Having a difficult time resolving "TypeError: 'list' object is not callable" issue

Error:

Traceback (most recent call last): File "/root/PycharmProjects/Capstone2/main", line 207, in for paramIndex in range(0, 4): TypeError: 'list' object is not callable

During handling of the above exception, another exception occurred:

Traceback (most recent call last): File "/root/PycharmProjects/Capstone2/main", line 249, in print('stream ending') File "/usr/lib/python3/dist-packages/picamera/camera.py", line 758, in exit self.close() File "/usr/lib/python3/dist-packages/picamera/camera.py", line 737, in close self.stop_recording(splitter_port=port) File "/usr/lib/python3/dist-packages/picamera/camera.py", line 1198, in stop_recording encoder.close() File "/usr/lib/python3/dist-packages/picamera/encoders.py", line 431, in close self.stop() File "/usr/lib/python3/dist-packages/picamera/encoders.py", line 815, in stop super(PiVideoEncoder, self).stop() File "/usr/lib/python3/dist-packages/picamera/encoders.py", line 419, in stop self._close_output() File "/usr/lib/python3/dist-packages/picamera/encoders.py", line 349, in _close_output mo.close_stream(output, opened) File "/usr/lib/python3/dist-packages/picamera/mmalobj.py", line 371, in close_stream stream.flush() ValueError: flush of closed file

Relevant Code: 

angle = []
distance = []
speed = []
current = []
timestamp = []
parameterList = []
parameterList.extend((angle, distance, speed, current, timestamp))                

            for paramIndex in range(0, 4): # LINE 207
                # Select Range
                range = getRange(index, paramIndex + 5)
                cell_list = sheet.range(range[0], range[1], range[2], range[3])

                cellIndex = 0

                for cell in cell_list:
                    try:
                        cell.value = parameterList[paramIndex][cellIndex]
                    except:
                        print("PI: " + str(paramIndex))
                        print("CI: " + str(cellIndex))
                        print("PL LEN: " + str(len(parameterList)))
                        print("P LEN: " + str(len(parameterList[paramIndex])))

My Thoughts:

The error makes me think that paramIndex is a list and not an integer but the code executes fine for the first four iterations. This makes me think that there is something wrong with my last list (timestamp). The only thing that I can imagine being wrong with my last list is some sort of index out of bounds issue but...
The except block is never hit
The largest value cellIndex reaches is 30 (expected)
The length of parameterList is 5 (expected)
The length of timestamp is 31 (expected)

I am stumped. If anyone can offer some help that would be greatly appreciated.

paramIndex is fine but you need to avoid calling variables the same name as your functions. In this case, range() is a standard python function but you create a variable called 'range'. Thereafter if you tried to use the range function you'd get an 'object is not callable' error because it's trying to use your range object as the standard range function.

If you insist on wanting to keep the range object name then use xrange() instead of range() where you define your for loop and you shouldn't get any conflicts.
