如何从 txt 中排序数据？

Question

我需要按时间顺序对这些数据进行排序，希望按日期排序，然后按时间排序，但现在我只想按日期排序...信息在 TXT 文件中：

2022/5/10 at 10 the client Mari has appointment with the Dra. Windrunner
2022/1/5 at 2 the client Ian has appointment with the Dr. Stark
2022/1/4 at 10 the client Amy has appointment with the Dra. Windrunner
2022/1/5 at 2 the client Josh has appointment with the Dr. Stark
2022/2/22 at 5 the client Mike has appointment with the Dr. Pool
2022/2/22 at 4 the client Pedro has appointment with the Dr. Stark

这是我现在的代码：

Docs = ("Dr. Stark", "Dra. Windrunner", "Dr. Pool")
x = 0
loop = False

DocsConverter = {
    "0" : "Dr. Stark",
    "1" : "Dra. Windrunner",
    "2" : "Dr. Pool",
    "dr. stark": "Dr. Stark",
    "dra. windrunner" : "Dra. Windrunner",
    "dr. pool" : "Dr. Pool",
    "stark" : "Dr. Stark",
    "windrunner" : "Dra. Windrunner",
    "pool" : "Dr. Pool"
}

with open("appointment_hospital.txt", "a") as file_ap:
    pass


def menu():
    option = input("select a option 1. new appointment 2.show appointments 3. Exit: (1/2/3)\n")
    if option == "1":
        new_appointment()
    elif option == "2":
        print_appointments()
    elif option == "3":
        file_ap.close()
        exit()
    else:
        print("Wrong option")


def new_appointment():
    global x
    name_client = input("Enter the name of the client:\n")
    schedule_day = input("Enter the year, month and the day of the appointment:(Y/M/D)\n")
    schedule_time= input("Enter at what hour is the appointment:\n")
    while x != 3:
        print(f"{Docs[x]}, id = {x}")
        x += 1
    x = 0
    which_doc = input("Enter the name or the Id of the doctor: ")
    appointment_info = f"{schedule_day} at {schedule_time} the client {name_client} has appointment with the " \
                       f"{DocsConverter.get(which_doc)}\n"
    with open("appointment_hospital.txt", "a") as file:
        file.write(appointment_info)

#this is where i tried to sort the information in the txt
def print_appointments():
    with open("appointment_hospital.txt", "r") as file:
        lines_appointments = []
        for line in file:
            temp = line.split()
            for i in temp:
                lines_appointments.append(i)
        lines_appointments.sort()
        with open("sort_appointments", "w") as sort_file:
            for i in lines_appointments:
                sort_file.writelines(i)
                sort_file.writelines(" ")
            sort_file.close()
    with open("sort_appointments", "w") as sort_file:
        read_appointments = sort_file.read()
        print(read_appointments)


while not loop:
    menu()

所以在 def print_appointments(): 中，我尝试对数据进行排序，这是我最后一次尝试，None 我所做的那些给了我一个适度的积极结果。

你有一些错误：

无文件扩展名open("sort_appointments"
按日期排序剩余按行拆分文件
将列表写入文件时，需要打开后追加“a”
读取文件时，必须输入字母“r”

def print_appointments():
    with open("appointment_hospital.txt", "r") as file:
        lines_appointments = []
        for line in file:
            lines_appointments.append(line)
    lines_appointments.sort()

    with open("sort_appointments.txt", "a") as sort_file:
            sort_file.writelines(lines_appointments)


    with open("sort_appointments.txt", "r") as sort_file:
        read_appointments = sort_file.read()
        print(read_appointments)



print_appointments()
