#66790 — TypeError: can't multiply sequence by non-int of type 'tuple'

HI,

I have a tuple. I need to make sqaure of elements of tuple and after that i want add all suared tuple elements for total. When i trying to do it, below error came.


Code:
seriesxlist1 = ((0.0,), (0.01,), (0.02,), (0.03,), (0.04,), (0.05,), (0.06,), (0.07,), (0.08,), (0.09,), (0.1,), (0.11,))

x2 = [x * x for x in seriesxlist1];

Error:
Traceback (most recent call last):
  File "<pyshell#188>", line 1, in <module>
    x2 = [x * x for x in seriesxlist1];
TypeError: can't multiply sequence by non-int of type 'tuple'



Please suggest me solution.

>>> x2 = [x * x for (x,) in seriesxlist1]
>>> x2
[0.0, 0.0001, 0.0004, 0.0009, 0.0016, 0.0025000000000000005, 0.0036, 0.004900000000000001, 0.0064, 0.0081, 0.010000000000000002, 0.0121]

1 Why you are making singleton tuples dunno
2 And no need for semicolons in python

Answer: 
1. This tupple, i get it from excel range extraction.
e.g. seriesxlist = newws.Range(newws.Cells(3,2),newws.Cells(usedRows,2)).Value

2. i removed semicolon, still i am facing same error. I am unable to get multiplies values.

Please suggest. 
I have input as below tuple only.
seriesxlist1 = ((0.0,), (0.01,), (0.02,), (0.03,), (0.04,), (0.05,), (0.06,), (0.07,), (0.08,), (0.09,), (0.1,), (0.11,))

The cause of the error is easy enough.

(0.0,) * (0.0,) is undefined.  It's unclear however what you
 actually intended because the problem is incompletely specified.
 

Start with python version.  I'll assume 3.3.

Next show us what result you actually expect. Can we assume all
 tuples will have a single element in them? Are you looking to
 flatten both list and tuples,  and get a single float
 sum?

Wild guess:

x2 = [x[0]* x[0] for x in seriesxlist1];
res = sum (x2)
