Final answer:
The given function, camel_case, takes a string parameter var_name which represents a variable name with underscores separating words. It returns the variable name in camel case format.
Step-by-step explanation:
The given function, camel_case, takes a string parameter var_name which represents a variable name with underscores separating words. It returns the variable name in camel case format. If var_name consists only of underscores, an empty string is returned.
In camel case, the first letter of each word, except the first one, is capitalized and all the underscores are removed. For example, camel_case('to_ca-el_case') returns 'toCamelCase'.
To implement this, we can split the string by underscores, capitalize each word except the first one, and then join the words together to form the camel case variable name.
The camel_case function converts a snake_case variable name string to camelCase by capitalizing the first letter of each word after the first and removing underscores. If the input only contains underscores or non-alphabetic characters, an empty string is returned.
The camel_case function you're referring to is designed to convert a string representing a variable name from snake_case to camelCase. To achieve this, it typically takes a string with words separated by underscores, and converts it into a string where the first letter of each subsequent word after the first is capitalized and the underscores are removed.
Here's a general approach to implementing such a function:
- Split the input string by underscores.
- Capitalize the first letter of each word except the first one.
- Concatenate all words back into a single string.
If there are only underscores or non-alphabetic characters in the input string, an empty string is returned. Non-alphanumeric characters, or numbers in parts of words, must be handled according to the specifications of your function, which could include removing them or leaving them as they are, depending on the desired camelCase format.
