Question

我试图让这段代码询问用户的详细信息，然后用逗号分隔字符串将它们保存到.txt文件中。每次运行代码时我都需要写一个新行，但是添加＆＃34; / n＆＃34;在字符串的末尾但是它在同一行上提供了所有用户的数据。有什么帮助吗？

print ("enter your name, age, and year group and password")
while True:
    reg_name = input("Name:"))
    reg_pass = input ("Password:")
    reg_age = input ("age:")
    reg_group = input ("Year Group")
    print ("Is this infomation correct?")
    print ("Name:",reg_name)
    print ("password:",reg_pass)
    print ("Age:",reg_age)
    print ("Year Group:", reg_group)
    reg_correct = input ("[Y/N]").lower()
    if reg_correct == "y":
        reg_user = reg_name[0:3]+reg_age
        reg_write = open("D:\\Computer science\\Computing test\\logindata.txt","a")
        reg_write.write (reg_user+","+reg_name+","+reg_pass+","+reg_age+","+reg_group+"/n")
        print ("Your username is:",reg_user)
        reg_write.close()
        break
    elif reg_correct == "n":
        print ("Please Re-enter your infomation")
    else:
        Print ("Invalid input! Please try again...!")

Answer 1

我认为您可能需要\n而不是/n。它是实际的换行符。否则，它将在文件中的每个语句之间添加“/ n”。 \n创建换行符。

print ("enter your name, age, and year group and password")
while True:
    reg_name = input("Name:"))
    reg_pass = input ("Password:")
    reg_age = input ("age:")
    reg_group = input ("Year Group")
    print ("Is this infomation correct?")
    print ("Name:",reg_name)
    print ("password:",reg_pass)
    print ("Age:",reg_age)
    print ("Year Group:", reg_group)
    reg_correct = input ("[Y/N]").lower()
    if reg_correct == "y":
        reg_user = reg_name[0:3]+reg_age
        reg_write = open("D:\\Computer science\\Computing test\\logindata.txt","a")
        reg_write.write (reg_user+","+reg_name+","+reg_pass+","+reg_age+","+reg_group+"\n")
        print ("Your username is:",reg_user)                                       #   ^^^
        reg_write.close()
        break
    elif reg_correct == "n":
        print ("Please Re-enter your infomation")
    else:
        Print ("Invalid input! Please try again...!")

不同的方式：

您还可以使用 writelines（）方法避免转义字符。

reg_write.writelines (reg_user+","+reg_name+","+reg_pass+","+reg_age+","+reg_group)

Answer 3

您可以使用"babel-plugin-react-html-attrs" "babel-plugin-transform-class-properties" "babel-plugin-transform-decorators-legacy" "babel-preset-es2015" "babel-preset-react"功能将信息写入文件。通过使用print模块，您可以轻松运行一些错误检查，以帮助验证您的文件是否可访问。使用Python最近添加的格式字符串，打印输出变量非常容易。

pathlib

Python写入新行
