QUESTION
I've installed beautifulsoup (file named bs4) into my pythonproject folder which is the same folder as the python file I am running. The .py file contains the following code, and for input I am using this URL to a simple page with 1 link which the code is supposed to retrieve.
URL used as url input: http://data.pr4e.org/page1.htm
.py code:

Answered 2022-Jan-12 at 06:53Are you using python 3.10? Looks like beautifulsoup library is using removed deprecated aliases to Collections Abstract Base Classes. More info here: https://docs.python.org/3/whatsnew/3.10.html#removed
A quick fix is to paste these 2 lines just below your imports:

Is it possible to make a Beautifulsoup Strainer that strains all 'order-cards' from 'container-01' only (without 'order-cards' from other containers)? Below the sample HTML

I’m new to Go and to practice I do some coding exercice on Exercism. I stubbled on a particular exercice in which I’m having a hard time undestanding the solution. Here’s the code:
...ANSWER
Answered 2021-Mar-12 at 17:16The Keep method takes a function as a parameter. It expects it to be func (int) bool - a function taking an int and returning a bool.
When Keep is invoked in Discard, the code passes it an anonymous function with the right signature (take int, return bool). This anonymous function invokes strainer (which is a function passed into Discard) and returns its response, negated.
The idea is that strainer is a filter function: it tells you which elements to keep. So the implementation of Keep is straightforward: iterate over all elements, and keep only those for which strainer returns true.
Discard is written in a clever way using Keep, instead of also writing a loop like this:
QUESTION
I am currently trying to get live stock prices using the beautifulsoup and requests library from the yahoo finance website. I'm currently finding that the bottleneck for speed is that the request for the webpage takes around 0.5 seconds on average. Below is my code and output
...ANSWER
Answered 2020-Dec-15 at 07:39This seems a reasonable time for what you are doing (downloading and parsing a webpage).
In real I think that 0.4s should be enough for monitoring, but if you really need to have an higher update frequency (ie. you have got some new crazy trading algorithm) you can:
Try to parse a more lightweight page. (But you need to find one!)
Create a pool of thread performing many requests at the same time. You should note that this behaviour could lead to a violation of yahoo ToS and restrictions on your account/ip could be applied.
Use any sort of market API (free or payed) to avoid downloading an entire webpage and all its dependencies when you can just have something like a 20byte json (or similar) message. Also in this case you should read about the max pooling frequency you can use.
Use Selenium and perform just 1 connection to the webpage. When you detect any changes in the div you are interested in you get the updated value.

QUESTION
I'm currently in the process of migrating a Jekyll blog to a new theme and am now running into issues while pushing my site to GitHub pages and running the Jekyll site with the --safe flag.
Right now, the Jekyll site runs perfectly fine locally but I started hitting issues when pushing up to GitHub pages.
As a debugging measure, I read to ensure the Jekyll site runs without issues with the --safe flag which it does not.
However, I'm not exactly sure what the issue is here. Here's my output running it with bundle exec jekyll serve --safe --trace --verbose:
ANSWER
Answered 2020-Aug-26 at 17:29I finally got this working but I took a different approach rather than solving the --safe flag issue.
Instead, I now have two branches. One is for normal Jekyll development locally and the other is for pushing to GitHub pages (only the _site directory).
The entire process for that is outlined here.
QUESTION
My application returns a hash of keys and values and I'd like it to display them in an easily readable way. Is there a way I can get it to display the key's as well as the info. So if I search for a strain it will return something similar to this
ID: The ID number Name: The name Race: The race flavor: the flavor etc.
sample of what it prints:

Answered 2020-Aug-06 at 04:05There is a great console library called Hirb which can be used just for this purpose.
For example, assuming your array of hashes is in data, we can do this:

I have stored json format data in db, problem is it doesn't have quotes around it's values or properties.

You can then perform the next service logic for the vehicles.
QUESTION
I have a Word document where the user will input codes for standard comments, usually using an outline format like bullets 1, a, 2, and 3. The user saves and closes the Word document. Then the user can open a Comments Excel document and click on a button that will ask the user to find which Word document they want to replace the codes (column A) with the Text value (column C) in the Excel document. The code and process work great except when the value exceeds 255 characters, which will happen quite often. I've read about using the clipboard in doing this, but I wasn't sure how to implement it into my existing code. Thank you for any help. Sorry if I am not posting this correctly, new to this forum.
Sample comments in Word:
- B401
- B402
- M317
- This is my own comment
- P203
Sample in Excel file (each row separated by a comma):
- Column A rows- B401, B402, M317, P201, P203
- Column B rows- Handrail compliance, Handrail Extensions, HVAC, Water Building, Water System
- Column C rows- Handrails shall comply with section 1014 of the 2015 International Building Code., Handrails shall return to a wall guard or walking surface. (See Section 1014.6 of the 2015 International Building Code.), No HVAC drawings shown; will handle in the field., Where water pressure within a building exceeds 80 psi (552 kPa) static, an approved water pressure reducing valve conforming to ASSE 1003 or CSA B356 with strainer shall be installed to reduce the pressure in the building water distribution piping to 80 psi (552 kPa) static or less. Exceptions to this requirement are service lines to sill cocks and outside hydrants, and main supply risers where pressure from the mains is reduced to 80 psi (552 kPa) or less at individual fixtures. (See Section 604.8 of the 2015 International Plumbing Code.), A water test shall be applied to the drainage system either in its entirety or in sections. If applied to the entire system, all openings in the piping shall be tightly closed, except the highest opening, and the system shall be filled with water to point of overflow. If the system is tested in sections, each opening shall be tightly plugged except the highest openings of the section under test, and each section shall be filled with water, but no section shall be tested with less than a 10-foot (3048 mm) head of water. In testing successive sections, at least the upper 10 feet (3048 mm) of the next preceding section shall be tested so that no joint or pipe in the building, except the uppermost 10 feet (3048 mm) of the system, shall have been submitted to a test of less than a 10-foot (3048 mm) head of water. The water shall be kept in the system, or in the portion under test, for at least 15 minutes before inspection starts. The system shall then be tight at all points. (See Section 312.2 of the 2015 International plumbing Code.) Plastic piping shall not be tested with air. An air test shall be made by forcing air into the system until there is a uniform gauge pressure of 5 pounds per square inch (psi) (34.5 kPa) or sufficient to balance a 10-inch (254 mm) column of mercury. This pressure shall be held for a test period of at least 15 minutes. Any adjustments to the test pressure required because of changes in ambient temperature or the seating of gaskets shall be made prior to the beginning of the test period. (See Section 312.3 of the 2015 International Plumbing Code)

Answered 2020-Jan-27 at 20:45The fault is in the function you are using which can't accept a parameter of the size you want. So, we have to work around it a bit. Try replacing your for loop with this:
