Some other programming languages have varying case sensitivity; in PHP, for example, variable names are case-sensitive but function names are not case-sensitive. This means that if a function is defined in lowercase, it can be called in uppercase, but if a variable is defined in lowercase, it cannot be referred to in uppercase.
Exception:: Class is a base class and class-maker for derived exception classes. It provides a full structured stack trace in $@ -> trace and $@ -> trace -> as_string . Fatal overloads previously defined functions that return true/false e.g., open , close , read , write , etc.
Python's runtime does not restrict access to such attributes, the mangling only prevents name collisions if a derived class defines an attribute with the same name. On encountering name mangled attributes, Python transforms these names by prepending a single underscore and the name of the enclosing class, for example: >>>
Python and Ruby both recommend UpperCamelCase for class names, CAPITALIZED_WITH_UNDERSCORES for constants, and snake_case for other names. In Python, if a name is intended to be " private ", it is prefixed by one or two underscores.
In the second example, the sequence ---[[starts an ordinary, single-line comment, so that the first and the last lines become independent comments. In this case, the print is outside comments. In this case, the last line becomes an independent comment, as it starts with --.
Snake case (sometimes stylized autologically as snake_case) is the naming convention in which each space is replaced with an underscore (_) character, and words are written in lowercase. It is a commonly used naming convention in computing , for example for variable and subroutine names, and for filenames .

There is also a new form of case label, case L-> where the right-hand-side is a single expression. This also prevents fall through and requires that cases are exhaustive. In Java SE 13 the yield statement is introduced, and in Java SE 14 switch expressions become a standard language feature. [8] [9] [10] For example:
