全称为separate意为 分开 隔开
用于print两个元素时自定义间隔符(默认为两个空格)
关键字参数sep是实现分隔符，比如多个参数输出时想要输出中间的分隔字符
print(1, 2, 3, sep = ',', end = '\r\n')print(1, 2, 3, sep = ' ', end = '\r\n')

结果输出如下：
1,2,31 2 3
print("file\n","abc","bcd","fff\n","poi")print("-------------")print("file\n","abc","bcd","fff\n","poi",sep='')print("-------------")print("file\n","abc","bcd","fff\n","poi",sep=' ')print("-------------")
其结果为：
file abc bcd fffpoi-------------fileabcbcdfffpoi-------------file abc bcd fffpoi-------------
