Here\'s the question:

Given a list of items in Python, how would I go by to get all the possible combinations of the items?

Answer 1

just thought i'd put this out there since i couldn't fine EVERY possible outcome and keeping in mind i only have the rawest most basic of knowledge when it comes to python and there's probably a much more elegant solution...(also excuse the poor variable names

testing = [1, 2, 3]

testing2= [0]

n = -1

def testingSomethingElse(number):

try:

    testing2[0:len(testing2)] == testing[0]

    n = -1

    testing2[number] += 1

except IndexError:

    testing2.append(testing[0])

while True:

n += 1

testing2[0] = testing[n]

print(testing2)

if testing2[0] == testing[-1]:

    try:

        n = -1

        testing2[1] += 1

    except IndexError:

        testing2.append(testing[0])

    for i in range(len(testing2)):

        if testing2[i] == 4:

            testingSomethingElse(i+1)

            testing2[i] = testing[0]

i got away with == 4 because i'm working with integers but you may have to modify that accordingly...
