Text Data In Python Cheat Sheet
Welcome to our cheat sheet for working with text data in Python! We've compiled a list of the most useful functions and packages for cleaning, processing, and analyzing text data in Python, along with clear examples and explanations, so you'll have everything you need to know about working with text data in Python all in one place.Python Sets and Set Theory Tutorial
Learn about Python sets: what they are, how to create them, when to use them, built-in functions and their relationship to set theory operations.Pandas Tutorial: DataFrames in Python
Explore data analysis with Python. Pandas DataFrames make manipulating your data easy, from selecting or replacing columns and indices to reshaping your data.See MoreSee MorePada tutorial kali ini, kita akan mencoba membuat beberapa grafik dari data distribusi normal. Dalam Machine Learning, data dapat mencapai angka ribuan, atau bahkan jutaan.
Buka command prompt. Sebelum memulai, terlebih dahulu kita harus meng-install package matplotlib yang berfungsi untuk membuat grafik, dengan perintah sebagai berikut,
pip install matplotlibMisalnya kita ingin membuat scatter plot menggunakan 1000 data yang berdistribusi normal secara random. Pada array pertama memiliki mean 5.0 dengan standar deviasi 1.0, sedangkan pada array kedua akan memiliki mean 10.0 dengan standar deviasi 2.0. Kita dapat menggunakan perintah berikut,
import numpyimport matplotlib.pyplot as plt
x = numpy.random.normal(5.0, 1.0, 1000)
y = numpy.random.normal(10.0, 2.0, 1000)
plt.scatter(x, y)
plt.show()
Salin script di atas dan letakkan pada notepad, lalu save dengan nama scatter.py dan misalnya di simpan dalam folder c://coba.
Untuk melihat grafik scatterplot yang akan dihasilkan, gunakan perintah berikut,
c:/coba>python scatter.pyMaka akan muncul hasil scatter plot seperti gambar berikut
Selanjutnya, kita akan mencoba membuat grafik histogram dengan perintah seperti berikut,
import numpyimport matplotlib.pyplot as pltx = numpy.random.normal(5.0, 1.0, 1000)plt.hist(x, 100)
plt.show()
Salin pada notepad, misalkan kita simpan pada folder yang sama seperti tadi yaitu c://coba dengan nama hist.py. Setelah itu, dapat kita panggil grafik histogram dari data random dengan perintah seperti berikut,
Did you know that you can visualize your datasets using Python? 📊 Make your datasets simpler to understand and analyze by visualizing them. By creating a beautiful and easy-to-read data visualization you can convey insightful information about the dataset. 👀 Matplotlib is an open-source graph plotting library in Python that allows you to create different types of graphs using your own data values to visualize your data in your preferred way. 🧑💻 Have you used Python before?

Web accessibility is all about being considerate. Keep in mind those who have physical difficulties with accessing web content! 🫶 The one thing you should never forget when working with web development is to make your web pages accessible. Making your web page accessible will help you assure a good user experience for all users, independent of their custom device settings, or disabilities. 💚 Use semantic elements to give your elements meaning, there are approximately 110 elements in HTML 5, of which only two elements have no built-in accessibility features. When working with web development, you should always check for the best suitable semantic elements for your content! ⚡️ Take consideration of your design, the contrast and size of your elements, and most importantly functionality. Make sure that every user will find a way to comfortably use your web page without any unnecessary confusion. 🧩 Learn more about the diversity of abilities and how to make your web pages suitable for all kinds of users! ✨ //lnkd.in/ePhUHA2a Have you or anyone you know had any difficulties using various web pages? Share your past experiences in the comments below! 👀 #w3schools #development #education #accessibility #programming #learning #webdevelopment #technology #code

Have you ever had one of those days where you feel super powerful after debugging someone else code? 😎 Debugging is the process of finding and fixing errors in your code. An essential skill for any programmer, as it allows you to identify problems with your code and find ways to fix them.🚀 Also, debugging is about poking and working with the code until you find the issue. And debugging other people's code is the ultimate test of patience and problem-solving skills.⚡️ It can be a time–consuming and frustrating process, but it is an essential part of the software development cycle. With practice, you will become more skilled at finding and fixing errors in your code.🎉 Spending hours working on someone else's code trying to track down a pesky bug can take some time. But nothing is quite like the feeling of satisfaction and accomplishment when you finally solve the bug. ⏰ Have you ever had an experience with debugging others' code?

Got a project idea for a new website? Discover the differences between static and dynamic websites and find the best fit for your project! 🔍 Do you want to work with implementing beautiful front-end designs without doing any backend development? In that case, creating a static website is the perfect choice for your project. Static websites can have exciting functionalities, by using JavaScript you can make the website interactive and connect APIs to enhance the user experience. ✨ If your project requires an integrated database where you can store, edit and fetch data from, a dynamic website is a right choice! Dynamic websites are websites that have a backend environment within them, which can be used by the user to either input, edit, or request data through the front end of the website. 🧩 Your choice depends on what you expect the user to do on your website, if you want the user to simply have the access to your content, you might not need it to be any more advanced than a static website. ⚡️ If you would rather give the user more possibilities within the website, such as the ability to register and log in, or the ability to add their own content to your website in a simple and quick way, you should choose to create a dynamic website for your project! 🧑💻 Get started by creating a website in W3Schools Spaces and stay tuned for our upcoming release for Dynamic Spaces! 👀 #w3schools #website #static #dynamic #frontend #webdevelopment #programming #backend #fullstack #project #learning
