hi all,
f1 =
f2 =
f = f1 - f2
i need a output like f = [0.1,0.2,-0.1]
but wen i run this program it is showing error like
TypeError: unsupported operand type(s) for -: 'list' and 'list'
thanks in advance.........

Jump to PostYou have at least two problems:
- The types of your list elements are strings.
- The list type doesn't have operator minus defined on it
To solve the first problem, just make the list items be floats or whatever: Skip the quotes
To solve the second problem, …
Jump to PostConvert the list values to int/float data type. Then it will be easy to work with them. Eg....
Flist1 = [float(x) for x in f1] Flist2 =[float(x) for x in f2]
Now you can check for the diff. Btwn the lists.
result = [] …
You have at least two problems:

To solve the second problem, you can iterate over the lists in a variety of ways.
result = []
for index in range(len(l1):
# do something useful with l1[index], l2[index] and result
What happens in either case if the lists are not the same length? What should you do about that possibility?

Coming from my htc phone. Hope you get the idea :)
thanks for a reply
Flist1 = [float(x) for x in f1]
Flist2 =[float(x) for x in f2]
result = []
for x in len( Flist1):
result.append(Flist1[x]-Flist2[x])
wen i run this program it is showing error like:
Traceback (most recent call last):
File "C:/Users/kavya/Desktop/k.py", line 13, in -toplevel-
for x in len( Flist1):
TypeError: iteration over non-sequence
Length is simple number and can not be iterated. You need one function starting with r or x to produce sequence of values.
ow sorry... do this.....
result = []
for x in range(len( Flist1)):
result.append(Flist1[x]-Flist2[x])
thanks a lot richieking it is working fine........
