What does a line of python code do?

Question

Django

There is a line of code:

perms = getattr(self, '_get_%s_permissions' % from_name)(user)

Can you tell me what "(user)" means at the end of the line?

Answer 1

getattr() will return the instance attribute, which appears to be a method with some suffix - _get_XXX_permissions , and then call it with the user parameter
