Kode Python. Python in Visual Studio Code Working with Python in Visual Studio Code using the Microsoft Python extension is simple fun and productive The extension makes VS Code an excellent Python editor and works on any operating system with a variety of Python interpreters It leverages all of VS Code&#39s power to provide auto complete and IntelliSense linting debugging and unit testing along with the ability to easily switch between Python environments including virtual and conda environments Software Version 163.

Python is a generalpurpose versatile and popular programming language It’s great as a first language because it is concise and easy to read and it is also a good language to have in any programmer’s stack as it can be used for everything from web development to software development and scientific applications.

Getting The List of Links from A WebsiteGetting The Resolution of An ImageRotating ImagesResizing ImagesSearching For A FileGetting The Day of The Week from A DateGenerating A Random PasswordConclusionIn this first code example you&#39re going to build a command line tool to gather all links presented on a given website page For that you&#39re going to obtain the HTMLcode from the website and look for patterns that represent links in this code To obtain the HTML code from a website you&#39ll need to perform an HTTP request Python&#39sstandard library has some alternatives to perform HTTP requests but most of them are not that easy to use Fortunately there&#39s Requests a library that implements “HTTP for humans” as said in its documentation page As it is not part of Python&#39s standard library you&#39re going to have to install it using pip by running the following command To implement a command line tool that is useful in daytoday life you&#39ll have to consider some aspects such as input validation and the use of command line arguments However before going into these details it&#39s important to begin with the simplest implementation possible as shown next Here you&#39re using request In this example you&#39re going to build a command line tool to obtain the resolution of an image For that you are going to use the Pillow library which allows you to perform several tasks related to image processing As Pillow is not part of Python&#39s standard library you&#39ll have to install it using pip by running the following command After the installation finishes you can start developing a simple version of the tool with the following code Just like in the previous example this first implementation is meant to be the simplest one without input validation or the use of command line arguments Here you&#39re importing the Image module from Pillow Note that the library is named PIL for compatibility reasons with a previous library that was discontinued In the sequel you obtain a file name from user input and open the image using Imageopen() Finally you use the size()method to obtain the resolution of the image and output a friendly message with this information Try sa In this example you&#39re going to use Pillow again this time to build a command line tool to perform rotation of images So before you begin make sure you have installed Pillow by running pip install pillow Like you did in the previous examples start with a simple implementation by running the following code As you can see this code is very similar to the one used in the beginning of the previous example Nevertheless besides getting the image file name you also get the rotation angle interactively from user input As input() returns strings you need to convert angleto float in order to be able to use it with Pillow to perform the image rotation Next you open the image like the previous example and then perform a rotation using the rotate() method saving the result to the im_rotateobject Finally you save the result stored in im_rotate as a new image with a file named as the original name prefixed by rotated_ Try saving the code as rotate_imagepy and then run i In this example you&#39ll complete your image manipulation toolset by implementing a resizing tool For that you are going to use Pillow again So make sure you have installed it by running pip install pillow Besides that you&#39re going to use the techniques presented in the previous examples So make sure you go through them to get details about the implementation before trying this example As usual you&#39ll start with a simple implementation just to see how Pillow is used to perform image resizing For that consider the following code If you compare this code to the one used in the beginning of the previous example you&#39ll notice they are very similar The main differences are the following 1 Here you are considering three arguments image width and height 2 Since width and height should be integer values you convert them using int() 3 To perform the resize of the image you use the method resize() which receives a tuple to define the new dimension in the form (width In this example you&#39ll build a file searching tool using the Pathlib module As a simple implementation you can use the following code You begin by importing Path from pathlib module Then you get the file name to search from user input You also get the folder in which the search will be performed In this case the default value “”is considered when the user input is empty which represents the current folder Finally you use the rglob() method to search for a file name pattern in the folder specified by folder As rglob() returns a list of path objects to print all occurrences you iterate on the list using a for loop For each item of the list the absolute path is obtained using the absolute()method and printed as output Try saving the program as find_filepyand perform a search Note that you can use wildcards when inputting the file name The output should be like the following Now add input validation and support for command line arguments with the following code In this example you&#39re going to build a command line tool to return the day of the week given a date For that you&#39re going to use the Datetime module which is in Python&#39sstandard library As usual begin with a simple implementation with the following code In this example you use datetimedate to perform the processing and obtain the day of the week for a given date This way you begin by importing it with from datetime import date Next you get a date from the user in the format mm/dd/yyyy and perform some string manipulations to separate the integer numbers for the month day and year With these numbers you instantiate a date object named date_date With the date object date_date all you need to do to get the day of the week is to call the weekday() method It returns an integer from 0 to 6 where 0 represents Monday and 6 represents Sunday which is stored in the variable n_day_of_week To convert this result to the actual name of the day you define a tuple of stri In this final example you&#39ll build a random password generator The program will take the desired password length and whether or not to use digits or special characters in the password It will output a random sequence of characters to be used as a password To understand the main logic of the program consider the simple implementation shown next In this program after importing the libraries you are getting three inputs from user 1 Whether or not to use digits in the password stored in the binary variable use_digits which defaults to True in case the user leaves this answer blank 2 Whether or not to use special characters in the password stored in the binary variable use_punctuation which defaults to True in case the user leaves this answer blank 3 The length of the password stored in the variable password_length which defaults 10 in case the user leaves this answer blank Then a list of possible symbols named symbolsis constructed based on the information prov In this article you&#39ve gone through the implementation of python code examples as command line tools for everyday use You&#39ve seen Argparse is very handy to implement several kinds of command line tools It allows you to build them with nice help messages and can also perform validation for the arguments Now that you&#39ve learned the basics of implementing them go ahead and improve your collection by implementing some other useful tools!
