Changing Class Members in Python
In the previous fact, we have seen that Python doesn’t have the static keyword. All variables that are assigned a value in the class declaration are class variables.
We should be careful when changing value of class variable. If we try to change a class variable using object, a new instance (or non-static) variable for that particular object is created and this variable shadows the class variables. Below is Python program to demonstrate the same.
Initially a.stream = cse b.stream = cse After changing a.stream a.stream = ece b.stream = cse
We should change class variables using class names only.
a.stream = cse Class variable changes to mec Value of variable steam for each object a.stream = mec b.stream = mec
