Python Programming for Biology: Bioinformatics and Beyond

The regular expression module ‘

re

’

The table below describes selected functions that are in the re module and bound methods

of the re.RegexpObject class, which we represent here as reObj. Note in many cases the

RegexpObject methods accept optional start and end points to specify which region of the

text  string  to  search  within.  Also,  all  of  the  re  methods  below  that  accept  a  pattern  can

include optional flags to specify special behaviour: e.g. re.compile(patt, flags=re.I) is used

for case-insensitive searching. These are listed at
