Python lists are the most generic implementation of array data structure in python. We can store objects with different data types in a single list. To create a list with given elements, we can use the list() c

Python’scollectionsmodule provides a convenient data structure calledCounterfor counting hashable objects in a sequence efficiently. When initializing aCounterobject, you can pass an iterable (such as a list, tuple, or string) or a dictionary as an argument. If an iterable is provided,Counterwill...
At first glance, this looks just like the standard list in Python. After all, both represent the list abstract data type covered earlier. What makes the array data structure special is a few unique features. In particular, an array must be: Homogeneous: All elements in an array share a co...

to create/contains the fixed size arrays, the"array"in C++ STL is"class"actually and they are more efficient, lightweight and very easy to use, understand,"array"class contains many inbuilt functions, thus the implementation of the operations are fast by using this rather that C-Style arrays...
More importantly, efficient exchange of array data between different hardware blocks might force the implementation to allocate the memory in multiple memory pools (e.g. dGPU and system DRAM). In some scenarios (to optimize performance and memory use) it might be beneficial to constrain the ...
