What is the pythonic way to test whether two objects are the same, not just equal Question: My solution has been to make the object’s address into a string, which should always be unique. Below is a case where it works both ways, comparing the objects and comparing the values of str(object_a) and str(object_b). >>> …
Passing 3-dimensional numpy array to C Question: I’m writing a C extension to my Python program for speed purposes, and running into some very strange behaviour trying to pass in a 3-dimensional numpy array. It works with a 2-dimensional array, but I’m sure I’m screwing something up with the pointers trying to get it to …
Are Python variables pointers? Or else, what are they? Question: Variables in Python are just pointers, as far as I know. Based on this rule, I can assume that the result for this code snippet: i = 5 j = i j = 3 print(i) would be 3. But I got an unexpected result for …
Executing assembler code with python Question: I want to execute assembly code inside a python script. Is that possible? In C programming would be like this static inline getesp(){ __asm__(“mov %esp, %eax”); } But how to do that with Python? Is it possible? Asked By: Yuda Prawira || Source Answers: Python does not support this …
Pointers in Python? Question: I know Python doesn’t have pointers, but is there a way to have this yield 2 instead >>> a = 1 >>> b = a # modify this line somehow so that b “points to” a >>> a = 2 >>> b 1 ? Here’s an example: I want form.data[‘field’] and …
Pointers and arrays in Python ctypes Question: I have a DLL containing a C function with a prototype like this: int c_read_block(uint32 addr, uint32 *buf, uint32 num); I want to call it from Python using ctypes. The function expects a pointer to a chunk of memory, into which it will write the results. I don’t …
Simulating Pointers in Python Question: I’m trying to cross compile an in house language(ihl) to Python. One of the ihl features is pointers and references that behave like you would expect from C or C++. For instance you can do this: a = [1,2]; // a has an array b = &a; // b points …
