如何在Python中建立一個空類別？

class Amit: pass

class Amit: pass # Creating objects ob1 = Amit() ob2 = Amit() # Displaying print(ob1) print(ob2)

<__main__.Amit object at 0x7f06660cba90> <__main__.Amit object at 0x7f06660cb550>

class Student: pass # Creating objects st1 = Student() st1.name = 'Henry' st1.age = 17 st1.marks = 90 st2 = Student() st2.name = 'Clark' st2.age = 16 st2.marks = 77 st2.phone = '120-6756-79' print('Student 1 = ', st1.name, st1.age, st1.marks) print('Student 2 = ', st2.name, st2.age, st2.marks, st2.phone)

Student 1 = Henry 17 90 Student 2 = Clark 16 77 120-6756-79

# Empty function in Python def demo(): pass

a = True if (a == True) : pass else : print("False")

cond = True while(cond == True): pass
