How to compute the area and format it in a table?

This is my homework:

Write a program that computes the area of a square, triangle, circle, and a rectangle. The program then prints the output in nicely formatted table as shown in the example below. Your program should be implemented with at least 3 function and docstrings. You should create a new module “area_tools” with the following functions in it: Square(base), Triangle(base,height), Circle(radius), and Rectangle(base,height). Your main program should use the functions in your module.

Example of the table:

Vars | square | Triangle | circle | rectangle

10,10 | 100 | ??? | 345.56 | 4567

I know I did it wrong and I don't know how to go from here. I get an error message saying:

TypeError: Square() missing 1 required positional argument: 'base'

I really don't know what to do. This is what I've done so far. In a file named area_tools.py, I did this:

 def Triangle():
    '''Finds the area of the triangle'''
    base = int(input("Enter the base: "))
    height = int(input("Enter the height: "))
    triangle_area = (base * height) / 2
    return triangle_area

def Rectangle():
    '''Finds the area of the rectangle'''
    base = int(input("Enter the base: "))
    height = int(input("Enter the height: "))
    rectangle_area = base * height
    return rectangle_area

def Circle():
    '''Finds the area of the circle'''
    radius = int(input("Enter the radius: "))
    pi = 3.14159
    circle_area = pi * radius ** 2
    return circle_area

def Square():
  base = int(input("Enter the base: "))
  square_area = base ** 2
  return square_area

In a second file, I did this:

import area_tools
import pandas as pd

data = {'square': [Square()],
        'triangle': [Triangle()],
        'circle': [Circle()],
        'rectangle': [Rectangle()],
        }

df = pd.DataFrame(data,columns=['square', 'triangle', 'circle','rectangle'])
df

EDIT: I copied and pasted the code on here so it's easier to see what I'm talking about: https://repl.it/@fgffdsfj/StrangeInfantileDisks#main.py

You should use input() outside your functions and send values as arguments

def Triangle(base, height):
    '''Finds the area of the triangle'''
    return base * height / 2

def Rectangle(base, height):
    '''Finds the area of the rectangle'''
    return base * height

def Circle(radius):
    '''Finds the area of the circle'''
    pi = 3.14159
    return pi * radius ** 2

def Square(base):
    return base ** 2

my_base   = int(input("Enter the base/width/radius: "))
my_height = int(input("Enter the height: "))
#my_radius = int(input("Enter the radius: "))

# only for fast test
#my_base   = 3
#my_height = 4

result_square = Square(my_base)
result_triangle = Triangle(my_base, my_height)
result_circle = Circle(my_base)
result_rectangle = Rectangle(my_base, my_height)

And later you can use string formatting (align to left, right or center) to create table.

print('| {:^7} | {:^10} | {:^10} | {:^10} | {:^10} |'.format('Vars', 'Square', 'Triangle', 'Circle', 'Rectangle'))
print('| {:>3},{:<3} | {:^10} | {:^10} | {:^10} | {:^10} |'.format(my_base, my_height, result_square, result_triangle, result_circle, result_rectangle))

Result

|  Vars   |   Square   |  Triangle  |   Circle   | Rectangle  |
|   3,4   |     9      |    6.0     |  28.27431  |     12     |

In the Second file when you call function your didn't send any argument to function that why it return an error

You can remove argument to function in First file and get from input instead

def Triangle():
    '''Finds the area of the triangle'''
    base = int(input("Enter the base: "))
    height = int(input("Enter the height: "))
    triangle_area = (base * height) / 2
    return triangle_area

def Rectangle():
    '''Finds the area of the rectangle'''
    base = int(input("Enter the base: "))
    height = int(input("Enter the height: "))
    rectangle_area = base * height
    return rect_area

def Circle():
    '''Finds the area of the circle'''
    radius = int(input("Enter the radius: "))
    circle_area = pow(math.pi * radius, 2)
    return circle_area
