This assignment focuses on reviewing the fundamental concepts of turtle graphics functions, data types, operators, data conversions, and loops in Python through practical implementation. Students are required to create functions that utilize turtle graphics to draw geometric shapes, explore data types and their interactions with operators, and implement loops for repetitive drawing tasks. The core objectives include understanding how turtle functions operate and how data types influence programming logic, along with developing skills in user input handling and dynamic shape creation.

Python's turtle graphics library offers an array of functions to create visual art through programming. This assignment aims to reinforce understanding of turtle functions, data types, operators, data conversion methods, and control flow using loops. The task begins by developing a function called rhombus, which uses the turtle library to draw a rhombus based on given specifications. The function must be flexible enough to accept different arguments, including the internal angle, to understand parameter passing and function invocation in Python.

First, you will create a new Python script called lab02.py. Within this script, define the rhombus function with one parameter, side_length. Use turtle commands such as forward() and right() to draw a rhombus, turning by an internal angle that can be adjusted through an additional argument. Call the rhombus function with various inputs to observe behavior with missing arguments, multiple arguments, and different internal angles. This will help you understand how Python handles function arguments and default parameters.

Next, examine how data types influence the behavior of functions by passing integers, floats, and strings to a predefined square function. By invoking the function with different data types, you can observe whether the code executes successfully or raises errors, illustrating the importance of data type compatibility. In addition, experiment with operators (+, -, , /, //, *) across combinations of integers, floats, and strings to identify how Python processes different types, noting any unexpected results or errors.

Further, you will explore data type conversions using Python’s built-in functions int(), str(), and float(). These functions convert between types to enable arithmetic operations and string concatenation, which are often problematic when combining incompatible types directly. Modify your previous short programs to correctly perform addition and division with user-inputted numbers, ensuring type conversion is applied where needed.

Finally, you will implement control flow using for loops to draw repeating patterns such as polygons with an arbitrary number of sides. Write a function polygon that takes parameters for the number of sides and side length, then draws the shape using a loop. Extend this by prompting the user to specify the size and number of sides, dynamically drawing the polygon. Experiment with various loop ranges, including zero, negative, and float values, to see their effect on execution.

Through these exercises, students will gain hands-on experience with core Python programming concepts, emphasizing practical application in graphical and computational tasks. Mastering these fundamentals prepares students for more complex programming challenges involving algorithms, data processing, and visualization.
