In Python whitespace is significant. The function ends when the indentation becomes smaller (less). Note that one-line functions can be written without indentation, on one line: And, then there is the use of semi-colons, but this is not recommended: The three forms above show how the end of a function is defined syntactically. As for the semantics, in … Read more
The line getMenuInflater().inflate(R.menu.menu_quiz, menu); is a short form of this:
PHP parser errors take some getting used to; if it complains about an unexpected ‘something’ at line X, look at line X-1 first. In this case it will not tell you that you forgot a semi-colon at the end of the previous line , instead it will complain about the if that comes next. You’ll … Read more
This line is your problem: Python interprets what’s in those square brackets as a key to get an item from what’s just before them—in this case, getting the item with key “ram”, “bak”, … from list. And, of course, the list class isn’t a container and doesn’t have any items! Remove the leading list, and … Read more
It’s a shorthand for <?php echo $a; ?>. It’s enabled by default since 5.4.0 regardless of php.ini settings.
You need to place all statements after the declarations in a code block, e.g. method rather than the class block. Logically it probably makes sense to place all statements in the code block but the non-declarative statements need to be enclosed within the new block
As the markdown documentation states, it is fine to use HTML if you need a feature that is not part of Markdown. HTML5 supports Expand snippet Else you can use span as suggested by Rad Lexus
The and keyword is used either to avoid multiple let (first example, I never use it for this but why not) or for mutually recursive definitions of types, functions, modules… As you can see in your second example : debug calls debugl and vice versa. So the and is allowing that. [EDIT] It bothered me … Read more
Semantics is about meaning. It includes: the static semantics, which is the part that can be ascertained at compile time, including data typing, whether all variables are declared, which declaration applies to which variable in the case of scoping, what their type is, whether functions and methods are called with correct calling sequences, whether assignments … Read more
Short story: The 0 tells the parser it’s dealing with a constant (and not an identifier/reserved word). Something is still needed to specify the number base: the x is an arbitrary choice. Long story: In the 60’s, the prevalent programming number systems were decimal and octal — mainframes had 12, 24 or 36 bits per byte, which is nicely divisible by 3 = … Read more
