Does REGEX differ from PHP to Python -

I found this post:

I have started to change some of my old PHP code into Python (due to G's app engines, etc.), and now I would like to know whether regex is 100% convertible, simple copy & amp; Paste.

relationship,

Python uses syntax as a parallel syntax and PHP uses syntax, so it should be almost identical. Read about possible.

The only real difference is that the expression in PHP should be attached.
