我有一个问题,即将YAML文件中的文档映射到dict并正确映射它们.
我有以下YAML文件,它代表一个server(db.yml):
instanceId: i-aaaaaaaa
environment:us-east
serverId:someServer
awsHostname:ip-someip
serverName:somewebsite.com
ipAddr:192.168.0.1
roles:[webserver,php]
我加载这个YAML文件,我可以毫无问题地做,我想我明白了.
instanceId = getInstanceId()
stream = file('db.yml', 'r')
dict = yaml.load_all(stream)
for key in dict:
if key in dict == "instanceId":
print key, dict[key]
我希望逻辑像以下一样工作:
instanceId匹配的是getInstanceId(),则打印出该文档的所有键和值.如果我从命令行查看地图数据结构,我得到:
{'instanceId': 'i-aaaaaaaa environment:us-east serverId:someServer awsHostname:ip-someip serverName:someserver ipAddr:192.168.0.1 roles:[webserver,php]'}
我想我可能是不正确地为YAML文件创建数据结构,并且在匹配内容时dict,我有点迷失.
旁注:我无法加载此文件中的所有文件yaml.load(),我试过yaml.load_all(),这似乎有用,但我的主要问题仍然存在.
import argparse
parser = argparse.ArgumentParser(prog='tool')
args = [('-u', '--upf', 'ref. upf', dict(required='True')),
('-s', '--skew', 'ref. skew', {}),
('-m', '--model', 'ref. model', {})]
for args1, args2, desc, options in args:
parser.add_argument(args1, args2, help=desc, **options)
parser.print_help()
输出:
usage: capcheck [-h] -u UPF [-s SKEW] [-m MODEL]
optional arguments:
-h, --help show this help message and exit
-u UPF, --upf UPF ref. upf
-s SKEW, --skew SKEW ref. skew
-m MODEL, --model MODEL
ref. model
我如何打印参考.-m MODEL, --model MODEL当我使用-h …
我是 YAML 格式和 kubernetes 的新手。
下面是一个dep_prom.yml文件。

my_obj.short = "Hello"
my_obj.long = "Line1\nLine2\nLine3"
我希望YAML看起来像这样:
short: "Hello"
long: |
Line1
Line2
Line3
我怎样才能指示PyYAML这样做？如果我调用yaml.dump(my_obj)它,它会产生一个类似dict的输出:
{long: 'line1
line2
line3
', short: Hello}
(不确定为什么长的是这样的双倍间距...)
我可以指示PyYAML如何对待我的属性吗？我想影响顺序和风格.
是否可以在bitbucket管道中组合多个具有相同步骤的分支？
例如:我工作的团队使用两个名称之一作为他们的评论分支,"rev"或"staging".无论哪种方式,都使用相同的步骤发布到我们的审查服务器.现在,分支被单独调出.
pipelines:
branches:
rev:
steps:
- echo 'step'
staging:
steps:
- echo 'step'
但它可能是这样的
pipelines:
branches:
rev|staging:
steps:
- echo 'step'
如何格式化这样的YAML文档,以便PyYAML可以正确解析它？
Data: Some data, here and a special character like ':'
Another line of data on a separate line
我知道':'字符是特殊的所以我必须用引号括起整个东西:
Data: "Some data, here and a special character like ':'
Another line of data on a separate line"
为了添加新行,我必须添加'\n':
Data: "Some data, here and a special character like ':'\n
Another line of data on a separate line"
有没有格式化YAML文档,所以我不必添加\n's以便有一个新行？
我试图让ZSH配置在Mac OSX上正常工作.我用curl安装它:curl -L https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh | sh.然后我修改了我的zshrc文件以满足我的需求.它只在我跑完后才有效source ~/.zshrc.但是如果我回来打开新标签或新终端,我必须做的source ~/.zshrc是让配置设置再次运行.有人遇到过这个问题吗？我相信有一种方法可以做到这一点,所以我不需要为~/.zshrc每个新标签做源.

import yaml
foo = {
'name': 'foo',
'my_list': [{'foo': 'test', 'bar': 'test2'}, {'foo': 'test3', 'bar': 'test4'}],
'hello': 'world'

我怎样才能以my_list这种方式缩进元素？
