day3----输出之格式化输出

格式化输出

  • 1、%s、%d

    %s:可以接收任意类型的变量

    %d:只能接收数字类型

    按照传递顺序,传值

  • 2.  .format

  • 3.-string     #python3.6以后才有的特性

  • #格式: my name is Nick, my age is 18.          %s的使用方法
    name = input('请输入姓名:')
    age = input('请输入年龄:')
    print('my name is %s, my age is %s.'%(name, age)) 

     

  • print("He is %d years old."%(18))  # %d 打印整数
    print("His height is  %f m."%(1.85))   # %f 打印浮点数
    print("His height is  %.2f m."%(1.85))   # %.2f 打印浮点数保留2位小数
    print("Name:%10s Age:%4d Height:%6.2f"%("Nick", 18, 1.85))  # 指定占位符宽度
    print("Name:%-10s Age:%-4d Height:%-6.2f"%("Nick", 18, 1.85))  # 指定占位符宽度(左对齐)
    print("my name is {},my age is {}.".format("Nick", 18))  #一一对应传值
    print("my name is {name},my age is {age}.".format(age=18, name="Nick"))  #根据参数传值
    
    name = "Nick"
    age = 18
    print(f"His name is {name},my age is {age}.")  #f-string
    print(F"my name is {name},my age is {age}.")   #F大写F也可以
