问题很白，真是不好意思。
What I want to do is to read the input.txt file line by line and then put
into a function and write the output line by line to output.txt.
with open('/path/to/directory/input.txt','r') as f:
with open('/path/to/directory/output.txt','w') as g:
for x in f:
x = x.rstrip()
if not x: continue
print >> g, some_lib.some_function(x)
But sometimes the function won't be able to generate the output for x, and
report error. I tried to use exception handling in Python, but the program
loops over the first line instead of moving on to the next line.
with open('/path/to/directory/input.txt','r') as f:
with open('/path/to/directory/GeoIP/output.txt','w') as g:
for x in f:
x = x.rstrip()
if not x: continue
while True:
try:
print >> g, some_lib.some_function(x)
except ValueError:
print >> g, "cannot find value"
请问我哪里搞错了？不好意思我是文科的。。。

In general, all antihypertensive medications require prescription.
But there are lots of medications that only cost $4 for a month's supply
once you have prescriptions, much cheaper than those in China.

太谢谢了！
我把while true干掉以后就可以了。
但是出现exception的时候好像程序直接跳过print >> g, "cannot find value"，没有
写入错误信息怎么办？
with open('/path/to/directory/input.txt','r') as f:
with open('/path/to/directory/GeoIP/output.txt','w') as g:
for x in f:
x = x.rstrip()
if not x: continue
try:
print >> g, some_lib.some_function(x)
except ValueError:
print >> g, "cannot find value"
结果就是我有100个input，output文件只有50几个。。。，我希望output也有一百个，
只是有些是“cannot find value”
我把while true干掉以后就可以了。

报错是这样的：
File "GeoIPcity.py", line 10, in
print >> g, gi.cityby_name(x)
File "build/bdist.linux-i686/egg/pygeoip/__init__.py", line 551, in org_by
_name
File "build/bdist.linux-i686/egg/pygeoip/__init__.py", line 412, in _
gethostbyname
socket.gaierror: [Errno -5] No address associated with hostname
这个是不是ValueError啊？其他的我不知道了。。。请问还有可能是什么种类的
exception我可以一个一个套。用的是geoip的包。
太谢谢了！
