The 3.0 version of Python is often called Python 3000, or Py3k for short. This is a major upgrade compared to earlier versions of Python. In order not to bring too much burden, Python 3.0 was not designed with backward compatibility in mind.
Python3 Number (Number) syntax
Python numeric data types are used to store numerical values.
The data type is not allowed to be changed, which means that if the value of the numeric data type is changed, the memory space will be reallocated.
