I have string like follow
12560/ABC,12567/BC,123,567,890/JK

I want above string to group like as follow
(12560,ABC)
(12567,BC)
(123,567,890,JK)

i try regular expression i am able to get first two not the third one.
can regular expression given data in different groups

Without regular expressions:

def group(string):
result = list()
for item in string.split(','):
if '/' in item:
result.extend(item.split('/'))
yield tuple(result)
result = list()
else:
result.append(item)

def main():
string = '12560/ABC,12567/BC,123,567,890/JK'
print list(group(string))

Without regular expressions:

def group(string):
* * result = list()
* * for item in string.split(','):
* * * * if '/' in item:
* * * * * * result.extend(item.split('/'))
* * * * * * yield tuple(result)
* * * * * * result = list()
* * * * else:
* * * * * * result.append(item)

def main():
* * string = '12560/ABC,12567/BC,123,567,890/JK'
* * print list(group(string))

How about:

>>string = "12560/ABC,12567/BC,123,567,890/JK"
r = re.findall(r"(\d+(?:,\d+)*/\w+)", string)
r

['12560/ABC', '12567/BC', '123,567,890/JK']

>>[tuple(x.replace(",", "/").split("/")) for x in r]

[('12560', 'ABC'), ('12567', 'BC'), ('123', '567', '890', 'JK')]

Looks like each item is:
- a list of 1 or more integers, in a comma-delimited list
- a slash
- a word composed of alpha characters

And the whole thing is a list of items in a comma-delimited list

Now to implement that in pyparsing:

>>data = "12560/ABC,12567/BC,123,567,890/JK"
from pyparsing import Suppress, delimitedList, Word, alphas, nums, Group
SLASH = Suppress('/')
dataitem = delimitedList(Word(nums)) + SLASH + Word(alphas)
dataformat = delimitedList(Group(dataitem))
map(tuple, dataformat.parseString(data))

[('12560', 'ABC'), ('12567', 'BC'), ('123', '567', '890', 'JK')]
