这是我拥有的大型 csv 文件的一部分：

"66.35.223.128","66.35.223.143","1109647232","1109647247","AU","Australia"
"66.35.223.144","66.35.227.191","1109647248","1109648319","US","United States"
"66.35.227.192","66.35.227.207","1109648320","1109648335","JP","Japan"
"66.35.227.208","66.35.230.31","1109648336","1109648927","US","United States"
"66.35.230.32","66.35.230.47","1109648928","1109648943","AU","Australia"
"66.35.230.48","66.35.236.207","1109648944","1109650639","US","United States"
"66.35.236.208","66.35.236.223","1109650640","1109650655","AU","Australia"
"66.35.236.224","66.36.127.255","1109650656","1109688319","US","United States"

前两列是 IP 地址范围。我有一个 IP 地址 66.35.250.168 我需要搜索 csv 文件以查看它位于哪个范围内，并打印出相应的国家/地区名称。

由于前两个数字 (66,35) 是相同的，我打算搜索包含它的行。我可以通过这样做搜索一个完整的字符串（66.35.205.88）：

import csv
with open('GeoIPCountryWhois.csv', mode='r') as f:
    reader = csv.reader(f)
    for row in reader:
        if row[0] in ['66.35.205.88']:
            print row

如果我搜索 66.35，我不会得到任何结果。你能告诉我一种我可以搜索字符串的一部分的方法吗（这里是'66.35'）？另外，您能告诉我如何找到找到字符串的确切行号吗？

提前致谢。
