How a function is given a name?

Question

Which name is given a function that is separated by undescore. function_name.

And to a function like FunctionName? and what would be the right one for python and ANSI C.??

It gets named `function_name`, simple as that. Which style to use is optional, use one and stick to it. There was some very interesting scientific report somewhere though (citation needed), which found out that programs written in camel case were less readable by the human brain. — Lundin, Apr 17 '18 at 14:41

@Lundin: That proves I have a human brain. All those years of doubting are over! — Bathsheba, Apr 17 '18 at 15:08
Found it! "An Eye Tracking Study on camelCase and under_score Identifier Styles" www.cs.kent.edu/~jmaletic/papers/ICPC2010-CamelCaseUnderScoreClouds.pdf. Quite a serious study! — Lundin, Apr 17 '18 at 15:33

Function names like func_one are written in snake case, while functions written like FunctionOne are written in Pascal case, which is a subset of Camel case where the first letter is also uppercase.

Thanks to @abelenky for pointing out the initial error.

I've heard `FunctionOne` described as "Pascal Case", and `functionOne` would be "Camel Case" (because it has a "hump" in the middle). – abelenky Apr 17 '18 at 15:18
I call `FunctionOne` "Upper Camel Case" but I'm not sure if that's a "standard" name for it. – Kevin Apr 17 '18 at 15:19
@abelenky you're absolutely right, I made an error there. Will update. – Colin Ricardo Apr 17 '18 at 15:26
@Kevin that's called Pascal Case :) – Colin Ricardo Apr 17 '18 at 15:28
@Colin [wikipedia](https://en.wikipedia.org/wiki/Camel_case) says that upper camel case is a valid name for it too. I wasn't saying that Pascal Case was wrong, just that upper camel case is another name. – Kevin Apr 17 '18 at 15:31
@Kevin you're right, the two seem to be interchangeable :) – Colin Ricardo Apr 17 '18 at 15:33

function_name is called a Snake Case. It is the recommended casing for Python. See this answer for more enlightenment.

In before someone makes the Dromedary language, where the recommended style is camel case. – Lundin Apr 17 '18 at 14:42
@Lundin OCaml ;) – Kamila Szewczyk Apr 17 '18 at 14:52
@KrzysztofSzewczyk Ach, all my bad ideas are already taken :( – Lundin Apr 17 '18 at 15:05
@Lundin I'm sorry :( – Kamila Szewczyk Apr 17 '18 at 15:14
