Five Beginner Python Projects: Rock‑Paper‑Scissors Game, Random Password Generator, Dice Simulator, Email Sender, and Alarm Clock

Python’s extensive third‑party libraries make it easy to build useful utilities quickly. Below are five small projects that illustrate core concepts such as user input handling, randomization, email communication, and time‑based scheduling.

1. Rock‑Paper‑Scissors Game

Goal: Create a command‑line game where the player chooses rock, paper, or scissors, competes against a computer‑selected move, and accumulates points until the player exits.

Tip: Use random.choice to pick the computer’s move and compare it with the player’s input.

import random
choices = ["Rock", "Paper", "Scissors"]
computer = random.choice(choices)
player = False
cpu_score = 0
player_score = 0
while True:
    player = input("Rock, Paper or  Scissors?").capitalize()
    # 判断游戏者和电脑的选择
    if player == computer:
        print("Tie!")
    elif player == "Rock":
        if computer == "Paper":
            print("You lose!", computer, "covers", player)
            cpu_score += 1
        else:
            print("You win!", player, "smashes", computer)
            player_score += 1
    elif player == "Paper":
        if computer == "Scissors":
            print("You lose!", computer, "cut", player)
            cpu_score += 1
        else:
            print("You win!", player, "covers", computer)
            player_score += 1
    elif player == "Scissors":
        if computer == "Rock":
            print("You lose...", computer, "smashes", player)
            cpu_score += 1
        else:
            print("You win!", player, "cut", computer)
            player_score += 1
    elif player == 'E':
        print("Final Scores:")
        print(f"CPU:{cpu_score}")
        print(f"Plaer:{player_score}")
        break
    else:
        print("That's not a valid play. Check your spelling!")
    computer = random.choice(choices)

2. Random Password Generator

Goal: Generate a password of user‑specified length containing digits, uppercase and lowercase letters, and special characters.

Tip: Build a character pool string and use random.sample to pick unique characters.

import random
passlen = int(input("enter the length of password"))
s = " abcdefghijklmnopqrstuvwxyz01234567890ABCDEFGHIJKL MNOPQRSTUVIXYZ!aN$x*6*( )?"
p = ".join(random.sample(s, passlen))
print(p)
# Example interaction
# enter the length of password
# 6
# Za1gB0

3. Dice Simulator

Goal: Simulate rolling a six‑sided die on user request.

Tip: Use random.randint(1,6) inside a loop that continues while the user inputs 1.

import random
while int(input('Press 1 to roll the dice or 0 to exit:\n')):
    print(random.randint(1, 6))
# Example output
# Press 1 to roll the dice or 0 to exit:
# 1
# 4

4. Automatic Email Sender

Goal: Write a script that sends an email using Python’s email and smtplib libraries.

Tip: Create an EmailMessage object, fill the headers and content, then connect to an SMTP server with TLS.

import smtplib
from email.message import EmailMessage
email = EmailMessage()
email['from'] = 'xyz name'
email['to'] = 'xyz id'
email['subject'] = 'xyz subject'
email.set_content("Xyz content of email")
with smtplib.SMTP(host='smtp.gmail.com', port=587) as smtp:
    smtp.ehlo()
    smtp.starttls()
    smtp.login("email_id", "Password")
    smtp.send_message(email)
print("email send")

5. Simple Alarm Clock

Goal: Create a Python script that triggers an alarm at a specified time.

Tip: Parse the user‑provided HH:MM:SS time, compare it with the current time in a loop, and play a sound using playsound when they match.

from datetime import datetime
from playsound import playsound
alarm_time = input("Enter the time of alarm to be set:HH:MM:SS\n")
alarm_hour = alarm_time[0:2]
alarm_minute = alarm_time[3:5]
alarm_seconds = alarm_time[6:8]
alarm_period = alarm_time[9:11].upper()
print("Setting up alarm..")
while True:
    now = datetime.now()
    current_hour = now.strftime("%I")
    current_minute = now.strftime("%M")
    current_seconds = now.strftime("%S")
    current_period = now.strftime("%p")
    if alarm_period == current_period:
        if alarm_hour == current_hour:
            if alarm_minute == current_minute:
                if alarm_seconds == current_seconds:
                    print("Wake Up!")
                    playsound('audio.mp3')
                    break

These examples demonstrate how Python can be leveraged for quick prototyping of games, utilities, and automation scripts, making it an ideal language for beginners to practice core programming concepts.
