A lot of confusion is caused by the print function converting an integer or
float
to a string before printing to console. thus both '1234 and '1234' are
shown as
1234 on the console. Similarly '15.4' and 15.4 are displayed as 15.4. There
is no way
to tell which is a string, which is an int and

Here you assign a floating point number to mmy_number but
the code Sama wrote was for working with strings read
from a text file.

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

On the contrary, the loop does an awful lot, just
not what the OP was expecting.

Can you explain what you think this loop line is doing?
I'm pretty sure it's not doing what you expect.

I wrote a program which checks if PI (first one million digits)
contains a person's birth year.
