I have multiple stock names as follows

'ADANIENT29APR211120'
'AARTIIND29APR211360'
'ADANIPORTS29APR21730'

What I intend to do is to seperate the stock name, date, the price and print it as shown

'ADANIENT 29APR21 1120'
'AARTIIND 29APR21 1360'
'ADANIPORTS 29APR21 730'

Now i know about module known as datefinder which can help me to extract dates in python

I used it as follows:

import datefinder

string_with_dates = '''
    ADANIENT29APR211120PE
'''

matches = datefinder.find_dates(string_with_dates)
for match in matches:
    print(match)

The output this gives me is

runfile('C:/Users/hozef/AppData/Local/Temp/untitled0.py', wdir='C:/Users/hozef/AppData/Local/Temp')
2021-04-29 21:11:20

My question is that using datefinder I extracted the date in the string now how do i extract the name and price of the particular stock from the input string

Using re.findall:

inp = ['ADANIENT29APR211120', 'AARTIIND29APR211360', 'ADANIPORTS29APR21730']
for x in inp:
    parts = re.findall(r'^([A-Z]+)(\d{2}[A-Z]{3}\d{2})(\d+)$', x)[0]
    print(' '.join(parts))

This prints:

ADANIENT 29APR21 1120
AARTIIND 29APR21 1360
ADANIPORTS 29APR21 730

The regex used here says to match:

^
([A-Z]+)              stock name in all caps
(\d{2}[A-Z]{3}\d{2})  2 digit day, 3 letter all caps month, 2 digit year
(\d+)                 integer price
