How is a (generic) function defined in the Python programming language? The contour plot differs from the contourf plot, which is what we are looking for

use c++ programming language to create a derived, or child class for Cylinder, that is, a Cone class. The same function, with the same parameters, is used. However, the formula is different for a cone. // The formula is: V = (1/3) * pi * (r^2) * h

python help... Write a function justVowels() that takes a string as a parameter and returns a new string that contains all the vowels found in the parameter string. The vowels in the returned string should appear in the same order as they did in the parameter string. A vowel is one of a, e, i, o, or u. both the upper- and lower-case vowels should be included. The characters in the returned string should have the same capitalization as they did in the parameter string. If the function is given a string without any vowels or an empty string, it should return the empty string. Use the if-else condition with iterate loop pattern. Don’t forget to include the docstring and comments.    How it should run... >>> justVowels('Did you include your collaboration statement') 'iouiueouoaoaioaee' >>> justVowels('If you did not include your collaboration statement no points') 'Iouioiueouoaoaioaeeooi' >>> justVowels('1,2,3,4,...') '' >>> justVowels('') ''
