how to pass a cell to python script and in the python script change convert to list

hi, i use the system() function in matlab to call a python script, all the python script is complete but when i send the cell in the system function i get the error : COMMAND must be a text scalar.

so, how can i send this cell to python?

Not sure what it means by "send the cell in the system function"? Returning the result from python to matlab?
