[Tutor] Python Regex References

2013-01-08 Thread Devyn Collier Johnson 
I am trying to convert the SED code below to Python3.3. How do I
reference the value of the first and second wildcards so that I can put
the variable values in the "replace" portion of the code?

SED (this works):
export DATA=$(echo "$DATA" | sed -r -e "s|^ $|\1(>=>)\2|gI")

Python3.3 (attempted):
DATA = re.sub('^$', '\1(>=>)\2',
DATA, flags=re.I)


Thank you,
