Using Python:

Part 1:

Write the following function in a file called listlab.py

list4(): This function takes four formal parameters. If all four inputs are of type int and/or float, return the largest of the four inputs. Otherwise, return a list containing the four input parameters. Remember the type() function from Chapter 2.2; you may also want to use max().

Notes:

Every function must have a docstring, and variable names other than input parameters and loop control variables must have meaningful names. We will be grading for this.
Do not put a call to your function at the bottom of the file.

Part 2:

Write a Python function `make_triangle(trianglechar, triangleheight) that will return a string with an isosceles right triangle based on the two formal parameters triangle_height giving the triangle height and triangle_char that gives the symbol to be printed.

Important notes:

This program returns (not prints!) a string.
For this function and the other part of this lab you are required to put in a docstring. That will be checked by a TA/grader reading the program.
Every one of the occurrences of triangle_char should have a single space after it, including the ones at the ends of lines.
This is not too complex to write either using while or using for and range(). If you're comfortable with for() and range(), that might be a little easier.
The two ways we thought of to do this are either using two loops, one nested inside the other, or using one loop and string multiplication.
`\n' is the newline character. Your returned string should have triangle_char of them. (One at the end of every "line".)

Expert Solution

def list4(a, b, c, d):
        permittedtype = [int, float]
        if type(a) in permittedtype and type(b) in permittedtype and \
                type(c) in permittedtype and type(d) in permittedtype:
                return max(a, b, c, d)
        else:
                return [a, b, c, d]

def make_triangle(trianglechar, triangleheight):
        i = 1
        s = ''

        while i <= triangleheight:
                s += trianglechar * i + '\n'
                i += 1
        
        return s.strip()

Write a Python program in a file called consonants.py, to solve the following problem using a nested loop. For each input word, replace each consonant in the word with a question mark (?). Your program should print the original word and a count of the number of consonants replaced. Assume that the number of words to be processed is not known, hence a sentinel value (maybe "zzz") should be used. Sample input/output: Please enter a word or zzz to quit:...
