Consider the following:
class car:
pass
tesla=car()
When I do type(tesla), this gives __main__.car, as I expect.
But if I have:
class car:
pass
tesla=car
then type(car) gives type.
From another post here on SO, it really shouldn't matter how I instantiate the class. But clearly as we see here, the type of the object is different. I am an absolute beginner to python, could you please let me know what is going on here.
Thanks!
In the second case, you're not instantiating the class, just giving it another name, tesla. The parentheses are required for instantiation.

s = [1,2,3,4]
list(map(lambda parameter : parameter*2, s))
I am trying to run this simple line of code, but ending up getting
TypeError: 'list' object is not callable
can anybody please suggest me a solution for this
Your code works as is. I'm guessing (for lack of info) that somewhere above these lines of code you've overridden list as an actual list...
Check your code for this kind of error, and if it exists then refactor and rename so as to not use list as a parameter in your code.

Hey So i typed in this code:
opennote = open('C:\\Users\\My_username\\coolnotepad.txt')
(with my username ofc)
yet i keep getting this
TypeError: 'str' object is not callable
Helpp!
A callable has a __call__ method defined, meaning you can follow it with () to invoke its functionality.
open is a reserved keyword, which, if overridden by a variable, shows the behavior you are seeing.
Using a text editor that supports the python syntax with highlighting can help you avoid issues like this.

I am trying to write a problem with classes in python. I am a beginner. I cannot realized where the problem is. When I run the code I received this error:
File "D:/Facultate/Python/Bibliotek_Classe/Classe.py", line 43, in add_client
self.client_list.append(client)
AttributeError: 'CrudOperationOnClient' object has no attribute 'client_list'
And this is the class where it is supposed to be a mistake. Thank you very much!
this is the code
write def __init__(self): instead of __int__(self):

can't get a simple class example to work and i have no clue why.
why does my object have no attributes?
class Player(object):
def _init_(self, name="n", hp=25):
self.name = name
self.hp = hp
def take_hit(self):
self.hp -= 5
dude= Player()
print (dude.name)
dude.take_hit
print (dude.hp)
__init__, like all Python magic methods, needs to have two underscores on each side, not one.

I am trying to figure out why Python is throwing a "Can't assign to function call" error for my last line of code. It goes away when I take out everything after the first comma. Is there a better way syntactically to do this?
class UserProperty(models.Model):
state = models.ManyToManyField(), USState, blank=True, null=True
You should put parenthesis around all the parameters like this:
class UserProperty(models.Model):
state = models.ManyToManyField(USState, blank=True, null=True)
