If I start using Python, I should be aware of the price I am paying. Speed is not a big problem for me, so an interpreted language is fine. Is packaging/installing very messy? Do I create dozens of files for a simple program calculating the sum of two numbers and product of two numbers in text boxes with one command to be clicked? Can I learn this much in the first couple of hours?

This form of packing is not desirable. I can't ask other people to install Python on their machines, and I also would not want show most of the code doing the calculations.

Another question I have is regarding reading numerical data from text files. Is it necessary to read one character at a time, or can one read like in Fortran and Basic (something like Input #5, X1, X2, X3)?
