String error

[Kurta]

When you have a regular string, you pass in another string object as text to split on.

>>> "split this, string, on the, commas".split(",")
['split this', ' string', ' on the', ' commas']

But if instead of a string you have a bytes object, this won't work.

>>> b"split this, string, on the, commas".split(",")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: a bytes-like object is required, not 'str'

Your arduinoStringis a bytes object. So to split it, the argument has to be a bytes object as well. Instead of ",", use b"," OR convert it to a string and split it as normal.

>>> arduinoString = b"split this, string, on the, commas"
>>> arduinoString.split(b",")  # split directly on the bytes object
[b'split this', b' string', b' on the', b' commas']

>>> arduinoString.decode().split(",")   # decode to str, then split the str
['split this', ' string', ' on the', ' commas']

Note the result of the split is a list of bytes objects,

This is actually what i needed and worked. I had convert to a number because the tutorial i was following.. puts this into a matplot chart and that was my goal.

for any one else trying to do this here is the link ..Arduino-python to matplot
Note: I use Anaconda with python 3.7 this seems to work for me up to this point. in the tutorial he uses 2.7.
