给出以下单元格中定义的雇员列表,处理字典列表以创建格式为标题姓氏的雇员姓名列表,例如乔纳森·卡尔德隆先生等
到目前为止,我可以打印出标题,仅此而已...
我的工作:
htaccess
输出:
htaccess
词典列表:
RewriteCond %{HTTP_HOST} ^(www\.)(.*) [NC]
RewriteRule (.*) https://%2%{REQUEST_URI} [R=301,L]
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [R=301,L]
预期输出:
new_list2 = list(map(lambda x: x["title"], employees))
print(new_list2)
答案 0 :(得分:3)
您可以使用列表推导,并使用operator.itemgetter
从每个字典中获取感兴趣的值:
from operator import itemgetter
l = ['title', 'firstname', 'lastname']
[' '.join(itemgetter(*l)(i)) for i in employees]
输出
['Mr Jonathan Calderon', 'Mr Christopher Hansen', 'Mrs Isabella Dorsey', 'Ms Barbara Baker']
或者,如果您愿意使用map
:
[' '.join(map(lambda x: i.get(x), l)) for i in employees]
# ['Mr Jonathan Calderon', 'Mr Christopher Hansen', 'Mrs Isabella Dorsey', 'Ms Barbara Baker']

自从OP请求 $dir = $_SERVER['DOCUMENT_ROOT'] . '/images/products/';
$imgData = base64_decode(preg_replace('#^data:image/\w+;base64,#i', '', $this->input->post('croppedData')));
$characters = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';
$charactersLength = strlen($characters);
$randomString = '';
for ($i = 0; $i < 10; $i++) {
$randomString .= $characters[rand(0, $charactersLength - 1)];
}
$randomString .= ".jpg";
file_put_contents($dir . $randomString, $imgData);
以来,先生,这里是使用它且仅使用它的解决方案(不需要导入其他库):
map()
