Is this a April 1 post for fools.
Multiplication with an asterisk symbol is built into python.
The same symbol used in other contexts has other contexts has an assortment
of largely unrelated meanings such as meaning everything when used to
import.

I guess the operator "*" can be imported from any module... :-)
No import is necessary.

A: No, this cannot work. To multiply, you need the multiplication
operator. You can import the multiplication operator from "mat

Or alternatively, that you used an interactive Python environment and

I think you may be doing something wrong.
If I run:
>>> l = [1, 2, 3, 4, 5]
>>> i = 0
>>> for a in l:
...i += 2 * a
...
>>> i
30
The result is 30 as expected.
Nowhere near the 155 that you are getting. :/
Again, could you state which version of python are you using (and what
OS) so
In my python 3.2, no problem:
>>> l=[1,2,3,4,5]
>>> i=0
>>> for a in l:
... p=2*a
... t=p+i
... i=t
... print("p={}, t={}, i={}".format(p,t,i))
...
p=2, t=2, i=2
p=4, t=6, i=6
p=6, t=12, i=12
p=8, t=20, i=20
p=10, t=30, i=30
>>> t
30
>>>

Python gives an answer as 45. But i am getting 30 when i execute
manually. Is there any different multiplication pattern in python?
Thank yu.
I think
I tried running your code in ipython:
In [1]: l = [1,2,3,4,5]
In [2]: i = 0
In [3]: for a in l:
...: p = 2 * a
...: t = p + i
...: i = t
...:
In [4]:
In [4]: t
Out[4]: 30
The output from Python was 30, not 45. What Python version are you
running?

Usually, it is safest (and typically true) to assume that Python
performs no optimizations. To go beyond making assumptions, it is easy
to run a few timings:

Do you know that these shortcuts are optimizations, or are you just
assuming it takes less time to do the comparison than it
