9) Colorama
When you use ProgressBar to print the log, why not add color to them! In fact, when there is a major error, it will be able to give you a quick reminder.
Colorama is easy to use. Just write it in your script and add it to the text you want to print:
Colorama-red) UUID
For me, there are only a few tools that are really needed in programming: hash, key-value pair stora
First import the related module

The shiny in R has a partial problem.
In the field of data science, R Studio is the best IDE, and even Microsoft's VS has to mimic a data sciences model, which shows that the model of the Editor + console + data panel + plot panel is the most suitable for the analysis.
Python is not easy to use Ide,spyder package management and console is not good, Anaconda just put the Spyder into a bag. Rodeo is closest to R Studio, but it doesn't work with Node's front-end ca
First, the questionThere was a problem that bothered me for a long time.I have the following data, the first column is the Hour + minute, the second column is the value:0000 1120001 1230002 122...0059 1230100 120...2359 156How can I draw this into a time sequence diagram of minute granularity? The horizontal axis that is drawn directly using the Ggplot function is a number, not a time.Second, the answerThe essence of the problem is actually to unify t

Regression Model performance evaluation series 1-QQ chart, regression model evaluation 1-qq(Erbqi) the QQ plot is the Quantile-Quantile diagram, that is, the Quantile-Quantile diagram. A simple understanding is to plot the values of the two same Quantile distributions into points (x, y; if the two distributions are very close, the vertex (x, y) will be distributed near the y = x straight line; otherwise, no; the prediction result of the regression model can be evaluated from the QQ plot.

9)Colorama
Since you have set a good progress bar for logs, why not make them colorful! You can also remind yourself when a serious error occurs.
Colorama is super easy to use. Just pop up your script and add any text you want to change the color:
10)Uuid
In my mind, we actually only need a few tools for programming: hashing, key/value storage, and the Globally unique Identifier universally unique ids, uuid ). Uuid is built into t
drop and you want T o Make sure everyone gets their own promo code or ID number?And if you ' re worried on running out of IDs, then fear not! The number of UUIDs you can generate are comparable to the number of atoms in the universe.import uuidprint uuid.uuid4()# e7bafa3d-274e-4b0a-b9cc-d898957b4b61
Well if you were a

R Language Data Analysis series nine--by Comaple.zhangIn this section, logical regression and R language implementations, logistic regression (lr,logisticregression) is actually a generalized regression model, according to the types of dependent variables and the distribution can be divided into the common multivariate linear regression model, and logistic regression, the logistic regression is that the dependent variable is discrete and the value range is { 0,1} Two classes, if the discrete var

Sometimes the bar heights represent counts of cases in the data set, and sometimes they represent values in the data set (with The bar chart height represents the frequency (count) in the dataset, and sometimes represents the values in the dataset, which should be kept firmly in mind, otherwise c
