Geometric Operations

You are the new lead developer at PyGeo Inc., a company specializing in building software tools for architects and builders. They need a module for their latest software that calculates the area and perimeter of various geometrical shapes, including circles, squares, rectangles, and triangles.

The new module should be named geometry_operations and should include functions to calculate the area and perimeter for each shape. To keep the code organized and scalable for future additions, each shape should be defined in a separate file.

There's a catch: the architects and builders will input data through a separate module main.py, and the output will also be handled automatically by this module. You are only responsible for the calculations and returning the results:

1. The circle.py file should include functions to calculate the area and perimeter of a circle. The function to calculate the area should be named calculate_circle_area and take the radius as an argument. The function to calculate the perimeter (also known as the circumference) should be named calculate_circle_perimeter and take the radius as an argument.

2. The square.py file should include functions to calculate the area and perimeter of a square. The function to calculate the area should be named calculate_square_area and take the side length as an argument. The function to calculate the perimeter should be named calculate_square_perimeter and take the side length as an argument.

3. The rectangle.py file should include functions to calculate the area and perimeter of a rectangle. The function to calculate the area should be named calculate_rectangle_area and take the length and width as arguments. The function to calculate the perimeter should be named calculate_rectangle_perimeter and take the length and width as arguments.

4. The triangle.py file should include functions to calculate the area and perimeter of a triangle. The function to calculate the area should be named calculate_triangle_area and take the base and height as arguments. The function to calculate the perimeter should be named calculate_triangle_perimeter and take the lengths of the three sides as arguments.

Import all the functions from all the files inside geometry_operations/__init__.py file to make it accessible from the main.py without any additional imports.

Note: You can assume that all inputs are valid, i.e., positive numbers.
