In the process of using Python, my favorite is the various third-party libraries of Python, which can complete many operations.
Here are 22 projects built with Python to learn Python programming.
You can also construct your own solutions according to the purpose and prompts of the project to improve the level of programming.
① Dice Simulator
Purpose: Create a program to simulate rolling dice.
Tip: When the user asks, use the random module to generate a number between 1 and 6.
② rock-paper-scissors game
Goal: Create a command line game where players can choose between rock, scissors and cloth, and PK with the computer. If the player wins, the score will be added until the end of the game, and the final score will be shown to the player.
Tip: Accept the player's choice and compare it with the computer's choice. The computer's selection is randomly selected from the selection list. If the player wins, 1 point is added.
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)
③Random password generator
Goal: Create a program that can specify the length of the password to generate a string of random passwords.
Tip: Create a string of numbers + uppercase letters + lowercase letters + special characters. A string of passwords is randomly generated according to the set password length.
④Sentence generator
Purpose: Generate a random and unique sentence through the input provided by the user.
Tip: Take the nouns, pronouns, adjectives, etc. entered by the user as input, then add all the data to the sentence and combine them to return.
⑤ guessing game
Purpose: In this game, the task is to create a script that can generate a random number in a range. If the user guesses the number correctly in three chances, then the user wins the game, otherwise the user loses.
Tip: Generate a random number, and then use the loop to give the user three guesses, and print the final result according to the user's guess.
⑥Story generator
Purpose: Every time the user runs the program, a random story will be generated.
Tip: The random module can be used to select random parts of the story, the content comes from each list.

email['to'] = 'xyz id' ## Whom we are sending
email['subject'] = 'xyz subject' ## Subject of email
email.set_content("Xyz content of email") ## content of email
with smtlib.SMTP(host='smtp.gmail.com',port=587)as smtp:
## sending request to server
smtp.ehlo() ## server object
smtp.starttls() ## used to send data between server and client
smtp.login("email_id","Password") ## login id and password of gmail
smtp.send_message(email) ## Sending email
print("email send") ## Printing success message
⑨ Abbreviations

Tip: You can get the first word by splitting and indexing, and then combine them.
⑩Word adventure game
Purpose: To write an interesting Python script that allows users to have interesting adventures by choosing different options for the path.
⑪ Hangman
Purpose: Create a simple command line hangman game.
Tip: Create a list of passwords and choose a word at random. Now each word is represented by an underscore "_" to provide the user with an opportunity to guess the word. If the user guesses the word correctly, replace the "_" with the word.
import time
import random
name = input("What is your name? ")
print ("Hello, " + name, "Time to play hangman!")
time.sleep(1)
print ("Start guessing...\n")
time.sleep(0.5)
## A List Of Secret Words
words = ['python','programming','treasure','creative','medium','horror']
word = random.choice(words)
guesses = ''
turns = 5
while turns > 0:
failed = 0
for char in word:
