This might help you You misunderstand the scope of import . Firstly, It's PEP practice to put module on the top, secondly and most importantly, it's not about best practice,it works that way. Every time You import any class or function from your file (or module) import **run ahead always.

Python architecture - import extra modules, or import modules in code execution section?

will be helpful for those in need As per PEP 8, all imports should be together at the top of the file. Having them spread throughout the file leads to hard to maintain and debug software.
The only performance overhead I can think of is at program startup - it has to load more modules. Once the program is running there shouldn't be any extra overhead.

Best way to import modules inside a class?

This might help you So the problem here is one of scope. When you import inside a function (which occasionaly, see below) then the scope of that import is limited to inside that function:
def foo():
    import a

def bar():
    a.something() # won't work
import a

def foo():

def bar():

Writing unit tests: can I import all modules I need just once at class level, or do I have to import them again in each

I think the issue was by ths following , Given that the duplicated code you want to get rid of consists of imports, I completely agree with BrenBarn's response, because you don't need to import a module multiple times. For the general case where you want to run the same code before or after every test in a class you should use the setUp() and tearDown() methods of class unittest.TestCase.

What is the right way to import modules inside my class

With these it helps Anything declared inside a class definition becomes a class variable, a module included, so by importing math within a class definition, it becomes a class variable that is accessible only via the class object or the instance object, so:
class myClass:
    import math

    def __init__(self, value):
        self.value = value

    def sqrt(self):
        return math.sqrt(self.value)

NameError: name 'math' is not defined
def sqrt(self):
    return self.math.sqrt(self.value)
