regex - How do I find a pattern like 252.63.71.62 in a text in Python with re(gex)? -


i have webpage, text using resources module in python. but, i'm not getting it, how pattern of numbers 126.23.73.34 document , extract out using re module?

you can use regex ips d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}

text = "126.23.73.34"; match = re.search(r'\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}', text) if match:    print "match.group(1) : ", match.group(0)

if looking complete regex ipv4 addresses can find appropriate regex here.

to restrict 4 numbers in ip address 0-255, can use 1 taken source above:

(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
