Python 行继续字符后出现意外字符

Question

我对 Python 很陌生。我正在构建一个字符串，它只不过是网络位置的路径，如下所示。但它输出错误:“行继续字符后出现 Python 意外字符”。请帮忙。我看到了这篇文章，但我不确定它是否适用于我的场景:

syntaxerror: "unexpected character after line continuation character in python" math

s_path_publish_folder = r"\\" + s_host + "\" + s_publish_folder "\" + s_release_name

其中一个 \ 反斜杠转义其后面的 " 双引号。字符串的其余部分结束> 就在下一个 \ 反斜杠之前，第二个反斜杠被视为续行符。因为紧随其后还有另一个 " ，您会收到错误:

s_path_publish_folder = r"\\" + s_host + "\" + s_publish_folder "\" + s_release_name
#                                         ^^ not end of string   ||
#                                        ^--- actual string  ---^||
#                                              line continuation /|
#                                                 extra character /   

您需要将这些反斜杠加倍:

s_path_publish_folder = r"\\" + s_host + "\\" + s_publish_folder "\\" + s_release_name

更好的是，在这里使用os.path模块；例如，您可以使用os.path.join():

s_path_publish_folder = r"\\" + os.path.join(s_host, s_publish_folder, s_release_name)

或者您可以使用字符串模板:

s_path_publish_folder = r"\\{}\{}\{}".format(s_host, s_publish_folder, s_release_name)
