Python C program subprocess hangs at “for line in iter”
Ok so I’m trying to run a C program from a python script. Currently I’m using a test C program:
c#
Convert Python program to C/C++ code?
is it possible to convert a Python program to C/C++?
Regular expression to detect semi-colon terminated C++ for & while loops
In my Python application, I need to write a regular expression that matches a C++ for or while loop that has been terminated with a semi-colon (;). For example, it should match this:
Approximating data with a multi segment cubic bezier curve and a distance as well as a curvature contraint
I have some geo data (the image below shows the path of a river as red dots) which I want to approximate using a multi segment cubic bezier curve. Through other questions on stackoverflow here and here I found the algorithm by Philip J. Schneider from “Graphics Gems”. I successfully implemented it and can report that even with thousands of points it is very fast. Unfortunately that speed comes with some disadvantages, namely that the fitting is done quite sloppily. Consider the following graphic:
How to calculate the angle between a line and the horizontal axis?
In a programming language (Python, C#, etc) I need to determine how to calculate the angle between a line and the horizontal axis?
Calling a python method from C/C++, and extracting its return value
I’d like to call a custom function that is defined in a Python module from C. I have some preliminary code to do that, but it just prints the output to stdout.
Py_Initialize fails – unable to load the file system codec
I am attempting to put together a simple c++ test project that uses an embedded python 3.2 interpreter. The project builds fine but Py_Initialize raises a fatal error:
What is the internal precision of numpy.float128?
What precision does numpy.float128 map to internally? Is it __float128 or long double? Or something else entirely?
Is there go up line character? (Opposite of n)
I would like to overwrite something on a line above in a serial console. Is there a character that allows me to move up?
C and Python – different behaviour of the modulo (%) operation
I have found that the same mod operation produces different results depending on what language is being used.
