[Tutor] Getting Started

I have programming experience using Fortran, Pascal, Modula 2, and some training in C++. My nephew told me about Python and it sounded intriguing. I downloaded Python 3.3.0 from this website (www.python.org) and installed it with no apparent difficulty. To learn the language I bought a book fr

[Tutor] arrangement of datafile

Hi, I am new in programming and want to try Python programming (which is simple and easy to learn) to solve one problem: in which I have various long file like this: 1 GLY HA2=3.7850 HA3=3.9130 2 SER H=8.8500 HA=4.3370 N=115.7570 3 LYS H=8.7530 HA=4.0340 HB2=1.8080 N=123.2380 4 LYS H=7.9100 HA=3.

I just wrote a unittest for this function here: def PositiveCalculator(*summands): if all(x > 0 for x in summands): return sum(summands) else: raise ValueError("negative value") Here's the test (I want to test whether the function works if the user enters floats instead of
