我正在尝试使用以下代码动态构建一个字符串
output = "".join(["network", "\", "account"])
转义后的结果应该是network\account
如何在 Python3 中执行此操作而不会遇到此错误
File "<stdin>", line 1
"".join(["network", "\", "account"])
^
SyntaxError: invalid syntax
请您参考如下方法:
原始字符串是另一种方式(有人已经使用转义字符发布了答案)。
在引号前加上 r:
r'network\account
编辑:
我意识到这实际上不适用于您使用单个反斜杠的示例，
我已经发布了:
output = "".join(["network", r"\", "account"])
但是根据 Python 文档。
Even in a raw literal, quotes can be escaped with a backslash, but the backslash remains in the result; for example, r"\"" is a valid string literal consisting of two characters: a backslash and a double quote; r"\" is not a valid string literal (even a raw string cannot end in an odd number of backslashes). Specifically, a raw literal cannot end in a single backslash (since the backslash would escape the following quote character).
