Ditto courses on Udemy, personally I find it best to do something structured until the stabilisers can come off rather than pick and choose from here and there.
I haven't done a Python course but I transfered from VB6 to C# with a Udemy course. Lots of free stuff but I went for paid, wasn't much, about 20 quid I think. Doing one course a year on something really helps to keep the grey matter oiled keeps you moving forward. Good luck with whatever you find Leeds1919.
