Within the Python function count_elements(), one micro-optimization you could make is to declare get = hist.get before the for loop. This would bind a method to a variable for faster calls within the loop.It can be helpful to build simplified functions from scratch as a first step to ...
The programmer does not have to explicitly declare the type of variable; rather, the Python interpreter decides the type of the variable and how much space in the memory to reserve. Considering the following example, we declare a string, an integer, a list, and a Boolean, and the ...

Python is dynamic, so one does not require to declare variables, and they exist automatically in the first scope where they are assigned. Only a regular assignment statement is required. TheNoneis a special object of typeNoneType. It refers to a NULL value or some value that is not availabl...
