How do I insert a list into my python code using Cocalc / Sagemath

Unfortunately, Input() doesn't work in a .sagews, because every integer in a list is then surrounded by an Integer(Insert list value here), which of course breaks the program.

I want to be able to input a list of integers into the sorting algorithm, so that I could actually utilize Cocalc and SageMath. Any help would be greatly appreciated!

When in the .sagews, I do:

load('')    **or attach('')**

driver(2,4,5,1)        **or driver([2,4,5,1])**

The output:

Error in lines 1-1
Traceback (most recent call last):
  File "/cocalc/lib/python3.11/site-packages/smc_sagews/", line 1244, in execute
  File "", line 1, in <module>
  File "/cocalc/lib/python3.11/site-packages/smc_sagews/", line 3823, in attach
  File "/cocalc/lib/python3.11/site-packages/smc_sagews/", line 3919, in load
  File "<string>", line 1, in <module>
  File "sage/misc/persist.pyx", line 175, in sage.misc.persist.load
    sage.repl.load.load(filename, globals())
  File "/ext/sage/10.2/src/sage/repl/", line 253, in load
    exec(code, globals)
  File "./", line 217, in <module>

Infinite recursion continues, most likely because nothing was inputted into driver([])

I've tried inputting driver([Insert list values here]), driver(Insert list values here), but I just keep getting a wide variety of errors.

My code below works perfectly fine in Visual Studio Code, and sorts any given list inserted into driver([]) towards the very bottom This is only a fragment:

def driver(theInput = []):
    global inputList 
    global copy
    global copy2
    global inputStr
    global original 

    good = 0

    # First iteration, other part of driver is therefore unnecessary. 

    if iterationCount == 0:

        inputList = theInput


        # Copies are necessary, because deleting old lists means deleting parts of the list history, 
        # and future inputList
        copy = listC.copy()
        copy2 = listC.copy()

        # Writes down elements from copy2 to the inputList. 
        # Instead of EX: inputLit = [[1,2,3]], it does: inputList[1,2,3]
        j = 0
        for j in range(len(copy2)):
            inputList.insert(len(inputList), copy2[0])

        # Compares the elements and sees if they are in numerical order. 
        for i in range(len(listC) - 1):

            if listC[i] <= listC[i + 1]:
                good += 1

        # List is in numerical order
        if good == len(listC) - 1: 


        # List is not in numerical order    




#Initiates the sorting algorithm

Alright, I figured it out. In SageMath / Cocalc, when making a python file, you don't have to call the function to start the program. That is alerady done when you type driver(insert value here) in the .sagews file
