break
shop_list.append(add_item)
print("Here is your current shopping list:")
csv = open('shoplist.csv', 'w')
for item in shop_list:
print(item)
csv.write(item + '\n')
csv.close()
c = CreateList()
c.add_items()
開滿天機

有一個else失蹤。您input沒有附加任何內容shop_list，因此沒有任何內容寫入文件。
import os
import smtplib
import csv
os.system('clear')
class CreateList(object):
def add_items(self):
shop_list = []
print("Lets create a shopping list for you..\n")
print("Please enter DONE when you have all the items needed for your shopping list.")
while True:
add_item = input("> ")
if add_item == 'DONE':
break
else: # <<< missing
shop_list.append(add_item)
print("Here is your current shopping list:")
csv = open('shoplist.csv', 'w')
for item in shop_list:
print(item)
csv.write(item + '\n')
csv.close()
c = CreateList()
c.add_items()
