Zodiac Sign Predictor

Abstract

Zodiac Sign Predictor is a Python project that predicts zodiac signs based on birth dates. The application features date parsing, sign calculation, and a CLI interface, demonstrating best practices in automation and user interaction.

Prerequisites

• Python 3.8 or above
• A code editor or IDE
• Basic understanding of date parsing and user input
• Required libraries: None (standard library only)

Before you Start

No external libraries required.

Getting Started

Create a Project

1. Create a folder named zodiac-sign-predictor.
2. Open the folder in your code editor or IDE.
3. Create a file named zodiac_sign_predictor.py.
4. Copy the code below into your file.

Zodiac Sign Predictor

class ZodiacSignPredictor:
    def __init__(self):
        self.signs = [
            (1, 20, 'Aquarius'), (2, 19, 'Pisces'), (3, 21, 'Aries'), (4, 20, 'Taurus'),
            (5, 21, 'Gemini'), (6, 21, 'Cancer'), (7, 23, 'Leo'), (8, 23, 'Virgo'),
            (9, 23, 'Libra'), (10, 23, 'Scorpio'), (11, 22, 'Sagittarius'), (12, 22, 'Capricorn')
        ]

    def predict(self, month, day):
        for m, d, sign in self.signs:
            if (month == m and day >= d) or (month == m % 12 + 1 and day < self.signs[m % 12][1]):
                print(f"Zodiac sign: {sign}")
                return sign
        print("Invalid date.")
        return None

    def demo(self):
        self.predict(3, 25)
        self.predict(7, 30)

if __name__ == "__main__":
    print("Zodiac Sign Predictor Demo")
    predictor = ZodiacSignPredictor()
    predictor.demo()

Example Usage

Run zodiac predictor

python zodiac_sign_predictor.py

What it produces

Running the file exactly as it ships takes 0.1 s and prints:

python zodiac_sign_predictor.py

Zodiac Sign Predictor Demo
Zodiac sign: Aries
Zodiac sign: Leo

How it fits together

Read from the top: this is what runs when you execute the file, and which function calls which. It is generated from the code, so it cannot drift from it.

Explanation

Key Features

• Date Parsing: Parses birth dates from user input.
• Sign Calculation: Determines zodiac sign based on date.
• Error Handling: Validates inputs and manages exceptions.
• CLI Interface: Interactive command-line usage.

Code Breakdown

1. ZodiacSignPredictor — the class (lines 1–19)

zodiac_sign_predictor.py

class ZodiacSignPredictor:
    def __init__(self):
        self.signs = [
            (1, 20, 'Aquarius'), (2, 19, 'Pisces'), (3, 21, 'Aries'), (4, 20, 'Taurus'),
            (5, 21, 'Gemini'), (6, 21, 'Cancer'), (7, 23, 'Leo'), (8, 23, 'Virgo'),
            (9, 23, 'Libra'), (10, 23, 'Scorpio'), (11, 22, 'Sagittarius'), (12, 22, 'Capricorn')
        ]
 
    def predict(self, month, day):
        for m, d, sign in self.signs:
            if (month == m and day >= d) or (month == m % 12 + 1 and day < self.signs[m % 12][1]):
                print(f"Zodiac sign: {sign}")
                return sign
        print("Invalid date.")
        return None
 
    def demo(self):
        self.predict(3, 25)
        self.predict(7, 30)
