1. The sys.getsizeof() Function. To retrieve the size of a Python object, the `sys` module’s `getsizeof()` function proves to be a valuable asset. It should be noted that the size returned may not always reflect the complete memory footprint due to the complex nature of Python’s...
( const char * str ) = 0; // size_t fread ( void * ptr, size_t size, size_t count, FILE * stream ); // Read block of data from stream /* Reads an array of count elements, each one with a size of size bytes, from the stream and stores them in the block of memory ...
The memory size of the dictionary object in bytes can be determined by the getsizeof() function. This function is available from the sys module. Like len(), it can be used to find the size of any Python object. This is particularly useful when we need code that needs to be performant...
