Python 如何运行连续循环并向文本添加输入

我必须运行一个连续循环，直到用户做出相反的决定，这将把输入添加到文本文件中，但我似乎无法让while循环正常工作

这就是我到目前为止所做的：

def main():

    #Open a file named names.txt.
    outfile = open('names.txt', 'w')

    #user enters input
    fname = input("Enter first name:\t")
    lname = input("Enter second name:\t")
    telephone = input("Enter telephone number:\t")
    print("")
    continues = input("Continue? (y = yes):\t")
    input_list = [fname, lname, telephone, continues]

    outfile.write(fname)
    outfile.write(lname)
    outfile.write(telephone)

    outfile.close()

    while continues == 0:
        if continues == "y":
            fname = input("Enter first name:\t")
            lname = input("Enter second name:\t")
            telephone = input("Enter telephone number:\t")
            print("")
            continues = input("Continue?:\t")

            outfile.write(fname)
            outfile.write(lname)
            outfile.write(telephone)

            outfile.close()
        else:
            print("File Written")

#call main
main()

有人能帮我一下吗，我正在使用python 3.3.2，这里有一个循环正在工作。你能试一下并根据你的情况调整一下吗

run = None    
while run != 'n':
   run = raw_input('continue? [y/n]').lower()

您最好将整个过程包装在循环中：

Ex:

def main():

    while True: 

        fname = input("Enter first name:\t")
        lname = input("Enter second name:\t")
        telephone = input("Enter telephone number:\t")
        print ("")
        continues = input("Continue? (y = yes):\t").lower() # y to break the loop
        input_list = [fname, lname, telephone, continues]

        if continues == 'y':
            with open('names.txt', 'w') as outfile:
                # write things to outfile. 
                # The with block auto closes 
                # the file after it's statements
            print ('File Written')
            break # this is how you exit the loop

编辑：

def main():

    while True: 

        fname = input("Enter first name:\t")
        lname = input("Enter second name:\t")
        telephone = input("Enter telephone number:\t")
        print ("")
        continues = input("Continue? (y = yes):\t").lower() # y to break the loop
        input_list = [fname, lname, telephone, continues]

        if continues == 'y':
            with open('names.txt', 'w') as outfile:
                # write things to outfile. 
                # The with block auto closes 
                # the file after it's statements
            print ('File Written')
            break # this is how you exit the loop

也许这句话更有意义：

continues = input("Write to File? (y = yes):\t").lower()

---

据我所知，请尝试：

continues='y'
while 1:
    if continues == "y":
        fname = input("Enter first name:\t")
        lname = input("Enter second name:\t")
        telephone = input("Enter telephone number:\t")
        print("")
        continues = input("Continue?:\t")

        outfile.write(fname)
        outfile.write(lname)
        outfile.write(telephone)

        outfile.close()
    else:
        print("File Written")
        break

如果只给出代码的相关部分，您可能会得到更好的答案。

while continues==0:

-什么时候

continues

会是0？这个循环应该在什么条件下进行？我不知道我只是做了一个例子，而continues==y，它一直说y没有定义…

y

和

“y”

是不一样的。第一个是名为

y

（未定义）的变量，第二个是包含字符

y

的字符串。非常感谢，唯一的问题是“y”应该使循环继续，而不是破坏它，但谢谢：）很高兴我能帮上忙。正如您可能看到的，根据您的目的定制这一部分很容易。
