我正在尝试安装最新版本的六个python包,但我有以下问题.在mac OSX 10.10.2中无法摆脱六个1.4.1
sudo pip install six --upgrade
Requirement already up-to-date: six in /Library/Python/2.7/site-packages
Cleaning up...
pip search six
six - Python 2 and 3 compatibility utilities
INSTALLED: 1.9.0 (latest)
python -c "import six; print six.version"
1.4.1
which -a python
/usr/bin/python
which -a pip
/usr/local/bin/pip
这有什么不对？不能升级六个!
我有一个弹性搜索文档,格式如下.我需要部分更新"x"字段并在其中添加python dict.
{
"_index": "gdata34",
"_type": "gdat",
"_id": "328091-72341-118",
"_version": 1,
"_score": 1,
"_source": {
"d": {
"Thursday": {
"s": ""
},
"Email": {
"s": ""
},
"Country": {
"s": "US"
},
},
"x": {
"Geo": {
"s": "45.335428,-118.057133",
"g": [
-118.057133
,
45.335428
]
}
},
}
}
我尝试了以下代码来更新:
from elasticsearch import Elasticsearch, exceptions
import pprint
elasticsearch = Elasticsearch()
doc = elasticsearch.get(index='gdata34', doc_type='gdat', id='328091-72341-7')
elasticsearch.update(index='gdata34', doc_type='gdat', id='328091-72341-7',
body={"script":"ctx._source.x += y",
"params":{"y":"z"}
}
)
elasticsearch.indices.refresh(index='gdata34')
new_doc = elasticsearch.get(index='gdata34', doc_type='gdat', id='328091-72341-7') …我需要提取远程mp3文件的ID3标签和元数据.
我写了几行可以得到本地文件的ID3标签:
from mutagen.mp3 import MP3
import urllib2
audio = MP3("Whistle.mp3")
songtitle = audio["TIT2"]
artist = audio["TPE1"]
print "Title: " + str(songtitle)
print "Artist: "+str(artist)
我需要为mp3文件的url链接实现这一点.我试图使用urllib2部分下载文件.
import urllib2
from mutagen.mp3 import MP3
req = urllib2.Request('http://www.1songday.com/wp-content/uploads/2013/08/Lorde-Royals.mp3')
req.headers['Range'] = 'bytes=%s-%s' % (0, 100)
response = urllib2.urlopen(req)
headers = response.info()
print headers.type
print headers.maintype
data = response.read()
print len(data)
如何在不完全下载文件的情况下提取MP3网址的ID3标签？
我修改了我的仪表板并尝试将其保存为主页,我收到以下消息
主页设置此页面已设置为默认的Kibana仪表板
我仍然无法将修改后的仪表板作为默认仪表板加载,请告诉我如何操作.
我正在尝试在 elasticsearch 中获取索引（不是商店）的实际大小。我使用了索引 API 来获取统计信息。
GET doc/_stats
“索引”-“index_total”是实际索引大小吗？
"total": {
"docs": {
"count": 1000000,
"deleted": 0
},
"store": {
"size_in_bytes": 118078896
},
"indexing": {
"index_total": 1000000,
"index_time_in_millis": 30985,
"index_current": 0,
"index_failed": 0,
"delete_total": 0,
"delete_time_in_millis": 0,
"delete_current": 0,
"noop_update_total": 0,
"is_throttled": false,
"throttle_time_in_millis": 0
},
我试图将从richeditDocument生成的内存流转换为字节数组.代码如下:
Public Sub saveAsTemplate_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Dim ms As MemoryStream = New MemoryStream()
richEditControl1.SaveDocument(ms, DocumentFormat.Rtf)
GetStreamAsByteArray(ms)
MessageBox.Show("save")
End Sub
Private Function GetStreamAsByteArray(ByVal stream As MemoryStream) As Byte()
Dim streamLength As Integer = Convert.ToInt32(stream.Length)
Dim fileData As Byte() = New Byte(streamLength) {}
' Read the file into a byte array
stream.Read(fileData, 0, streamLength)
stream.Flush()
stream.Close()
Return fileData
End Function
生成流时我可以获得流长度,但最终的咬合数组只包含0,使其无效.我怎样才能获得正确的字节数组？
我有一个带有英文文本和标点符号的阿拉伯字符串.我需要过滤阿拉伯语文本,我尝试使用sting删除标点符号和英语单词.但是,我丢失了阿拉伯语单词之间的间距.我哪里错了？
import string
exclude = set(string.punctuation)
main_text = "????? ????????: ?? ????? ????? ??????? ????? ?? ??????? ??????? ?? ????? http://alriyadh.com/1031499"
main_text = ''.join(ch for ch in main_text if ch not in exclude)
[output after this step="????? ???????? ?? ????? ????? ??????? ????? ?? ??????? ??????? ?? ????? httpalriyadhcom1031499]"
n = filter(lambda x: x not in string.printable, n)
print n
????????????????????????????????????????????????????????????
我能够删除标点符号和英文文本,但我丢失了单词之间的空格.我怎样才能保留每一个字？
我正在使用python Beautiful汤来获取以下内容：
<div class="path">
<a href="#"> abc</a>
<a href="#"> def</a>
<a href="#"> ghi</a>
</div>
我的代码如下：
html_doc="""<div class="path">
<a href="#"> abc</a>
<a href="#"> def</a>
<a href="#"> ghi</a>
</div>"""
from bs4 import BeautifulSoup
soup = BeautifulSoup(html_doc)
path = soup.find('div',attrs={'class':'path'})
breadcrum = path.findAll(text=True)
print breadcrum
输出如下，
[u'\n', u'abc', u'\n', u'def', u'\n', u'ghi',u'\n']
如何只以这种形式获取结果：abc,def,ghi作为单个字符串？
我也想知道这样获得的输出。
我需要根据从侧边栏中选择的输入更改mydb(字符串)值.
library(shiny)
shinyUI(fluidPage(
titlePanel("Shiny App"),
sidebarLayout(
sidebarPanel( selectInput("site",
label = "Choose a site for Analysis",
choices = c("abc", "def",
"ghi", "jkl"),
selected = "abc")
),
mainPanel(
textOutput("text"),
)
))
library(shiny)
library(ggplot2)
library(RMySQL)
shinyServer(function(input, output) {
if(input$site=="abc"){
mydb<-"testdb_abc"}
else if(input$site=="def"){
mydb<-"testdb_def"}
con <- dbConnect(MySQL(),dbname=mydb, user="root", host="127.0.0.1", password="root")
query <- function(...) dbGetQuery(con, ...)
output$text <- renderText({
paste("You have selected:",input$site)
})
})
在上面的server.R中,我需要根据选定的输入为mydb分配字符串值.我收到此错误:
Error in .getReactiveEnvironment()$currentContext() :
