1、首先打开JUPTER NOTEBOOK，新建一个空白的PY文档
3、print("first line", end = " ")print("second line", end = " ")print("third line", end = " ")如果用end，就可以定义为同一行，空格间隔
5、print("first line", end = "ABC")print("second line", end = "CCC")print("third line", end = "GWE")当然字符串间隔可以以字符串来定义
7、print("first line", end = ", ")print("second line", end = ", ")print("third line", end = ", ")如果用逗号来间隔，那么就看起来像列表一样
