Yeah, where have you been? I don day use tensorflow

#EXAMPLE OF MISTAKE YOU MUST AVOID AS A BEGINNER USING PYTHON

print('example 1',1 is (not None)) # return False
print('example 2',1 is not None) # return True

'''
Before i explain why both statement return different value,Remenber that
'is' keyword in python is used to check if two objects have
the same id() and Note that, it is different from ==
which check if two objects have the same value

now let break down example 1;
1 is (not None)
(not None) in python will return True and
1 is True will return false because
1 and True represent different objects store with different id()
'''
print(not None) #return True

'''
Now example 2, 1 is not None
this check if id(1) is not id(None) and the answer
is True
'''
print(id(1),id(None))

What modules do I need to import to solve this.?
I used queue and random modules, but seems something is missing.
Bro, do share the solution with us. Seems none of us has a a good solution.

class share:
    def __init__(self,unit,price):
        self.unit=unit
        self.price=price

class stock:
    def __init__(self):
        self.shares=[]
        self.CGL=0
        self.total_units=0
        
    def buy(self,unit,price):
        self.total_units += unit
        self.shares.insert(0,share(unit,price))
        
    def sell(self,unit,price):
        assert unit < self.total_units, "units can't exceed total units"
        while unit > 0:
             share=self.shares.pop()
             curr_share=0
             if unit > share.unit:
                 curr_share=share.unit
                 unit -= share.unit
             else:
                 curr_share=unit
                 share.unit -= curr_share
                 self.shares.append(share)
                 unit = 0
             self.CGL += (curr_share * (price - share.price))
             self.total_units -= curr_share
                 
                 
        
S1=stock()
buy=[(100,20),(20,24),(200,36)]
for unit,price in buy:
    S1.buy(unit,price)
S1.sell(150,30)
print('capital gain is',S1.CGL,'\ntotal unit left',S1.total_units)

l=[2]
l.append(l.append(1))
print(l) 
#TRY GUESSING.....
#output: [2,1,None]

'''
WHY None?
reason behind this output is that
append() is a method that only add value at the
end of the list,so it does not have return value.
By default,None is returned if you dont specify
return value in a function

e.g
'''
def fun():
   v=5

print(fun())  #output: None

'''
so we can break it like this
'''
l=[2]
v=l.append(1) # v = None
l.append(v)
print(l) #output: [2,1,None]

see my boss oo!
I was carefully reading until I saw this your mention now....

My moniker made me not to reply mentions, they're too much!!!
Thanks a lot bro.. .
