Piece of code from a module of the Linux kernel, which uses snake case for identifiers. 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.
String functions are used in computer programming languages to manipulate a string or query information about a string (some do both).. Most programming languages that have a string datatype will have some string functions although there may be other low-level ways within each language to handle strings directly.
Similarly, lower camel case (also known as dromedary case) requires an initial lowercase letter. Some people and organizations, notably Microsoft, use the term camel case only for lower camel case, designating Pascal case for the upper camel case. [4] Some programming styles prefer camel case with the first letter capitalized, others not.
The lower-case "a" and upper-case "A" are the two case variants of the first letter in the English alphabet.. Letter case is the distinction between the letters that are in larger uppercase or capitals (more formally majuscule) and smaller lowercase (more formally minuscule) in the written representation of certain languages.
For example, in Python, raw strings are preceded by an r or R – compare 'C:\\Windows' with r'C:\Windows' (though, a Python raw string cannot end in an odd number of backslashes). Python 2 also distinguishes two types of strings: 8-bit ASCII ("bytes") strings (the default), explicitly indicated with a b or B prefix, and Unicode strings ...
Alternating caps, [1] also known as studly caps [a], sticky caps (where "caps" is short for capital letters), or spongecase (in reference to the "Mocking Spongebob" internet meme) is a form of text notation in which the capitalization of letters varies by some pattern, or arbitrarily (often also omitting spaces between words and occasionally some letters).
In Python, if a name is intended to be "private", it is prefixed by one or two underscores. Private variables are enforced in Python only by convention. Names can also be suffixed with an underscore to prevent conflict with Python keywords. Prefixing with double underscores changes behaviour in classes with regard to name mangling.
In other words, it does not matter whether the key would have produced an upper-case or a lower-case letter. The interpretation of the control key with the space, graphics character, and digit keys (ASCII codes 32 to 63) varies between systems. Some will produce the same character code as if the control key were not held down.
