[英]Split string by escape character
I'm trying to split a string by the escape character in Python. 我正在尝试用Python中的转义字符分割字符串。
This is the way I've been trying to do it: 这就是我一直在尝试的方法:
s = "C:\Users\as\Desktop\Data\pdf\txt\RTX_IDS_1DYS_20170610_0000_220279611-650000624200.txt"
s.encode("string_escape").split("\\")
When I run it, I get the following error: 运行它时,出现以下错误:
s = "C:\Users\as\Desktop\Data\pdf\txt\RTX_IDS_1DYS_20170610_0000_220279611-650000624200.txt"
^
SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape
prefix your string with r
- that will turn it into a raw string, telling python that \\
is a literal \\
. 给您的字符串加上
r
前缀-它将变成原始字符串,告诉python \\
是文字\\
。
s = r"C:\Users\as\Desktop\Data\pdf\txt\RTX_IDS_1DYS_20170610_0000_220279611-650000624200.txt"
parts = s.split("\\")
print(parts)
Output: 输出:
['C:', 'Users', 'as', 'Desktop', 'Data', 'pdf', 'txt', 'RTX_IDS_1DYS_20170610_0000_220279611-650000624200.txt']
