Is there a way to pass this value in as a raw string or something similar and have it stored as you would in most use cases? Hence the two strings in the text are printed out on separate lines, as displayed in the output. Using slices, you can get the string equivalent to the raw string. Ways to convert regular string to raw string Using r before string declaration Using double backslashes instead of a single backslash Using repr () function Get Python Python Converting cookie string into Python dict Converting cookie string into Python dict Answer a question In Fiddler, I captured an HTTPS request with the following cookie string sent from the client (visible in Inspectors > Raw): Cookie: devicePixelRatio=1; ident=exists; __utma=13103r69 Raw string literals in Python define normal strings that are prefixed with either an r or R before the opening quote. WebWhat is the Difference Between Raw String and Normal String in Python ? But when using a regular expression, we usually need to first define a matched pattern where the Raw string would be recommended. To convert a string to Unicode type, put a u before the text like this - u'string' or call the unicode() function like this - unicode('string').

So characters Hi are actually stored as 01001000 01101001 on the computer, which consumes 2 bytes (16-bits). Later, we find the difference between the lengths of the updated string and the original string to calculate the count of escape sequences in the string. d = c.encode().decode('unicode-escape'), https://code.sololearn.com/cOzEyLaN6gok/?ref=app, https://stackoverflow.com/questions/2428117/casting-raw-strings-python, https://stackoverflow.com/questions/24242433/how-to-convert-a-raw-string-into-a-normal-string.
