python语法之用户交互

#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
