Is there a way of naming conventions for a specific identifier?

So I have been set this task for revision and I am unsure as to what the question is implying:

Because identifiers in a programming language cannot contain any spaces, programmers use conventions when stating the names of variables and subroutines. Popular conventions include PascalCase (used in these tutorials), camelCase, kebab-case and snake_case. Write a function that takes three parameters, the two parts of an identifier, the convention required and outputs the identifier.​

E.g. Shields Up in kebab-case: shields-up - All letters are in lowercase. Each word is separated with a dash.​

snake_case shields_up - All letters are in lowercase. Each word is separated with an underscore​

camelCase: shieldsUp - All letters are in lowercase except the first letter of the second word.​

PascalCase: ShieldsUp - Only the first letter of each word is in uppercase.

I assume that the code is asking for the identifier to be displayed in each of these conventions. I have tired looking up ways to turn a string into camelCase but that is as far as I have got.

If anyone has any ideas, please let me know! Thanks

Solution

  • Off the top of my head, a simple approach for camelCase would be:

    >>> def conventionalIdentifier(str1, str2, convention):
...   if(convention == 'camelcase'):
...     return str1.lower() + str2.capitalize()
...   else: #similarly for the rest
...     pass
...
>>> print(conventionalIdentifier('hello', 'there', 'camelcase'))
helloThere

    From what I gather, the question specifies that you take two parts of an identifier, i.e. you just have to put two strings together in a particular format.
