Try catch statements in C
...atch clauses allowed you to catch exceptions (like dividing by zero). This function seems to only allow you to catch exceptions that you throw yourself.

Python's equivalent of && (logical-and) in an if-statement
...lt, then the second operator isn't evaluated at all.
To show this I use a function that simply takes a value, prints it and returns it again. This is handy to see what is actually
evaluated because of the print statements:
>>> def print_and_return(value):
... print(value)

Is “argv[0] = name-of-executable” an accepted standard or just a common convention?
...
Guesswork (even educated guesswork) is fun but you really need to go to the standards documents to be sure. For example, ISO C11 states (my emphasis):
If the value of argc is greater than zero, the string pointed to by argv[0] represents the program name; argv...
Can the :not() pseudo-class have multiple arguments?

Accessing an array out of bounds gives no error, why?
...(although it does not forbid it either). A vector also has the at() member function which is guaranteed to perform bounds-checking. So in C++, you get the best of both worlds if you use a vector. You get array-like performance without bounds-checking, and you get the ability to use bounds-checked ac...
