We need more, or at least I would have needed for the rest of this semester

Thank you for this excellent video. Shame that the announced further videos apparently have come to naught, but I know how it is....

Excellent videos, I just subscribed. Thank you!

Great videos on this topic! More videos like this one are very welcome! Especially how to translate python functions and procedures into java!

Love the course! I thought that the transition would be much harder before watching the video. Looking forward to the next videos in the series. Thanks professor!

With python you don't actually need to tell it the type of varible you are creating. It figures that out automatically based on weather the value is sourrounded in quotations or not. Like number = 1 would automatically be an int. And number = "1" would automatically be a string.

To be honest I pretty much use single-statement ifs whenever possible in Java (and other C-style languages) since it usually fine when in the right context and (imo) the code looks cleaner. Though, it would be a lot nicer if Java and other languages took the Ruby route and allowed for single line ifs (like `puts "x is more than 5" if x > 5`, which does what you think it does).

Man, that command line app thing and set args to 5 thing is really confusing, I have a hard time replicate with VS Code.

So, for programming languages like python and Java when we use types like int and string. Is the program accessing some manually created type class that was coded into the language? Or are those types inherent to the computer?
