I'm trying to build a sage 9 code into a format of python module with .py file, and run the module in the sage command line. Most of the issue could be fixed through this webpage https://doc.sagemath.org/html/en/tutorial/programming.html by importing packages with command line such as
import_statements('is_integer')
i.e. set up the sage environment manually. However, a built in mechanism in sage was the usage of rings. i.e. 1/3 in sage automatically returned 1/3 in rational ring, but when put the code in python module and run it in sage command line.
sage: module_name.value1
was in class 'float' or 'int'
How to set up the environment so that the module could run operation in sage rings automatically?
