I would dive straight into C, if I were you. No sense in waiting just to learn it in the future. Python is being used less in the work environment from what I understand(probably gunna get flammed for saying that
), unless you have other personal reasons besides using it as a stepping stone to C.
As for getting a mentor... I personally don't think anyone would want to mentor someone without personal gain, hence why teachers get paid money. I would suggest reading a nice ebook or taking some college classes, because like I said teachers are mentors and want to help you learn. Friends on CodingForums or random community members are willing to kindly help you when you have a problem or don't understand something. Having all 3 in your arsenal(ebooks, classes, forums) is the best way of learning a programming language.
one C ebook: don't know if free or its a pirated ebook
Anyone else have something to suggest to him?
