如何将新数据附加到新行 [英] How to append new data onto a new line
问题描述
我的代码如下:
def storescores():
hs = open("hst.txt","a")
hs.write(name)
hs.close()
所以如果我运行它并输入Ryan"然后再次运行并输入Bob"文件 hst.txt 看起来像
so if I run it and enter "Ryan" then run it again and enter "Bob" the file hst.txt looks like
RyanBob
代替
Ryan
Bob
我该如何解决这个问题?
How do I fix this?
推荐答案
如果你想要换行,你必须明确地写一个.通常的方式是这样的:
If you want a newline, you have to write one explicitly. The usual way is like this:
hs.write(name + "\n")
这使用反斜杠转义,\n
,Python 将其转换为字符串文字中的换行符.它只是将您的字符串 name
和该换行符连接成一个更大的字符串,然后写入文件.
This uses a backslash escape, \n
, which Python converts to a newline character in string literals. It just concatenates your string, name
, and that newline character into a bigger string, which gets written to the file.
也可以使用多行字符串文字代替,如下所示:
It's also possible to use a multi-line string literal instead, which looks like this:
"""
"""
或者,您可能想使用字符串格式而不是串联:
Or, you may want to use string formatting instead of concatenation:
hs.write("{}\n".format(name))
所有这些都在教程的输入和输出章节中进行了解释.
All of this is explained in the Input and Output chapter in the tutorial.
