c++ - Python RE - Regular expression for matching a printf-like format string with escaped quotation marks -


I am writing a small + preprocessor in Python, which should have format strings like printf. I need a regular expression, which corresponds to other quote marks in the first place, but ('' '' ') is ignoring all the escape marks. Here is an example: 

  foo bar, "value \" s \ ":% s", "foobar");

I need a regex for this: 

  "value \":

I have so far: 

  (". *?")

But I could not find any way to avoid quotation marks I'm so grateful if someone can give me a solution / tip.

Thank you in advance!

You can try regex below to match the first of all the characters Hala and the other ", 

  \". *] [^ \\] \ "

< Previous> & gt; & Gt; & Gt; S = r'foo (bar, "value \" s \ ":% s", "foobar"); '& Gt; & Gt; & Gt; M = re.search (r '". *? [^ \\]"', s)> gt; & Gt; & Gt; Results = m.group (0)> gt; & Gt; & Gt; Print result "value \" s \ ":% s"

Explanation:

  • "< / Code> matches the first double quote marks.
  • . *? Any characters match zero or more times. ? After * matches an unwillingness. << Li> matches << code> " (Double quote) symbol

Python Equivalent for matlab cart2pol and pol2cart -

I would like to use pol2cart and cart2pol for two functions in MATLAB. Is there an equivalent Python Function? Or if we can define work? For example, I tried to use the CeMatePactor function, but it only accepts one argument, I have 2 arguments to cross the polar and REC function. P> I have tried to use this function for cart2pol: def cart2pol (x, y): theta = atan2 (y, x) rho = Sqrt (x ** 2 + y ** 2) returns (theta, ro) thanks
