Hello
I noticed a quirk difference between classes and functions
>>> x=0
>>>
>>> class Test:
x = x+1
print(x)
x = x+1
print(x)
1
2
>>> print(x)
0
Previous code doesn't generate any errors.
x at the right of = in first "x = x+1" line is
the global one (x=0), then x becomes local
within a function, this is not allowed
>>> x = 0
>>>
>>> def f():
x = x+1
>>> f()
UnboundLocalError: local variable 'x' referenced before assignment
Since x is written inside the function, it is considered as a local
variable and x in x+1 is undefined so this throw an exception
Any comment ?
