Hi, need help with class, object

[Houston222]

class MyRouter(object):
 "This is a class that defines the aspects of a router"
 def _init_(self, routername, model, serialno, ios):
    self.routername = routername
    self.model = model
    self.serialno = serialno
    self.ios = ios

 def print_router(self, manuf_date):
    print("The router name is: ", self.routername)
    print("The router model is: ", self.model)
    print("The serial number of: ", self.serialno)
    print("The IOS version is: ", self.ios)
    print("The model and date combined: ", self.model + manuf_date)

 router1 = MyRouter("h1", "starhub", "123", "155")
 print(router1)

Hi , when i am trying to print out router 1 , it returns an error message below :

Error:
Traceback (most recent call last):
  File "C:/Users/teoho/PycharmProjects/untitled4/try1.py", line 1, in <module>
    class MyRouter(object):
  File "C:/Users/teoho/PycharmProjects/untitled4/try1.py", line 16, in MyRouter
    router1 = MyRouter("h1", "starhub", "123", "155")
NameError: name 'MyRouter' is not defined

Why is that so ? Many thanks in advance.

the indentation is not correct:

class MyRouter(object):
    "This is a class that defines the aspects of a router"
    def __init__(self, routername, model, serialno, ios):
        self.routername = routername
        self.model = model
        self.serialno = serialno
        self.ios = ios
    
    def print_router(self, manuf_date):
        print("The router name is: ", self.routername)
        print("The router model is: ", self.model)
        print("The serial number of: ", self.serialno)
        print("The IOS version is: ", self.ios)
        print("The model and date combined: ", self.model + manuf_date)
 
router1 = MyRouter("h1", "starhub", "123", "155")
print(router1)

Also, it's __init__, not _init_
finally, probably you want to implement __str__ method (e.g. instead of print_router

Note, strongly advise you to use 4 spaces per level of indentation, not 1.
