我使用Python 2.7.13在我的Windows 7 64位中安装了Anaconda.

我通过在anaconda安装目录中找到python.exe来在我的Python中设置解释器.

我可以运行程序.但是,我无法使用Pycharm的软件包安装程序安装其他软件包.

我看过在线指南,但到目前为止没有任何帮助.我究竟做错了什么？

编辑:我使用管理器存储库按钮添加了链接https://pypi.python.org/simple.

但是,它不起作用

我试图从这个输入链接描述中提取所有那些类名称适合正则表达式模式frag-0-0,frag-1-0等的标签

我正在尝试以下代码

driver = webdriver.PhantomJS()
    for frg in frgs:
        driver.get(URL + frg[1:])
        frags=driver.find_elements_by_xpath("//*[starts-with(@id, 'frag-') and ends-with(@id, '-0')]")
    for frag in frags:
            for tag in frag.find_elements_by_css_selector('[class^=fragmark]'):
                lst.append([tag.get_attribute('class'), tag.text])
    driver.quit()

这是我的追溯:

我在Python2.7中执行以下操作:

>>> a = [1,2,3,4,5]
>>> b = [2,1,3,4]
>>> c = [3,4]
>>> map(None, a, b, c)
[(1, 2, 3), (2, 1, 4), (3, 3, None), (4, 4, None), (5, None, None)]

我试图在Python3中做类似的事情

>>> a = [1,2,3,4,5]
>>> b = [2,1,3,4]
>>> c = [3,4]
>>> map(None, a, b, c)
<map object at 0xb72289ec>
>>> for i,j,k in map(None, a, b, c):
...  print (i,j,k)
...

我正在尝试对梵文词进行音节化

धर्मक्षेत्रे - >धर्मक्षेत्रेdharmakeshetre - > DHAR麦SHET重

wd.split('?')

我得到的结果如下:

['??', '??', '???', '??']

哪个部分正确

我尝试另一个词कुरुक्षेत्र - >कुरुक्षेत्रेkurukshetre - >区鲁格她唱到tre

['?????', '???', '??']

结果显然是错误的.

如何有效地提取音节？

我想使用 Outlook 发送电子邮件。代码如下：

import smtplib
from email.message import EmailMessage

msg = EmailMessage()
msg['From'] = '*******'
msg['Subject'] = 'Some subject here'
msg['To'] = '********'
        
msg.set_content('Some text here')

with smtplib.SMTP_SSL('smtp-mail.outlook.com', 587) as smtp:
    smtp.login('******', '****')
    smtp.send_message(msg)
    print('Email sent!')

我收到以下错误：

我正在尝试运行使用selenium模块的python代码.这段代码在我的PC中使用了一个chromedriver完美运行.我试图在c9.io中运行它.我下载了chromedriver 64位版本,并使用chmod授予777权限.我仍然无法让它发挥作用

但是,我收到以下错误:

任何人都可以告诉我如何解决这个问题

我有一个countif函数,使用它我想要计算那些在任何地方都有数字字符的单元格.

Column A
Rich-Dilg-street 3
I have 4 apples
I have seven dogs

如何countif使用通配符编写标准,以便我可以计算具有数字字符的标准？在上面的例子中,答案应该是2(1和2不是3)

我想在用户未登录时将他们重定向到登录页面。

这是我的代码：

我正在尝试从 watchseriesfree.to 网站上的特定文件主机中提取一些链接。在以下情况下，我想要rapidvideo 链接，所以我使用regex 过滤掉那些带有包含rapidvideo 的文本的标签

import re
import urllib2
from bs4 import BeautifulSoup

def gethtml(link):
    req = urllib2.Request(link, headers={'User-Agent': "Magic Browser"})
    con = urllib2.urlopen(req)
    html = con.read()
    return html


def findLatest():
    url = "https://watchseriesfree.to/serie/Madam-Secretary"
    head = "https://watchseriesfree.to"

    soup = BeautifulSoup(gethtml(url), 'html.parser')
    latep = soup.find("a", title=re.compile('Latest Episode'))

    soup = BeautifulSoup(gethtml(head + latep['href']), 'html.parser')
    firstVod = soup.findAll("tr",text=re.compile('rapidvideo'))

    return firstVod

print(findLatest())

但是，上面的代码返回一个空白列表。我究竟做错了什么？

这是我的json:

[
{"name": "John Smith","date":"2017-02-02T23:07:09Z","id":"1223234"}
{"name": "John Doe","date":"2015-07-03T21:05:10Z","id":"3242342"},
{"name": "Jane Fan","date":"2016-12-22T13:27:19Z","id":"2123444"}
]

我已将上面的内容转换为hashmap.现在我想对日期值进行排序.

是否有内置功能可以帮助我实现这一目标？例如,用Python排序
