A Guide to Getting Started with Python from Scratch
Python is a simple, easy-to-use and powerful programming language that is very suitable for beginners to get started. This article will provide you with a Python coding guide from scratch, help you understand the basics of Python, and provide specific code examples to help you get started quickly.
print("Hello, World!")
Save these codes as a file with a .py suffix, such as hello.py. Then, run the file via the command line and you will see the output "Hello, World!" on the console.
# 整数 num1 = 10 # 浮点数 num2 = 3.14 # 字符串 name = "John" # 布尔值 is_true = True is_false = False
# 算术运算符 a = 10 b = 5 print(a + b) # 加法 print(a - b) # 减法 print(a * b) # 乘法 print(a / b) # 除法 print(a % b) # 取模运算 print(a ** b) # 幂运算 # 比较运算符 x = 10 y = 5 print(x > y) # 大于 print(x < y) # 小于 print(x == y) # 等于 print(x != y) # 不等于 # 逻辑运算符 p = True q = False print(p and q) # 逻辑与 print(p or q) # 逻辑或 print(not p) # 逻辑非
age = 18 if age >= 18: print("你已经成年了!") else: print("你还未成年!")
# for循环 numbers = [1, 2, 3, 4, 5] for number in numbers: print(number) # while循环 count = 0 while count < 5: print(count) count += 1
def add_numbers(a, b): sum = a + b return sum result = add_numbers(5, 10) print(result)
Now, you know the basics of Python and have some code examples. Through continuous practice and practice, you can further master Python and use it to develop more interesting and practical applications. I wish you all the best in your Python programming journey!
