我从Instagram API获得以下数据,我试图property从caption使用以下代码获取文本:
data = simplejson.load(info) # info is retrieved using the urllib2
for post in data['data']:
if post['caption'] is not "null":
try:
post['caption']['text']
except NameError:
post['caption']['text'] = 0
if post['caption']['text'] is not 0:
print post['caption']['text']
但是在打印unicode字符串时我一直收到TypeError: 'NoneType' object has no attribute '__getitem__'错误+ UnicodeEncodeError: 'charmap' codec can't encode characters in position 0-5: cha
racter maps to <undefined>错误
以下是检索和存储的JSON数据 info

+5:30
如何使用Python从此UTC偏移量中获取时区缩写？
如
+5:30 => IST
甚至可以使用Python来做到这一点吗？
我有以下清单：
a = [100, 34, 2, 100]
我想要最大的索引值：
$ a.index(max(a))
Returns: 0
什么是在这种情况下获得的最后一个索引（具有最大值）的Python的方式3。
（因为最大值重复多次。）
就在一个小时前，我启动了tailingapache日志文件（访问日志），从那时起，我注意到这个奇怪的用户代理（无法在Google的官方文档中找到它）。
我对此感到怀疑，因为我在 Google 网站上找不到有关此用户代理的任何内容，
("Mozilla/5.0 (compatible; GoogleApps script; +http://script.google.com/bot.html))
它一整天、每分钟都在抓取我们网站的登录页面。
这是日志片段：
72.14.199.55 - - [07/Aug/2013:16:06:28 +0000] "GET / HTTP/1.1" 302 639 "-" "Mozilla/5.0 (compatible; GoogleApps script; +http://script.google.com/bot.html)"

而且一直是同一个IP。而现在仍然如此，
这种爬行模式常见吗？
我试图迭代一个字符串向量,并在字符串的每个字符上:
但我得到一个错误:C++禁止指针和整数之间的比较.
In member function ‘int LetterStrings::sum(std::vector<std::basic_string<char> >)’:
error: ISO C++ forbids comparison between pointer and integer [-fpermissive]|
以下是我的代码:
#include<iostream>
#include<vector>
#include<typeinfo>
#include<string>
using namespace std;
class LetterStrings {
public:
int sum(vector <string> s) {
int i, j = 0;
int count = 0;
for(i=0;i<s.size();i++) {
for(j=0;j<s[i].length();j++) {
if(s[i][j] != "-") {
count ++;
}
}
}
return count;
}
};
有人可以告诉我,我的代码有什么问题.
**我对C++很陌生.
