有趣的python程序

以下是一些有趣的Python程序:

1. 猜数字游戏:

import random

secret_number = random.randint(1, 100)
guess = 0
tries = 0

print("Welcome to the Guess That Number game!")
print("I'm thinking of a number between 1 and 100.")
print("You have 10 tries to guess it.\n")

while guess != secret_number and tries < 10:
    guess = int(input("Enter your guess: "))
    if guess < secret_number:
        print("Too low.")
    elif guess > secret_number:
        print("Too high.")

    tries += 1

if guess == secret_number:
    print("\nCongratulations! You guessed my number in", tries, "tries!")
else:
    print("\nSorry, you failed to guess my number. It was", secret_number)

2. 计算器程序:

def add(x, y):
    return x + y

def subtract(x, y):
    return x - y

def multiply(x, y):
    return x * y

def divide(x, y):
    return x / y

print("Select operation.")
print("1. Add")
print("2. Subtract")
print("3. Multiply")
print("4. Divide")

while True:
    choice = input("Enter choice (1/2/3/4): ")

    if choice in ('1', '2', '3', '4'):
        num1 = float(input("Enter first number: "))
        num2 = float(input("Enter second number: "))

        if choice == '1':
            print(num1, "+", num2, "=", add(num1, num2))

        elif choice == '2':
            print(num1, "-", num2, "=", subtract(num1, num2))

        elif choice == '3':
            print(num1, "*", num2, "=", multiply(num1, num2))

        elif choice == '4':
            print(num1, "/", num2, "=", divide(num1, num2))
        break
    else:
        print("Invalid Input")

3. 矩阵乘法程序:

def matrix_multiplication(X, Y):
    result = []
    for i in range(len(X)):
        row = []
        for j in range(len(Y[0])):
            sum = 0
            for k in range(len(Y)):
                sum += X[i][k] * Y[k][j]
            row.append(sum)
        result.append(row)
    return result

X = [[1, 2, 3],
     [4, 5, 6],
     [7, 8, 9]]

Y = [[10, 11, 12],
     [13, 14, 15],
     [16, 17, 18]]

result = matrix_multiplication(X, Y)

for row in result:
    print(row)

4. 无限制斐波那契数列生成器:

a, b = 0, 1
while True:
    yield a
    a, b = b, a + b

5. 简单的爬虫程序:

import requests
import re

url = 'https://www.wikipedia.org/'
response = requests.get(url)

if response.status_code == 200:
    pattern = re.compile('<title>(.*?)</title>')
    title = re.search(pattern, response.text)
    print(title.group(1))
else:
    print("Error:" + response.status_code)

这些程序可以帮助你理解Python语言的特点和功能。如果你对Python编程感兴趣，可以继续学习并编写更复杂的程序。
