带你用Python制作7个程序，让你感受到端午节的快乐

在Python中，我们可以用不同的方式来制作程序，以下是一些例子：

1. 用Python制作一个简单的计算器：

# 用Python制作一个简单的计算器
 
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):
    if y==0:
        return "Cannot Divided by Zero"
    else: 
        return x / y
 
print("Select operation.")
print("1.Add")
print("2.Subtract")
print("3.Multiply")
print("4.Divide")
 
# 用户输入选择
choice = input("Enter choice(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))
else:
    print("Invalid input")

2. 用Python制作一个简单的随机密码生成器：

# 用Python制作一个简单的随机密码生成器
 
import string
import random
 
def generate_password(length=8):
    password_characters = string.ascii_letters + string.digits + string.punctuation
    return ''.join(random.choice(password_characters) for _ in range(length))
 
print(generate_password())

3. 用Python制作一个简单的图片压缩工具：

# 用Python制作一个简单的图片压缩工具
 
from PIL import Image
 
def image_compress(img_path, to_size):
    img = Image.open(img_path)
    img.thumbnail(to_size)
    img.save(img_path, "JPEG")
 
image_compress('test.jpg', (500, 500))

4. 用Python制作一个简单的文本转语音工具：

# 用Python制作一个简单的文本转语音工具
 
import pyttsx3
 
def text_to_speech(text):
    engine = pyttsx3.init()
    engine.say(text)
    engine.runAndWait()
 
text_to_speech('Hello, World!')

5. 用Python制作一个简单的天气预报应用：

# 用Python制作一个简单的天气预报应用
 
import requests
 
def get_weather(city):
    api_key = 'YOUR_API_KEY'
    url = 'http://api.openweathermap.org/data/2.5/weather?appid=' + api_key + '&q=' + city
    response = requests.get(url)
    weather = response.json()
    temp = weather['main']['temp']
    return temp
 
print("Temperature in " + city + ": " + str(get_weather(city)) + " degree Celsius")
