Question: What are 3 or 4 hard development skills I can focus on learning in the next two months or so to make me more marketable, given my lack of real development experience?

Details: I graduated college with a compsci degree, but have been doing systems/service administration since then. Aside from some small scripts for work, I don't have any post-college development experience. And even the skills I got from college aren't phenomenal because I was convinced I would be satisfied on the admin -> engineer -> architect ladder that I'm on right now.

But things have changed. My interest has dwindled in my current field, and I want to switch into a development role.

I am extremely comfortable with the Python language, but not so much with its many frameworks for frontend and web development.

After 3 years of college, I have finally discovered the magical wonder of unit testing. All it took was me building my own application on the side to motivate myself to actually do it!
