I should point out that print doesn't magicly let you "+" a str and an int.
You would need to write:
print ('nope. the number i was thinking of was ', number)
You can see that that doesn't use "+". The print function calls str() on
each of its arguments, then writes the result to the output. str() on the
string returns itself, and str(number) returns the number in text form.
You can see then that you don't need str(number) yourself, and therefore do
not need to store it in a variable.
Also, while you can bind a value of any type to any variable, as you have
here by binding an int to "number" and then later a str to "number", it is
not a great idea. A particular variable should usually always hold the same
type of value; this storing of different types of values in the same
variable contributed to your problem.
Cheers,
Cameron Simpson (formerly c...@zip.com.au)
Thanks for everything,it's running
saw where storing two different types in the same variable!

Your issue is in this line, it should be `__init__` rather than
`_init_` (that is, two underscores before and after "init").
Hope this helps,

If you look closely at your tutorial you will find that init()
has two underscores before and after the name:
def __init__()
rather than
def _init_()
The reason for your error is that all classes inherit from object.
So when you call Human() the interpreter looks for an __init__()
method and, not finding one(because yours only has one undercore),
it looks at the one defined in object. But the object init()
takes no parameters and so there is a mismatch between your
call to Human() and the object.__init__() definition.
Hence the error message.
To fix it use two underscores.
All of the "magic" methods used by Python have these double
underscores and hence are often referred to as "dunder" methods.
You should avoid defining any new methods (ie new names) with
double underscores yourself, in case Python introduces a
similar method in a future version.

That looks suspiciously like my tutorial ;-)
The answer is to use two underscores around init():
def __init__(...)
not
def _init_(...)
This is explained in more detail in a box at the end
