I'm a bit confused, doesn't the post say "I studied Computer Science at college"? So the poster studied and has a CS degree and yet it took them '7 months' to learn Python?
Not sure how this is confusing. Studying Computer Science at college != programming proficiency. I'm finishing up my last college class (online University) will graduate with B.S. in CS Major S.E. got good grades in both C++, Java, and CS related classes and I have been attempting to get better at Python for the better part of a year now and still don't know shit and would hardly qualify my self as a web developer let alone a software engineer.
I understand your confusion, but during my studies I learned different language and I was rushing to catch up with other students. I feel like, I learned more during my self studies than college.
