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.

def get_zodiac_sign(day, month):
    zodiac_dates = [
        (1, 20, 'Capricorn'), (2, 19, 'Aquarius'), (3, 21, 'Pisces'),
        (4, 20, 'Aries'), (5, 21, 'Taurus'), (6, 21, 'Gemini'),
        (7, 23, 'Cancer'), (8, 23, 'Leo'), (9, 23, 'Virgo'),
        (10, 23, 'Libra'), (11, 22, 'Scorpio'), (12, 22, 'Sagittarius'),
        (12, 31, 'Capricorn')
    ]
    for m, d, sign in zodiac_dates:
        if (month == m and day >= d) or (month == m+1 and day < zodiac_dates[m%12][1]):
            return sign
    return 'Unknown'

if __name__ == "__main__":
    main()
zodiac_sign_predictor.py
def main():
    print("Zodiac Sign Predictor")
    while True:
        cmd = input('> ')
        if cmd == 'predict':
            try:
                day = int(input("Day: "))
                month = int(input("Month: "))
                print(get_zodiac_sign(day, month))
            except Exception as e:
                print(f"Error: {e}")
        elif cmd == 'exit':
            break
        else:
            print("Unknown command. Type 'predict' or 'exit'.")
