It just iterates over the PI string manually and compares
the birth date with the first 4 PI string characters.
It would probably be more pythonic and easier to read
to use startswith() instead

I think this is to eliminate the period after the 3 of PI

This is the core of it.
It starts with i = 0 and goes up to i = n-4
If b[i] to b[i+3] equals the birthdate you count
a match
You could rewrite it as
for i in range(n-3):
if b.startswith(get_year, i):
count += 1
