好的,基本上,我正在做一个程序,允许我列出即将到来的GCSE的复习主题。我的代码如下所示,但是txt文件没有被写入!! 如果有人有时间,如果您能告诉我如何: A) 使“需要另一个主题”问题无限大,直到用户说“n”(否) B) 覆盖同名的现有文件
代码:
print("Which subject are we doing today?")
subject = input("Subject: ")
file = open(subject + " Revision Topics.txt", "w")
file.write("Here are a list of " + subject + " topics that need revising:\n")
print("Got topics to revise?")
intro = input("y or n: ")
if intro == "y":
print("Which topic needs revising?")
topic1 = input()
print("Any more?")
anotherone = input("y or n: ")
if anotherone == "y":
print("Which topic also needs revising?")
topic2 = input()
print("Any more?")
anotherone = input("y or n: ")
if anotherone == "y":
print("Which topic also needs revising?")
topic3 = input()
print("Any more?")
anotherone = input("y or n: ")
if anotherone == "y":
print("Which topic also needs revising?")
topic4 = input()
print("Any more?")
anotherone = input("y or n: ")
if anotherone == "y":
print("Which topic also needs revising?")
topic5 = input()
print("Any more?")
anotherone = input("y or n: ")
if anotherone == "y":
print("Which topic also needs revising?")
topic6 = input()
print("Any more?")
anotherone = input("y or n: ")
if anotherone == "y":
print("Which topic also needs revising?")
topic7 = input()
print("Any more?")
anotherone = input("y or n: ")
if anotherone == "y":
print("Which topic also needs revising?")
topic8 = input()
print("Any more?")
anotherone = input("y or n: ")
if anotherone == "y":
print("Which topic also needs revising?")
topic9 = input()
print("You have reached the maximum number of topics.")
elif anotherone == "n":
topic9 = ("")
else:
print("Answer not recognised! :(")
elif anotherone == "n":
topic8 = ("")
else:
print("Answer not recognised! :(")
elif anotherone == "n":
topic7 = ("")
else:
print("Answer not recognised! :(")
elif anotherone == "n":
topic6 = ("")
else:
print("Answer not recognised! :(")
elif anotherone == "n":
topic5 = ("")
else:
print("Answer not recognised! :(")
elif anotherone == "n":
topic4 = ("")
else:
print("Answer not recognised! :(")
elif anotherone == "n":
topic3 = ("")
else:
print("Answer not recognised! :(")
elif anotherone == "n":
topic2 = ("")
else:
print("Answer not recognised! :(")
elif anotherone == "n":
topic1 = ("")
file.write(topic1 + "\n" + topic2 + "\n" + topic3 + "\n" + topic4 + "\n" + topic5 + "\n" +topic6 + "\n" +topic7 + "\n" + topic8 + "\n" +topic9 + "\n")
你知道吗文件.close() 打印(“好!所以,“+主题+”修订主题.txt已保存到“文档”下的GCSE修订文件夹中。\n\n“好!”)你知道吗
结束代码
非常感谢您的帮助,非常感谢<;3
更新:我们已经修复了不保存的问题,但是现在IDLE上的错误告诉我topic9没有定义?但是,我在elif中为topic9设置了一个备份,将其定义为“”
有什么想法吗?你知道吗
为了始终确保文件正确关闭,通常最好使用
with open(something) as name
:上面的代码将处理文件的打开、写入和关闭—使用此方法,您不必记住关闭文件。你知道吗
使用循环的魔力来解决你的第一个问题。你知道吗
至于你的第二个问题,哪一部分没有写?文件是否正在创建?如果你用管理员权限运行呢?你知道吗
