How can I multiply all items in a list together with Python?

Python 3: use functools.reduce:

>>> from functools import reduce>>> reduce(lambda x, y: x*y, [1,2,3,4,5,6])720

Python 2: use reduce:

>>> reduce(lambda x, y: x*y, [1,2,3,4,5,6])720

For compatible with 2 and 3 use pip install six, then:

>>> from six.moves import reduce>>> reduce(lambda x, y: x*y, [1,2,3,4,5,6])720

python list multiplication

You can use:

import operatorimport functoolsfunctools.reduce(operator.mul, [1,2,3,4,5,6], 1)

See reduce and operator.mul documentations for an explanation.

You need the import functools line in Python 3+.

python list multiplication

I would use the numpy.prod to perform the task. See below.

import numpy as npmylist = [1, 2, 3, 4, 5, 6] result = np.prod(np.array(mylist))
