end5 ="s"

end6 ="e"

end7 ="B"

end8 ="u"

end9 ="r"

end10 ="g"

end11 ="e"

end12 ="r"

 # watch that comma at the end.  try removing it to see what happens

print(end1 +end2 +end3 +end4 +end5 +end6, end=' ' )

print(end7 +end8 +end9 +end10 +end11 +end12)

知识点分析：

一 .format 的用法

与{}一起使用，目的解决字符串变量的插入

二、在print（）输出语句中出现 end=‘ ’的语句，是什么意思呢？

简单来说，如果没有end=‘ ’，每次print语句都会自动换行，而有了这个语句，数据就不会自动换行，而是在输出的数据后面加上空格（空格数取决于引号里面的空格数）。
