yes, and it can differentiate its behavior between the regular launch and import

it depends on the Python version

yes, but it cannot differentiate its behavior between the regular launch and import

no. it is not possible; a module can be imported, not run

rearrange the source code to make it clearer

check the source code in order to see if its correct

execute the source code

translate the source code into machine code

yes, by using the hasattr attribute

yes. by using the hasattr () method

yes, by using the hasattr () function

no, it is not possible
