## Extracting Data from the HTTP Remaining API, Configuring the HTTP Request Header for Cookie Authentication

I need to extract data from the HTTP Web API. However, it requires a cookie authentication. I can retrieve the cookie information when I look at the Chrome browser. However, I do not know how to configure headers and authentication type in Azure Data Factory V2. Can you please give us some details? (I successfully extracted the data for token-based authentication, but cookie one, I do not know how.)

## python – loop for extracting JSON from data frames and storing in a new data frame

I have a data frame (derived from a CSV file stored by MySQL) with multiple columns, one of which consists of a string representing the representation of a JSON. The data looks like this:

``````id   email_id     provider  raw_data       ts
1    aa@gmail.com    A      {'a':'A',   2019-23-08 00:00:00
'b':'B',
'c':'C',
``````

And what is my desired issue:

``````email_id      a   b   c
aa@gmail.com  A   B   C
``````

What I have coded so far is this:

``````import pandas as pd
import ast

df1 = pd.DataFrame()

for i in range(len(df)):
dict_1 = ast.literal_eval(df('raw_content')(i))
df1 = df1.append(pd.Series(dict_1),ignore_index=True)

pd.concat((df('email_id'),df1))
``````

This works, but has a very big problem: it's extremely low (it takes hours for 100,000 rows). How could I speed up this process?

## Complexity of the calculation of \$ f ^ {(n)} (0) \$ / Extracting a coefficient of a function series

Many combinatorial problems can be solved using generation functions.

In such a case, we get a function $$f (x)$$that (usually) has a Taylor expansion:
$$f (x) = sum_ {n ge 0} a_n x ^ n$$
Thus the coefficients $$a_n$$ are exactly the elements of the sequence we are looking for.

Furthermore, we can assume that the function $$f (x)$$ is given in closed form, d. H. as a finite function constructed using only elementary functions.

Unlike the determination of Taylor expansion, we now want a single coefficient $$a_k$$fixed for some $$k$$,

What is the most efficient way to do this?

I've already asked the question on math.stackexchange, where I got an answer to which I am bound $$mathcal O (log_2 (n) ^ alpha)$$ is possible. However, I can not figure out from the answer how this limit is established.

## Extracting pairs in which the y component has a relative maximum value

I have a list of several couples. You can find it here or create it manually. Applies `ListPlot` on the list provided is the following representation:

How do I extract the maximum pairs? `(x,y)`, whose `y` Components are recognizable in the plot as a single list.

## Performance Optimization – Optimal method for extracting the "positive part" of a multivariate polynomial

I have multivariate polynomials with numerical coefficients like e. G.

``````p - s - p q^2 s^2 + 3 r s^2 + 3 r^2 s^2 - p r^2 s^2 - 2 q r^2 s^2 - 2 r^3 s^2 + s^3
``````

and I want to take the sum of these monomials only with positive coefficients.

Although for my purposes

``````FromCoefficientRules[Select[CoefficientRules[poly],Last[#]>0&],Variables[poly]]
``````

It seems to be fast enough, it's about translating into another form and back, so I think there's a better way to do that, probably using some tricks on the internal representation of polynomials.

Is there?

## Plotting – Extracting points from a 3D plot that lie along a random line

``````seedRandom[5]
d = RandomReal[1, {100, 3}];
``````

You can use `-5 + 3 # - # 2 &` (or `function[{x, y}, -.5 + 3 x - y]`) as a setting for `MeshFunctions` in the `ListPlot3D`:

``````show[lp3d = ListPlot3D[d, MeshFunctions -> {-.5 + 3 # - #2 &},
Mesh -> {{0}}, MeshStyle -> Directive[Red, Thick], BoundaryStyle -> None].
Graphics3D[{Thick , Blue, Line[{{0, -.5, 1}, {0.5, 1, 1}}].
opacity[.5, Yellow], EdgeForm @ None,
InfinitePlane[{{0, -.5, 0}, {0, -.5, 1}, {0.5, 1, 1}}]}]]
``````

To extract the points on the red line:

``````cases[Normal @ lp3d, Line[x_] :> x, all][[1]]
``````

## infopath – Extracting data from the manifest.xsf file with PowerShell

Hi, I'm trying to extract information about the rules that are applied to a number of InfoPath forms and use Powershell for that.

I unpacked that `template.xsn` File and found the `manifest.xsf` File that stores this data.

Use the PowerShell `[xml]\$ ProjectXmlFile = Get-Content manifest.xsf` In order to get the XML data, I have problems correctly identifying the nodes.

The nodes are labeled with the "`xsf:`"Precursor, for example:

``````
The form can not be sent due to an error.

``````

How do I identify these nodes to output the information as normal XML data (that is, if the node was not prefixed with "xsf:")?

I tried to use that:

``````foreach (\$ DataQuery in \$ ProjectXmlFile. # xsf: xDocumentClass # 39; xsf: dataObjects # 39; xsf: dataObject # 39; xsf: query & # 39; xsf: sharepointListAdapterRW & # 39;
{
Write-Host "DataQuery.name = \$ (\$ DataQuery. # Xsf: name #)"
}
``````

Or is there another reason why I can not access these nodes?

## Speech Discussion – Python Extracting specific data from a large file

Background information to this code before I ask this question. I'm trying to write a code that extracts certain data from a very large text file (over 900,000 lines). Batch ID = Q19176, Wafer ID = 19, Chip X Coordinate = 11, Chip Y Coordinate = 53

I'm just looking for that information to be printed out in the format "Q19176_19_11_53" above. There are a few thousand lines containing the LOT IDs, Wafer IDs, and the x and y coordinates. The numbers vary every time. I need help with what the code would look like.

## Design Pattern – Should I pass \$ element while extracting functions or return HTML + callback function?

I can not think of a clean way to create this pattern, which has been in my javascript for years and amounts to adding HTML and a related event listener.

The first pattern looks cleaner, but has a logical effect on the results of my reading about functional programming.

``````Function first (\$ el) {
\$ el.html (& # 39;``````& # 39);
\$ el.find (& # 39; asdf & # 39;). on (& # 39; something & # 39 ;, () => {});
}

first (\$ (& # 39; body & # 39;));
``````

The second pattern looks very ugly, so I'm really not a fan of it.

``````Function second () {
let html = & # 39;``````& # 39 ;;
let callback = function (\$ el) {\$ el.find (& # 39; asdf & # 39;). on (& # 39; something & # 39 ;, () => {});}
return [html, callback]
}

let asdf = second ();
let \$ el = \$ (& # 39; body & # 39;);
\$ el.html (asdf[0]);
asdf[1](\$ el);
``````

Is there a pattern for doing this without making it ugly?
