Coding and IDE

[prodrumernate]

i learn better by writing and doing than just reading.im using sololearn to learn python.i couldnt even write the code for a simple calculator..so i think the best thing to do is start with a simple code and go from there.i have several raspberrypis to work with.but need to know what codes are easist to write as well as an IDE to check and test the codes?

thank you all in advance
