I accidentally created an infinite recursion. The error referenced pickling but I did not import pickle. 

To reproduce: 
def permute(inputList):
    '''permute(inputList) -> list
    returns list of all permutations of inputList
    CURRENTLY DOESN'T ACTUALLLY WORK PROPERLY'''
    for i in range(len(inputList)-1):
        tempList = inputList[:-i-2]
        tempList.append(inputList[-1])
        for num in inputList[-i-2:-1]:
            tempList.append(num)
        print(tempList)
        permute(tempList)  # runs infinitely (whoops)
    print()

permute([1,2,3,4])

Error thrown: 
Traceback (most recent call last):
