Question

如果我有这段代码来编写txt文件，我只是想知道为什么每次我在输入中键入\ n时都不会创建这样的换行符。

<a href="/buttons/" class="link external panel-close">Buttons</a>

这是代码

This is the example txt file\n it doesn't create a new line\n how can I make it do it?

Answer 1

您可以使用replace：

def create():
    path = input("What file would you like to create: ")
    output_file = open(path, 'x')
    text = input("What would you like to write? ")
    output_file.write(text.replace('\\n', '\n'))
    output_file.close()
def append():
    path = input("What file would you like to append: ")
    output_file = open(path, 'a')
    text = input("What would you like to write?")
    output_file.writelines(text.replace('\\n', '\n'))
    output_file.close()
write = input("Would you like to write something today, or edit? ")
if write == "Write":
    create()
if write == "Edit":
    append()

Answer 2

这是一个非常简单的答案。

input = input("Would you like to Write a new document, or Edit an existing one?  ")
if input == Write:
    file = open(path, "w")
    file.write(text)
    file.write("\r\n")
    file.close()
if input == Edit:
    file = open(path, "a")
    file.write(text)
    file.write("\r\n")
    file.close()

Answer 3

How do you input escape sequences in Python?中提到了\n与input不兼容的原因。 input函数无法识别任何转义序列，例如\n，因为它会按字面意义解释文本。

要将\n解释为来自text的换行符，请进行以下导入并调整write()和writelines()的参数，以允许用户输入{{1} }包括新行：
