# 1、接收用户输入
# name=input('请输入你的用户名： ') # name='egon'
# print(name)

# 2、格式化输出
# name=input('username>>> ')
# age=input('age>>> ')

# print('my name is xxx my age is xxx')
# print('my name is '+name+' my age is '+age)
# print('my name is %s my age is %s' %(name,age))

# %d只能接收数字
# print('my age is %d' %10)
# print('my age is %d' %'aaaa')
# print('my age is %d' %10.1)

# print('my age is %s' %'aaa')
# print('my age is %s' %10)
# print('my age is %s' %['a',1])
