Python
Python is a dynamically typed programming language designed by Guido van Rossum. Much like the programming language Ruby, Python was designed to be easily read by programmers. Because of its large following and many libraries, Python can be implemented and used to do anything from webpages to scientific research.

A description is incomplete. It should mention:
These patterns are not competing, but complementing each other. To achieve availability, one needs both fail-over and replication.

"There are two main patterns to support high availability: fail-over and replication. "

There are some interesting algorithms in simulation from Physics, Chemistry, and Engineering especially regarding Monte Carlo simulation: Heat Bath algorithm, Metro-Police algorithm, Markov Chain Monte Carlo, etc.
Huge and nice collection and also getting very much appreciated from the community.
It would be great if somebody can translate into English then it will be reaching out to global.
I pulled the latest version of flask Flask from the master branch, commit 64ba43411fbfb2e435455b0df2453d7809b7c5a8.
The Quickstart minimal example on the dev version of Flask does not run as intended. Previous versions of the Quickstart example would display a simple "Hello world" message, but the addition of an undefined "name" variable causes the example to fail with a NameError.

Steps:
- Go to a nonexistent page in Keras docs, e.g. https://keras.io/asdfsada so the 404 page is shown
- Search something
- You are redirected to https://search.html/?q=something instead of a relative URL
It's not clear from the website's documentation, or the --help output, how to do the following equivalent curl task:
Post a raw JSON query to ElasticSearch:
curl \
--header "Content-Type: application/json" \
--request POST \
--data '{ "_source": [ "restricted_countries.*" ], "query": { "match_all": {} }, "size": 1000 }' \
'http://localhost:9200/_search'

We're trying to fix as many broken links as possible before modules move into collections. This is the batch of broken links on some Ansible modules.
NOTE: the link checker sometimes reports an error where a link actually works. Ignore those if you find them.
ISSUE TYPE
- Documentation Report
COMPONENT NAME
When using the url http://docs.python-requests.org/en/latest/, it redirects to https://2.python-requests.org//en/latest/ (notice the extra / before en). This causes a HTTP 404.
Expected Result
The redirect should be to https://2.python-requests.org/en/latest/
Actual Result
HTTP 404
Reproduction Steps
Try to visit the latest en documentation for requests using the
Similar to https://github.com/pytorch/pytorch/pull/34037/files we can view a complex tensor as a float tensor and pass it to uniform_ used by rand

Is there a way Tensorflow git cloned repositories can run without overhead issues?
After removing the Python 2.7 support, this section:
https://docs.scrapy.org/en/latest/topics/leaks.html#debugging-memory-leaks-with-guppy
should be removed or merged with this:

The chat tutorial listed for elixir is outdated. It uses a old version of phoenix and could be confusing to new users who would be learning a oudated set of syntax, application structure, commands i.e. mix phoenix.create vs. mix phx.create.
Also it's missing some steps. For one this they never do mix ecto.create without which the postgres database is not initialized so the app doesn't wo
使用队列实现栈的下列操作:
push(x) -- 元素 x 入栈
pop() -- 移除栈顶元素
top() -- 获取栈顶元素
empty() -- 返回栈是否为空
注意:
你只能使用队列的基本操作-- 也就是 push to back, peek/pop from front, size, 和 is empty 这些操作是合法的。
你所使用的语言也许不支持队列。 你可以使用 list 或者 deque(双端队列)来模拟一个队列 , 只要是标准的队列操作即可。
你可以假设所有操作都是有效的(例如, 对一个空的栈不会调用 pop 或者 top 操作)。

Similar to certbot/certbot#7803, it seems like ideally our code should pass mypy's tests regardless of the Python version it is run on, but we currently specify that Python 2.7 should be used. Can we make our tests pass everywhere and stop pinning this?
I think listing anti-patterns with some basic reasoning about "why not" is a good idea.
Example - singleton. Although #256 has "won't fix" label
- it is in PRs section, and people (if searching history at all) are searching issues first.
- it was misspelled, Singelton instead of Singleton, therefore impossible to find
Listing most popular anti-patterns (without actual implementation) shou

For what I see, when a build in the CI for a commit to master fails, only the user who triggered the action receives an alert (assuming the user has notifications enabled in their settings).
I think for Travis and pipelines, some people are receiving notifications for all the failures. Ideally we would like to be

I was having a very hard time figuring out
fill = A.stack().mean()
A.add(B, fill_value=fill)fill = 4.5. However I computed a value of 3.2 because I was taking the mean from the column of A not the DataFrame A.
This coming after the Indexing chapter where "explicit is better than implicit." I was thinking that this should be a little more explicit.

tf.functionmakes invalid assumptions about arguments that areMappinginstances. In general, there are no requirements forMappinginstances to have constructors that accept[(key, value)]initializers, as assumed here.This leads to cryptic exceptions when used with perfectly valid
