How to pass an input argument when creating an instance of a class?

Question

My idea was to implement the following class:

class name(object, name):
    def __init__(self, name):
        print name

Then the idea was to create two instances of that class:

person1 = name("jean")
person2 = name("dean")

I know that is not possible, but how can I pass an input argument into an instance of a class?

Answer 1

>>> class name(object):
...     def __init__(self, name):
...         self.name = name
... 
>>> person1 = name("jean")
>>> person2 = name("dean")
>>> person1.name
'jean'
>>> person2.name
'dean'

The problem in your initial definition of the class is that you've written:

class name(object, name):

This means that the class inherits the base class called "object", and the base class called "name". However, there is no base class called "name", so it fails. Instead, all you need to do is have the variable in the special __init__ method, which will mean that the class takes it as a variable.

class name(object):
  def __init__(self, name):
    print(name)

If you wanted to use the variable in other methods that you define within the class, you can assign name to self.name, and use that in any other method in the class without needing to pass it to the method.

For example:

class name(object):
  def __init__(self, name):
    self.name = name
  def PrintName(self):
    print(self.name)

a = name('bob')
a.PrintName()
bob

You just need to do it in correct syntax. Let me give you a minimal example I just did with Python interactive shell:

>>> class MyNameClass():
...   def __init__(self, myname):
...       print myname
... 
>>> p1 = MyNameClass('John')
John

Answer 4

Remove the name param from the class declaration. The __init__ method is used to pass arguments to a class at creation.

class Person(object):
  def __init__(self, name):
    self.name = name

me = Person("TheLazyScripter")
print me.name

Python Classes

class name:
    def __init__(self, name):
        self.name = name
        print("name: "+name)

Somewhere else:

john = name("john")

Output:
name: john

Actually you can! How about this?

class name(str):
    def __init__(self, name):
        print (name)
# ------
person1 = name("jean")
person2 = name("dean")
print('===')
print(person1)
print(person2)

Output:

jean
dean
===
jean
dean

class Person:

def init(self,name,age,weight,sex,mob_no,place):

self.name = str(name)
self.age = int(age)
self.weight = int(weight)
self.sex = str(sex)
self.mob_no = int(mob_no)
self.place = str(place)

Creating an instance to class Person

p1 = Person(Muthuswamy,50,70,Male,94*****23,India)

print(p1.name)

print(p1.place)

Output

Muthuswamy

India

Usm

Answer 8

It is a good idea to use different names for things that play different roles in the code. E.g. as in the following code:

class Onoma:
def __init__(self, dummy_name):
    self.name = dummy_name
    print(self.name)

Then

a = Onoma("MN")
a.name

returns

'MN'
