可能重复:
重新索引数字数组键
我有一个数组如下
Array
(
[0] => 15/11/2012 - 18/11/2012
[1] => 15/11/2012 - 18/11/2012
[2] => 15/11/2012 - 18/11/2012
[3] => 15/11/2012 - 18/11/2012
[4] => 19/12/2012 - 24/12/2012
[5] => 24/12/2012 - 01/01/2013
[6] => 24/12/2012 - 01/01/2013
[7] => 16/01/2013 - 01/02/2013
)
我正在使用array_unique来删除给我的重复项
Array
(
[0] => 15/11/2012 - 18/11/2012
[4] => 19/12/2012 - 24/12/2012
[5] => 24/12/2012 - 01/01/2013
[7] => 16/01/2013 - 01/02/2013
)
如何更改密钥以使其连续 - 如下所示
Array
(
[0] => 15/11/2012 - 18/11/2012 …我有一个有两列的表 - artist,release_id
我可以运行什么查询来显示重复记录？
比如我的桌子是
ArtistX : 45677
ArtistY : 378798
ArtistX : 45677
ArtistZ : 123456
ArtistY : 888888
ArtistX : 2312
ArtistY: 378798
查询应显示
ArtistX : 45677
ArtistX : 45677
ArtistY : 378798
ArtistY : 378798
我有一个30个字符的字符串
我想只显示前10个,然后是......
所以例如
thisisastringthatis30characterslong
会成为
thisisastr ...
这可能使用CSS吗？
干杯!
我想知道是否insertion_date超过30天.这应该检测到当前时间的分钟和秒.值insertion_date将从API动态提取.
目前的代码只检测到一天,我需要精确到秒.
import datetime
import dateutil.parser
insertion_date = dateutil.parser.parse('2017-08-30 14:25:30')
right_now_30_days_ago = datetime.datetime.today() - datetime.timedelta(days=30)
print right_now_30_days_ago #2017-08-31 12:18:40.040594
print insertion_date #2017-08-30 14:25:30
if insertion_date > right_now_30_days_ago:
print "The insertion date is older than 30 days"
else:
print "The insertion date is not older than 30 days"

heroku config:add server=xxx.xxx.xxx.xxx

如何从 app.py 文件访问这些变量？
我尝试过以下方法但没有运气：
server = os.environ.get('server')
print server
exit()
运行时这不会向控制台返回任何有用的内容foreman start

/Users/siquick/Django/soundshelter/soundshelterapp/views.py in release(128)
genre = [release['genre'] for release in context_dict['release']]
views.py的代码段是:
release_list = Releases.objects.filter(id=release_id).values('all_artists','label_no_country','id','title','genre').annotate(cnt=Count('chartsextended'))[:1]
context_dict['release'] = release_list
genre = [release['genre'] for release in context_dict['release']]
label_no_country = [release['label_no_country'] for release in context_dict['release']]
all_artists = [release['all_artists'] for release in context_dict['release']]
title = [release['title'] for release in context_dict['release']]
造成这种重复的原因是什么？我知道它是由这条线造成的,genre = [release['genre'] for release in context_dict['release']]但不确定为什么会发生这种情况.
如何在表中找到第一个字符为数字的字符串？
我正在使用MySQL LIKE如下
SELECT DISTINCT label_no_country
FROM releases
WHERE label_no_country LIKE '$letter%'
ORDER BY label_no_country
$letterAZ之间的字母在哪里(取决于输入)
因此,如果$letter == 'A'那时它将显示第一个字母为A的所有条目.
如何运行此查询以便显示以数字开头的记录？
例如
1st record
