New submission from Eric Atienza <[EMAIL PROTECTED]>:
the following code :
def test():
code=''
def sub(n):
for i in range(n):
code+=str(i)
sub(5)
sub(10)
return code
>>> test()
Traceback (most recent call last):
File "<console>", line 1, in <module>
File "<console>", line 6, in test
File "<console>", line 5, in sub
UnboundLocalError: local variable 'code' referenced before assignment
error came from the += operator.
Tested for code initialized to '', to 0
I guess it's the same for all inline operators.
I agree that global variables CANNOT be assigned, it's ok.
But += (and I guess *= etc) operators are not assignements, and are not
different from .append(), or .extend() methods.
I was expecting += to work the same as append() method
