Python 写入.txt文件并从.txt文件中删除

我正在尝试创建一个程序，该程序将记录客户的姓名和表号，还可以从.txt文件中删除该预订。到目前为止，写入文件只对我有效一次。

将文件读入合适的结构，然后在每次需要更改时覆盖它。不要对文件对象进行更改。

首先，结尾处缺少一些括号

Tables = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19]
Reserved = []

content = open('C:/Users/amaya/OneDrive/Desktop/CIS 2300/Reservations.txt', 'w+')
def remove(newT, table_reservations):
        newT = []
        for x in range(len(Tables)):
                if x != table_reservations:
                    newT.append(Tables[x-1])
        return newT

def add(Reserved, table_reservations):
    Reserved.append(table_reservations)
    print("Reserved tables (by number):",Reserved)
    return Reserved


print("1-Reserve table")
print("2-Clear reservation")
print("3-Report")
print("0-Exit program")

answer= input("What would you like to do?")   

if answer == '1':

    NAME = input("Name for reservation: ")
    table_reservations = int(input("What table would you like to reserve (1-19)?:  "))

    remove(Tables, table_reservations)
    add(Reserved, table_reservations)
    content.write(NAME)
    content.write(str(table_reservations))
    content.close

if answer == '2':
    content.read
    cancel= input("if you would like to cancel a reservation enter your name and table number: ")
    if cancel == content:
        remove(Reserved, cancel)
    print("Reservation has been canceled.")

if answer == '3':
    print(content)

if answer == '0':
    print("Goodbye!") 

也许您还可以使用csv文件或ans sqlite3数据库和pandas，这将使任务更快、更简单

content.close()
