数据中每行含有的数据结构为:
">"+"序号名"+"空格"+"数字"+","+"空格"+"数字"
想用一段python程序,
将数据内数字大小在9.500到12.500之间的行保留,
将数据内数字小于9.500和大于12.500的行删除,
比如,上面的数据,
删除行内"数字"小于"9.500"的行,和行内"数字"大于"12.500"的行后,
剩下的数据为:
Ai15-2 9.531, 9.531
Ai15-3 9.531, 9.531
Ai15-4 9.531, 9.531
Ai15-5 9.531, 9.531
Ai15-6 9.531, 9.531
Ai15-11 9.706, 9.706
Ai15-12 10.804, 10.804
Ai15-13 10.248, 10.248
Ai15-14 10.248, 10.248
Ai15-15 10.248, 10.248
Ai15-18 10.452, 10.452
Ai15-19 10.452, 10.452

最好可以在原来的TXT文件内直接操作;
也可以将删除之后留下的数据存放在新的文件中。
