Extracted text: Create a Python function, called number (LolCaracteres), which takes a LolCaracteres list as a parameter, and which returns a string of characters. The elements of the LolCaracteres list are all of type string (str). These strings can contain characters which are positive integers such as '10' or '3' or else characters which are not positive integers (such as letters of alphabets, special characters, etc.). The return string consists of all the elements in the list that are not positive or zero integers, as well as the sum of positive or zero elements. If there is no positive or zero element then this sum will be zero. Use isdigit () to test whether an item in the list is a positive or zero integer. The program should not crash due to type conversions. Respect the type contract of the function: (list) -> str
