海外TECH	DEV Community	Code review best practices	https://dev.to/mnosov622/code-review-3l14	Code review best practicesHi everyone This week I ve been doing some code reviews for Telescope project I would love to share some tips for code review that I figured out I ve reviewed PRs PR and PR Don t take it personallyPeople review the code not your personality Project maintainers might be very strict Hence they might request changes for almost every line if they see it could be written better We have to remember that with code reviews we are just eliminating common mistakes and making ourselves better as developers Follow code review checklistList at least things you need to check in the code For example it could be the following Security Reusability e g can we reuse the written functions Code simplicity Multiple reviewersCode review is a team work meaning it s better when multiple people review a little piece of code It will help to stay focused and not feel overwhelmed As a beginner If you review only lines of code it will be much easier comparing to reviewing lines of code where at some point you might lose concentration Programmers are humans not robots Leave proper commentsIn the comments leave clear and concise comments about what should be changed and why it s a best practice Automate code stylingWe need to use automation for repetitive tasks as much as we can Use prettier and linter to make sure that code is easy to read If you enjoy blogs you could buy me a coffee It will motivate to write better blogs What else do you think could be considered as code review best practice Let me know in the comments	2022-11-19 20:49:43
海外TECH	DEV Community	NumPy Arrays	https://dev.to/tanveershahriar/numpy-arrays-3pmo	NumPy ArraysNumPy is a Python library used for working with arrays It also has functions for working in domain of linear algebra fourier transform and matrices NumPy was created in by Travis Oliphant It is an open source project and you can use it freely This module is mainly used for Data Science and Machine Learning InstallationWe can install NumPy using pip pip is a python package manager Go to your terminal and type pip install numpy Using NumPyTo use the built in function from NumPy we have to import it first import numpyBut after that if we want to use any function we have to write numpy every time to use that That s why it is convention to import numpy as np import numpy as np NumPy ArraysNumPy arrays essentially come in two flavors vectors and matrices Vectors are strictly d arrays and matrices are d but you should note a matrix can still have only one row or one column Creating Numpy ArraysWe can create an array by directly converting a list or list of lists There are also some built in functions to generate arrays arangenumpy arange start stop step arange is like the range function of python It returns evenly spaced values within a given interval Here start and step is optional if we need it but stop is mandatory arange can be called with a varying number of positional arguments arange stop Values are generated within the half open interval stop in other words the interval including start but excluding stop arange start stop Values are generated within the half open interval start stop arange start stop step Values are generated within the half open interval start stop with spacing between values given by step zerosnumpy zeros shape dtype float It generates a array of given shape and type filled with zeroes Here shape can be a int which will generate D array or a tuple of ints which will generate matrices Instead of tuple we can use list of ints also And dtype is by default float but we can change it into int onesnumpy ones shape dtype float It is same as the zeros function but instead of zeroes all of the elements are one linspacenumpy linspace start stop num Returns num evenly spaced samples calculated over the interval start stop And num is by default eyenumpy eye n Return a D array with ones on the diagonal and zeros elsewhere Simply it generates a nxn identity matrix RandomNumPy also has lots of ways to create arrays with random numbers randnumpy random rand d d dn Create an array of the given shape and populate it with random samples from a uniform distribution over randnnumpy random randn d d dn Return a sample or samples from the standard normal distribution Unlike rand which is uniform Also rand cannot generate negative values but randn can randintrandom randint low high None size None Return random integers from low inclusive to high exclusive If we don t mention size then it will return one value For size we can pass an int or a tuple of ints or a list of ints Array Attributes and Methods reshapeReturns an array containing the same data with a new shape But we have to declare the shape such that we have the proper amount of elements Suppose we have a array of elements We can transform it into a x matrix but we can not reshape into a x matrix as it can not contain element maxIt will return the max value of the array argmaxIt will return the index of the max value of the array minIt will return the min value of the array argminIt will return the index of the min value of the array ShapeShape is an attribute that arrays have which returns the shape of the array dtypeYou can also grab the data type of the object in the array That s it for today Feel free to ask any question in the comment	2022-11-19 20:26:32
