hi
how can i use regexp to group these digits into groups of 3?
eg
line 123456789123456789
i have :
pat = re.compile("line\s+(\d{3})" , re.M|re.DOTALL)
but this only gives the first 3. I also tried
"line\s+(\d{3})+"
but also not working.
I need output to be ['123' ,'456','789', '123','456','789', .....]
thanks. 4 1196
You don't even need regex.
def
split_seq(seq,size):
# this is sort of the inverse of
flatten
# Source: http://aspn.activestate.com/ASPN/Coo.../Recipe/425044
return [seq[i:i+size] for i in range(0, len(seq),
size)]
line =
'123456789123456789'
print
split_seq(line,3)
Will that work for you? s9************@yahoo.com wrote:

hi
thanks.
I know it can be done without regexp, but its just for learning
purpose, i want to use regexp
eg
someword 123456789123456789 #this is a line of a file. 'someword' is a
word before the digits
I need to get the digits into groups of 3 based on whether i found
'someword'.
so i use this pattern :
"someword\s+(\d{3})"
but this will on give me the first 3. I need to group them all.
hope i explain it clearly.

Try:
import re
target_string = """not 123456789 but
try this line 987654321"""
try:
digits = re.compile(r'line\s+(\d
+)').search(target_string).group(1)
except AttributeError:
digits = ''
three_at_a_time = re.compile(r'\d{3}').findall(digits)
print three_at_a_time
