test() will fail at runtime with a NameError. You imported only
'myvar' from 'a', not 'a' itself (i.e. there is no variable 'a'
defined with 'b', only the variable 'myvar').
Assuming you changed the import to `import a`, then yes, a.myvar (both
within 'a' itself and when accessed from 'b') would have its value
changed by test().
