Hmm, apparently python doesn't care about whitespace in method calls or
attribute access:
class person:
def __init__(self):
self.name ="jim"
def hi(self):
print("hello")
>>> guy = person()
>>> guy. name
'jim'
>>> guy .hi()
hello
That at least explains that par

answer = 6 .__sub__(7 .__neg__())
answer
13
Why does this work? I don't even understand why python recognizes
that I'm
trying to access the numbers' __sub__
Why does this work
>>> a = 6
>>> b = 7
>>> answer = a.__sub__(b.__neg__())
>>> answer
13
but this does not?
>>> answer = 6.__sub__(7.__neg__())
SyntaxError: invalid syntax
I searched the internet, and found someone suggest adding spaces after each
number, which indeed works properly.
