Question

我正在用python创建一个日历系统，该系统创建一个带有描述作为其内容的文件。该文件将被放置在目录中，文件的日期相同，以便检测重叠事件。

创建后，我曾尝试使用Shutil将文件移入，但是我没有运气，也没有将目录设置为新文件夹。（为不好的编码而道歉，我是python的新手，还不太了解格式设置和解决这些逻辑问题的最佳方法）。

def newEvent():  # Creates new event
    directory = input("Input the calender directory. This can be changed in the settings: ")
    pattern = "^(3[01]|[12][0-9]|0[1-9]).(1[0-2]|0[1-9]).[0-9]{4}$"  # DD.MM.YYY Pattern
    eventName = input("Please enter the name of the event: ")
    print("'" + eventName + "'" + " successfully Registered.")
    time.sleep(0.5)
    eventDate = input("Please enter the date of the event in the 'DD.MM.YYYY' format: ")
    time.sleep(0.5)
    if re.match(pattern, eventDate):  # Matches pattern with eventDate
        print(eventName + " successfully Registered on the " + eventDate)
        time.sleep(0.5)
        description = input("Please input a description for the event: ")
        time.sleep(0.5)


        if os.path.exists(re.sub('\.', '', eventDate)):
            fileName = str(re.sub('\.', '', eventDate)) + "/" + eventDate + " - " + eventName + ".txt"  # Creates the file name

            newFile = open(str(fileName), "w+")  # Creates the file
            newFile.write(description)  # Adds description
            newFile.close()
        else:
            newDir = os.mkdir((re.sub('\.', '', eventDate)))  # Creates new directory named the event date minus the "."
            fileName = "/" + eventDate + " - " + eventName + ".txt"

            newFile = open(str(directory) + (fileName), "w+")
            newFile.write(description)
            newFile.close()
            shutil.move(str(newFile), str(newDir))
        print("Your event: " + str(eventName) + " taking place on the " + eventDate + " has been registered. Returning to menu.")
        time.sleep(0.5)
        menu()
    else:
        print("Date not valid, returning to 'New Event'.")
        time.sleep(0.5)
        newEvent()

我希望代码将newFile移到创建的目录中，但是它将在.py文件的目录中创建文件。

问题在于路径的定义。另外，您还尝试移动newFile（它是一个TextWrapper实例），而不是路径字符串或类似路径的对象（但是您将其转换为字符串，因此终端不会给您正确的错误消息）

我建议您使用os.path.join创建路径：它更干净，更不易出错并且具有多平台功能，因此您不必担心Windows和linux路径分隔符（\或/）之间的冲突。

此外，您可以使用正确的绝对路径直接定义文件名，从而不必移动任何内容

def newEvent():  # Creates new event
    directory = input("Input the calender directory. This can be changed in the settings: ")
    pattern = "^(3[01]|[12][0-9]|0[1-9]).(1[0-2]|0[1-9]).[0-9]{4}$"  # DD.MM.YYY Pattern
    eventName = input("Please enter the name of the event: ")
    print("'" + eventName + "'" + " successfully Registered.")
    time.sleep(0.5)
    eventDate = input("Please enter the date of the event in the 'DD.MM.YYYY' format: ")
    time.sleep(0.5)
    if re.match(pattern, eventDate):  # Matches pattern with eventDate
        print(eventName + " successfully Registered on the " + eventDate)
        time.sleep(0.5)
        description = input("Please input a description for the event: ")
        time.sleep(0.5)

        event_dir = os.path.join(directory, re.sub('\.', '', eventDate))
        fileName = os.path.join(directory, event_dir, eventDate + " - " + eventName + ".txt")  # Creates the file name
        if os.path.exists(event_dir):
            newFile = open(str(fileName), "w+")  # Creates the file
            newFile.write(description)  # Adds description
            newFile.close()
        else:
            newDir = os.mkdir(event_dir)  # Creates new directory named the event date minus the "."
            newFile = open(fileName, "w+")
            newFile.write(description)
            newFile.close()
            # shutil.move(str(fileName), str(newDir))
        print("Your event: " + str(eventName) + " taking place on the " + eventDate + " has been registered. Returning to menu.")
        time.sleep(0.5)
        menu()
    else:
        print("Date not valid, returning to 'New Event'.")
        time.sleep(0.5)
        newEvent()

如何将创建的文件移动到我刚才创建的目录中？
