converting backslash codes - Skaperen - Oct-14-2016 i know python has such a thing but cannot remember the terms or names for this. my guesses are not helping my search. foo('\\'+'n'+'\\'+'t') -> '\n\t' e.g having the backslash codes (any of them, not just these 2), convert them to the actual vales. this is conversion done to string literals somewhere in the python interpreter. but i have seen this before, so i know exists as a simple function call, but my searches are all failing. repr() does the reverse. RE: converting backslash codes - Mekire - Oct-14-2016 I'm not quite sure I understand what you want. Does this hit on it? >>> chr(10) '\n' >>> ord('\n') 10Edit: I think these links hit on your question actually: How do I un-escape a backslash-escaped string in python? how do I .decode('string-escape') in Python3? RE: converting backslash codes - Skaperen - Oct-14-2016 i was hoping it was usable in python 2. i guess i will have to get this old code cleaned up and use it.. RE: converting backslash codes - nilamo - Oct-18-2016 You mean marking the string as 'raw' by putting "r" in front of it? >>> x = '\\n' >>> y = r'\n' >>> x == y True RE: converting backslash codes - Skaperen - Apr-21-2018 warning: very old thread (Oct-18-2016, 03:08 PM)nilamo Wrote: You mean marking the string as 'raw' by putting "r" in front of it?>>> x = '\\n' >>> y = r'\n' >>> x == y True no. i mean converting the kinds of backslash codes you might see expressed in source code, from being in actual strings to the binary result. if i have code that reads input into a string and i type in a backslash and an 'r' i will have 2 characters, a backslash and an 'r'. source code to get exactly the same thing would be '\r'. but source code is merely explaining this; not how it is actually gotten. wherever those 2 characters come from, i want to apply the same effect as you see in source code: foo = '\r'in the above case the variable named foo will end up with just 1 character. what i want (and have coded) is a function to do that. my struggle has been explaining what i am doing. the "raw" concept is not what i am doing, although a reference to it might explain it to you. i'm thinking of it as an encoding. perhaps this code would explain better what i have and what i want that can do the conversion abc = chr(92) xyz = chr(114) woot = convert(abc+xyz) print(ord(woot))this would print out 13. what i want is that convert() function in a form that supports all such control codes. |
