One of the harder things for beginners to grasp when learning a second or third programming language is that language is not just syntax. You see it all the time in Python in particular: people writing code like it's C or Java. It's no different to grabbing a French dictionary and transliterating your English sentence to French word by word. It just doesn't work and, in some cases, is completely wrong. Grokking a language means so much more than knowing the key words for doing all the stuff you used to do in your old language.
