Is there a way that I can find out how many matches of a regex are in a string in Python? For example, if I have the string "It actually happened when it acted out of turn."

I want to know how many times "t a" appears in the string. In that string, "t a" appears twice. I want my function to tell me it appeared twice. Is this possible?

this works fine

ptr_str = lambda pattern,string1 :print(f'pattern = {pattern} times = {len(re.findall(pattern,string1))}')
pattern = 'AGATC'
str='AAGGTAAGTTTAGAATATAAAAGGTGAGTTAAATAGATCATAGGTTATATTGT'
ptr_str(pattern,string1)
