In Python we don't have to declare it a vegetable in a program.
If you need a vegetable in a program you can directly assign a value to the variable like this and then
start using the variable for it for the operations.
Say for example it is equal to ablest and as we know in Python where build act like pointers rather
than contain knows after certain operations are performed on a variable.

after this operation bind to the memory location containing this value will not only the value of a
variable can change during the program execution but the data type as well.
So for example you can assign an integer value to a variable like this use it as an integer for a while
like this and then assign a string to the variable say after you have performed operations on this variable
you can change the type of this variable by simply assigning the value.
In this case a string to the variable so the variable a now points to the string containing hello world.
And this does not throw an error in Python so changing the data type of a variable is allowed in Python
and it does not throw any error.
