modification of a PPM image with python
I'm trying to turn a red smiley(PPM) into a green smiley(PPM) by modifying the source code with python (I use PyCharm CE).
When I print the source file, I have this :
b'P6n100 100n255nxffxffxffxffxffxffxffxffxffxff...
The goal is to modify some triplets (xffxffxff) to change pixels color. So I keep the header(P6n100 100n255n) aside and I create an array to modify just:(xffxffxffxffxffxffxffxffxffxff...)
After modification, (I turn the red pixels into green pixels) I add a new code:
[255, 255, 255, 255, 255, 255, 255, 255, 255, 255, ...
How to turn this array into the same format(Ascii) than I had at the beginning; which was (xffxffxffxffxffxffxffxffxffxff...)?
The smiley
python pycharm hex ascii ppm

Hint: what you had was not ASCII but a bytearray – look it up in the documentation.
