Supply condition in function call

Hi, I'm looking for a way to supply a condition to an if-statement inside a function body when calling the function. I can sort of get what I want with using eval (see code below) but I would like to achieve this in a safer way. If there is a solution which is safer while being less flexible, that

numpy/scipy: calculate definite integral of sampled data

Hi everyone, to calculate the definite integral of a function or an array of sampled data scipy provides (among others) the quad and trapz functions. So it is possible to compute e. g. the definite integral of cos(t) over some range by doing definite_integral= scipy.integrate.quad(cos,lower_limit

python as pen and paper substitute

Hello everyone, I am looking for ways to use a python file as a substitute for simple pen and paper calculations. At the moment I mainly use a combination of triple-quoted strings, exec and print (Yes, I know it's not exactly elegant). To clarify, I just start an editor, write a file that might lo

Tracing variable scope (local vs. global)

tion. Since I consider this behaviour a possible source of bugs due to personal sloppiness (e. g. forgetting to put "a=4" inside the function-body): Is there any way to automatically check that all variables in a function are either local or passed in as arguments? Regards, Manuel Graune

Usage of main()

Hello everyone, the standard structure of a python-program which is taught in all of the books I on python I read by now is simply something like: #!/usr/bin/python print "Hello, world!" ^D While reading about structuring a larger code-base, unit-testing, etc I stumbled on the idiom #!/usr/bin
