How to split items in Python list?

How can I turn the following list:

[['110T148A112', '24,0001100409'], 
 ['110T148A077','24,0001100316']]

into

[['110T148A112', '24,000', '1100409'], 
 ['110T148A077','24,000', '1100316']]

What is the syntactically cleanest way to accomplish this?

Thanks for any help!!

You can use re.findall to handle greater variability in the positioning and number of commas present in the strings:

import re
d = [['110T148A112', '24,0001100409'], ['110T148A077', '24,0001100316']]
r = [[a, *re.findall('(?<=,\d{3})\d+$|^\d+(?:,\d{3})+', b)] for a, b in d]

Output:

[['110T148A112', '24,000', '1100409'], ['110T148A077', '24,000', '1100316']]

If all the data is in the same format, you could just use a list comprehension with string slices:

lst = [['110T148A112', '24,0001100409'], 
 ['110T148A077','24,0001100316']]


res = [[l[0], l[1][:6], l[1][6:]] for l in lst]

Output:

[
 ['110T148A112', '24,000', '1100409'],
 ['110T148A077', '24,000', '1100316']
]
