I was working on a web scraping project last month and this is where I got stuck.
Something about the coding/encoding wasn't working... but I had no clue then what the problem was or what it meant.

This course is brilliant - really motivating me to keep going as I can see the progress in my knowledge!

ascii - maps characters to integers e.g. lower case a -> 97 (easy)
unicode - python's mapping standard e.g. utf-8 (hard)
string (unicode) -> encode (utf-8) -> send -> socket -> recv -> decode (unicode)

miss unicode/utf-32 were used..instead of ascii being used with 8bits or 1 byte per character..it would be 4 bytes or 32 bits and 4 times larger...

I am a fan of yours. Good work.
Arduino sends data to Python as <type(Unicode)> .
In Python;
the data is integers and I need it as integers. I am quite sure that unicode includes whitespace.

I have seen this work: data_from_arduino = int(data_from_arduino) but now it does not.

Treating the Unicode like a string does not seem to work. (like breaking it apart)

lstrip(data_from_arduino) does not work. Any ideas.
