Hey I was wondering if I could get some help on the camel_case(var_name) function on the second page there are some test cases as well to see if the code works just need some guidance on how to do it.

sponsibility and further with we will be using. You cases before you submit. Further testing and debugging is your It takes three list1, list2) It takes three parameters, n, list1, list2, and returns True if n is exclusively in liot1 or lintz; otherwise, it returns False. In other words, it returns True if n is in only ono of the two lists and It takes two dictionaries as parameters, dict1 and dict2 and roturns a new dictionary that combines dict1 and dict2, collecting the values of common keys in a list. > dict_extend(\{'a': 100,b ': 200, 'c': 300},{(a:300,b ' : 200, 'd' :400}) {a ': [100, 300], 'b': [200, 200], 'c': [300], 'd': [400] } > dict_extend ({1:0ne,2: Two' },{}) {1:[One],2: ['Two'] } camel_case (var name) It takes a string as a parameter, var_name, that represents a variable name with underscores separating words and returns the variable name in camel case. If var name consists only of underscores, then an empty string should be returned. format_number(num) It takes a non-negative number as a parameter and retu with commas inserted properly as thousand separator. library/function provided in python
