我正在尝试安装upstox,这是一个用于连接市场数据的Python API.我无法在Python3.5上安装它.
我的配置是
Python 3.5.3 (v3.5.3:1880cb95a742, Jan 16 2017, 15:51:26) [MSC v.1900 32 bit (Intel)] on win32.而我一直得到的错误是:

Complete output from command python setup.py egg_info:

NSDataReadingOptions
Options for methods used to read NSData objects.
enum {
NSDataReadingMappedIfSafe = 1UL << 0,
NSDataReadingUncached = 1UL << 1,
NSDataReadingMappedAlways = 1UL << 3,
};
typedef NSUInteger NSDataReadingOptions;
它说
NSDataReadingUncached一个提示,指示该文件不应存储在文件系统缓存中.对于一次读取和丢弃的数据,此选项可以提高性能.适用于OS X v10.6及更高版本.在NSData.h中声明.
所以我假设默认情况下这些URL请求被缓存,如果我想使用共享全局缓存,则不需要实现NSURLRequest来缓存数据？这种理解是否正确？
我正在使用Google IOS SDK并已实施
- (UIView *)mapView:(GMSMapView *)mapView markerInfoWindow:(GMSMarker *)marker
实现自定义视图.当我显示此视图时,它不会添加标注,因为Google地图视图通常会为其自己的标记添加.任何人都可以让我知道如何添加这个标注像指针指向这个自定义makerInfoWindow的标记？
我是Python和dateutil模块的新手.我传递了以下论点:
disclosure_start_date = resultsDict['fd_disclosure_start_date']
disclosure_end_date = datetime.datetime.now()
disclosure_dates = [dt for dt in rrule(MONTHLY, dtstart=disclosure_start_date, until=disclosure_end_date)]
这里 disclosure_start_date = 2012-10-31 00:00:00转换为datetime是datetime.datetime(2012, 10, 31, 0, 0)
截止日期截至目前.
我用的时候:
disclosure_dates = [dt for dt in rrule(MONTHLY, dtstart=disclosure_start_date, until=disclosure_end_date)]
我得到每隔一个月或相隔2个月的日期.结果是:
>>> list(disclosure_dates)
[datetime.datetime(2012, 10, 31, 0, 0),
datetime.datetime(2012, 12, 31, 0, 0),
datetime.datetime(2013, 1, 31, 0, 0),
datetime.datetime(2013, 3, 31, 0, 0),
datetime.datetime(2013, 5, 31, 0, 0),
datetime.datetime(2013, 7, 31, 0, 0),
datetime.datetime(2013, 8, 31, 0, 0),
datetime.datetime(2013, 10, …我在表单的 HTML 中有链接
<a href="/downloadsServlet?docid=abc" target="_blank">Report 1</a>
<a href="/downloadsServlet?docid=ixyz" target="_blank">Fetch Report 2 </a>
我可以使用 BeautifulSoup 获取上述表单的链接列表
我的代码如下
from bs4 import BeautifulSoup
html_page = urllib2.urlopen(url)
soup = BeautifulSoup(html_page)
listOfLinks = list(soup.findall('a'))
但是，我想在引用链接的文本中找到包含“Fetch”一词的链接。
我试过表格
soup.findAll('a', re.compile(".*Fetch.*"))
但这行不通。如何仅选择具有 href 且文本部分中包含“Fetch”一词的标签 a？
