Question

Python 3 Functions that give answers

Define and complete the functions described below.
* function name: get_name
* parameters: none
* returns: string
* operation:
Here, I just want you to return YOUR name.
* expected output:

JUST RETURNS THE NAME...TO VIEW IT YOU CAN PRINT IT AS BELOW
>>> print(get_name())
John

* function name: get_full_name
* parameters: fname (string)
lname (string)
first_last (boolean)
* returns: string
* operation:
Return (again, NOT print) the full name based on the first and last names
passed in as arguments. The first_last argument will be True if you should
return the name as <fname lname> and False if you shoudl return the name
as <lname, fname>.
* expected output:

# just return the name
>>> print(get_full_name("John","Doe",True))
John Doe
>>> print(get_full_name("John","Doe",False))
Doe John
* function name: get_circle_area
* parameters: radius (float)
* returns: float
* operation:
Return the area of a circle with the given radius. Use 3.14 as Pi. And Google if for
some reason you've forgotten how to get the area of a circle.
* expected output:

Just return the value
>>> print(get_circle_area(5.0))
78.5
>>> print(get_circle_area(2.5))
19.625

Answer 1

Hopefully all yours doubt will clear if you have left with any doubt please let me know in comment. I will try my best to resolve that.

Here i am posting code and screenshot of program so that you have a clear idea about indentation and output with it.

Code :-

# Function will return name (John)
def get_name():
    # store name in variable name which will be return to main function
    name = "John"
    return name

# Function will return full name based on first and last name
def get_full_name(fname, lname, first_last):
    # If value of first_last is True means first name come first in full name then last name
    if first_last:
        # string concatenation of first name, space and last name
        return (fname + " " + lname)
    # If value of first_last is False means last name come first in full name then first name
    else:
        # string concatenation of last name, space and first name
        return (lname + " " + fname)

# Function will calculate area of circle
def get_circle_area(radius):
    # calculate area and store in area variable
    area = 3.14 * radius * radius
    # return  area of circle to main function
    return  area

# print name using get_name function
print(get_name())

# print full name using get_full_name function
print(get_full_name("John","Doe",True))
print(get_full_name("John","Doe",False))

# print area of circle using get_circle_area
print(get_circle_area(5.0))
print(get_circle_area(2.5))
