10个适合入门学习的python小程序_python解决学习和生活中实际问题的小程序

Python是一种广泛使用的编程语言，它简单易学，适合初学者入门。在这篇文章中，我将分享10个适合入门学习的Python小程序，希望帮助初学者更好地掌握这门语言。

1. 打印 Hello World:

   print("Hello, World!")
   1

2. 计算器：

   num1 = float(input("Enter first number: "))
   num2 = float(input("Enter second number: "))
   result = num1 + num2
   print("Sum:", result)
   1
   2
   3
   4

3. 猜数字游戏：

   import random
   
   target_number = random.randint(1, 100)
   guess = int(input("Guess the number between 1 and 100: "))
   
   if guess == target_number:
       print("Congratulations! You guessed the correct number.")
   else:
       print("Sorry, the correct number was:", target_number)
   1
   2
   3
   4
   5
   6
   7
   8
   9

4. 字符串反转：

   original_string = input("Enter a string: ")
   reversed_string = original_string[::-1]
   print("Reversed string:", reversed_string)
   1
   2
   3

5. 温度转换：

   temperature_celsius = float(input("Enter temperature in Celsius: "))
   temperature_fahrenheit = (temperature_celsius * 9/5) + 32
   print("Temperature in Fahrenheit:", temperature_fahrenheit)
   1
   2
   3

6. 列表操作：

   my_list = [1, 2, 3, 4, 5]
   doubled_list = [x * 2 for x in my_list]
   print("Original list:", my_list)
   print("Doubled list:", doubled_list)
   1
   2
   3
   4

7. 求解二次方程：

   import math
   
   a = float(input("Enter the coefficient a: "))
   b = float(input("Enter the coefficient b: "))
   c = float(input("Enter the coefficient c: "))
   
   discriminant = b**2 - 4*a*c
   
   if discriminant > 0:
       x1 = (-b + math.sqrt(discriminant)) / (2*a)
       x2 = (-b - math.sqrt(discriminant)) / (2*a)
       print("Roots are real and different. x1 =", x1, "x2 =", x2)
   elif discriminant == 0:
       x = -b / (2*a)
       print("Roots are real and the same. x =", x)
   else:
       real_part = -b / (2*a)
       imaginary_part = math.sqrt(abs(discriminant)) / (2*a)
       print("Roots are complex. x1 =", real_part, "+", imaginary_part, "i, x2 =", real_part, "-", imaginary_part, "i")
   1

   14
   15
   16
   17
   18
   19

8. 文件读写：

   with open("example.txt", "w") as file:
       file.write("Hello, this is an example.")
   
   with open("example.txt", "r") as file:
       content = file.read()
       print("File content:", content)
   1
   2
   3

9. 简单的类和对象：

   class Dog:
       def __init__(self, name, age):
           self.name = name
           self.age = age
   
       def bark(self):
           print("Woof!")
   
   my_dog = Dog("Buddy", 3)
   print("My dog's name is", my_dog.name, "and age is", my_dog.age)
   my_dog.bark()

10. 基本的异常处理：

    try:
        num1 = int(input("Enter a number: "))
        num2 = int(input("Enter another number: "))
        result = num1 / num2
        print("Result:", result)
    except ValueError:
        print("Please enter valid numbers.")
    except ZeroDivisionError:
        print("Cannot divide by zero.")
    except Exception as e:
        print("An error occurred:", e)
    1
