### 注释 ###

'''
    多行注释
    '''
    """
    多行注释
    """

### 输出 ###

'''
    def print(
        *values: object, sep: str | None = " ", end: str | None = "\n", file: _SupportsWriteAndFlush[str] | None = None, flush: bool
    ) -> None: ...
    '''
    print("Hello world!","你好世界", sep=";", end="...")

### 变量 ###

'''
    1. 见名知义
    2. 下划线分割法：多个单词组成的名称，使用小写字母，单词与单词之间使用下划线分开
    3. 大驼峰命名法： 多个单词组成的名称，每个单词的首字母大写，其余小写
    4. 小驼峰命名法： 多个单词组成的名称，第一个单词的首字母小写，其余单词的首字母大写
    '''
    
    # 变量名 = 值
    a = 1
    b = 2
    # 保存和
    c = a + b
    print(c)
    
    # 数值类型
    # 整数
    num = -5
    # 检测数据类型的方法
    print(type(num))
    # float类型
    num2 = 3.14
    print(type(num2))
    # 布尔型,首字母必须大写
    bool = True
    print(type(bool))
    # complex 复数型，a是实部，b是虚部，j是虚部单位 c = a + bj
    c = 1 + 2j
    print(type(c))
    
    # 字符串
    # 特点：单引号，双引号都行，包含了多行内容的时候可以使用三引号
    str = 'hello world'
    
    # 格式化输出
    # % 占位符
    name = '张三'
    print('你好，%s' % name)
    # %d 整数
    age = 18
    print("我的名字是%s,今年%d岁" % (name, age))
    # %4d 整数，占4位空白
    print("%4d" % age)
    # %04d 整数，占4位，左边用0填充
    print("%04d" % age)
    # %.4f 浮点数
    a = 3.1415926
    print("%f" % a) # 默认保留小数点后6位，四舍五入
    print("%.4f" % a)
    # %%
    print("我是%%的1%%" % ())
    print("我是%")
    
    # f格式化，f{表达式}
    print(f"我是{
          name}，今年{
          age}岁")
