Understanding multiple inheritance and method resolution order in Python 



# cat multiple_inheritance.py 
import inspect

class A(object): pass

class B(A): pass

class C(A): pass

class D(B): pass

class E(C): pass

class F(D, E): pass

print inspect.getmro(A)
print inspect.getmro(B)
print inspect.getmro(C)
print inspect.getmro(D)
print inspect.getmro(E)
print inspect.getmro(F)

Splitting python path using os.path module

Avoid using "/" at the end of the directory paths as they would generate empty filename when used with functions like os.path.split() > > > import os > > > os . path . split ( '/tmp/foo' ) ( '/tmp' , 'foo' ) > > > os . path . split ( '/tmp/foo/' ) ( '/tmp/foo' , '' ) Reference: https://docs.python.org/2/library/os.path.html
