Question

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".) Example output for make_triangle('*', 5) is the string:

%

% %

% % %

% % % %

% % % % % or, equivalently, % \n% % \n% % % \n% % % % \n% % % % % \n Note that the last character of each of those 5 lines is a space!

Answer 1

def make_triangle(trianglechar, triangleheight):
    s = ''
    for i in range(triangleheight):
        s += (trianglechar + ' ') * (i + 1) + '\n'
    return s


# Below code is used to test the code. ignore/remove the code below
print(make_triangle('%', 5))
