TypeError: list indices must be integers or slices, not list
Also, as this may happen frequently, note that you cannot access slices of lists (but you can for an array):
import numpy as np
integerarray = np.array([33,11,22], dtype=int)
integerlist = [33,11,22]
indexArray = [1,2,0] # or equivalently, an array, e.g. np.argsort(integerlist)
print(integerarray[indexArray]) ## works fine
print(integerlist[indexArray]) ## triggers: TypeError: list indices must be integers or slices, not list
I hope this helps. It even happened to me that I had to convert to a float array, otherwise the object would remain of the wrong type.
This is a classic mistake. i
in your case is already an element from array
(i.e. another list), not an index of array
(not an int
), so
if Volume == i[2]:
counter += 1
You can check the Python tutorial. Also, try doing this:
for i in array:
print (i)
And see what you get!
Also I would advise to stick to naming conventions: variables are normally lower-case (volume
, not Volume
). In this case i
is misleading. row
or elem
would be much more suitable.
