Python problem

[Laurence26]

I found this little program for a game in a book.

class Tank (object):
	def _init_(self, name):
		self.name = name
		self.alive = True
		self.ammo = 5
		self.armor = 60

It is named tank.py
When I import it in python and I try to add

my_tank = Tank("Bob")

Python gives an error
NameError: name 'Tank' is not defined

Does anyone has an idea to solve this problem

There is no way to tell since the code you use to import is not included. Here is a link to the "Dive Into Python" chapter on import http://diveintopython.org/object_oriented_framework/importing_modules.html

Tank() is a class defined by your application. So you would have to have:

class Tank():

Somewhere, for your code to work.

You major problem is that __init__() uses double underlines prefix and postfix.

Also, remember that the module name and its file name are case sensitive!

Here is an example:

# save module as tank.py  (file name is case sensitive!)

class Tank (object):
    def __init__(self, name):
        self.name = name
        self.alive = True
        self.ammo = 5
        self.armor = 60

# test the module
if __name__ == '__main__':
    mytank = Tank("Bob")
    print mytank.name, mytank.armor  # Bob 60

Your program should import the modules like this:

# module was saved as tank.py (case sensitive)

import tank

mytank = tank.Tank("Bob")

print mytank.name  # Bob

Please make your thread title more specific, instead of "Python Problem" use "Problem with Python Class"

Well,
Thanks for the ideas but none if them have worked.
I now get an error
TypeError: default _new_ takes no parameters.
I have really no idea to solve this problem.

You did not fix the misnamed __init__() function in your class!
These are double underlines front and back!

Yea buddie maybe your error is the double underlines, they look like one big underline but are indeed two underlines together __ = _+_
