How to use PyCharm
What an IDE is?
An Integrated Development Environment (IDE) software is used to build programs utilizing tools like an editor and compiler. This has a lot of potentials to be a helpful tool when programming in several languages.
It is a piece of software that combines all the functions and resources required by a programmer. It is graphical; therefore, to display information and receive user input, it uses windows and controls like buttons. Tools can be, for instance:
What is the need for an IDE?
Although utilizing an IDE is not strictly necessary, its extra functions are quite helpful. One of the most useful features an IDE can offer is code insight, which allows the software to understand what is typed. The software can alter the font color to represent various classes, functions, and variables. IntelliSense, a feature of Microsoft Visual Studios, can anticipate what you are typing and complete your sentences. Similar tools are available from other IDEs under names specific to those programs.
A further element of IDEs is the capacity for program debugging. This is unquestionably one of the most important resources for carrying out a successful program. Testing is essential to ensure that your user does not encounter an instance where the code fails to handle a particular problem and causes the software to crash. You can execute the program while debugging by stopping the code at specific moments to check the values of variables or other variables necessary to ensure the code and functions are working as planned.
The ability to compile your code and resource management are two more tools that IDEs can offer. It is crucial for the proper operation of the program that the files are in the proper locations since, when building a new program, multiple distinct files are frequently referenced in specific path locations. When using an IDE, it is simple to see a visual depiction of where these files are located, which helps the user comprehend it better.
Benefits of IDEs
Python is an extremely flexible language. Thousands of libraries and modules may be used with it. Python has gained a lot of traction among businesspeople and the broader industry since the majority of its libraries are available as open sources. And this unquestionably results in millions of content students around the world.

Additionally, programmers can use the editor to auto-generate code, expand a code block into an expression or logical block, access code snippets, format the code base, find typos and misspellings, and locate duplicate code. Additionally, the editor makes it simpler for developers to examine the code and spot issues as they are being written.
Programmers can update and improve code with PyCharm's intelligent code navigation features without spending additional time or effort. The IDE facilitates programmers' access to classes, files, symbols, and go-to declarations from references.
The user can instantly locate a specific item in the source code, a code snippet, a UI element, or a user activity. They can also set bookmarks in the code and find where specific symbols are used. The developers can even
use the code navigation feature to examine the code simultaneously in the lens mode.
Developers can more quickly and effectively apply both local and global changes by refactoring PyCharm. Even while creating simple Python code and using Python frameworks, developers can use the refactoring capabilities offered by the IDE. They can use rename and move to refactor for files, classes, functions, methods, properties, parameters, and local/global variables.
Likewise, removing variables, fields, constants, and parameters can raise the code's quality. Additionally, PyCharm's extract method enables programmers to split up lengthy classes and methods.
Widely used Web Technologies
Popular Python Web Frameworks are Supported.
Along with offering first-rate support for popular web technologies, PyCharm also offers first-rate support for a powerful Python web framework like Django. The IDE provides code completion suggestions for Django tags, filters, parameters, and template variables to the developers. In addition, users can use the short documentation to learn more details about tags and filters.
Even web developers can debug Django templates, format code, check code, and manage.py consoles with the Python IDE. In addition, PyCharm supports well-known Python web frameworks like Web2Py and Pyramid. It offers navigation options particular to the Pyramid as well as code completion.

Let's look at how to utilize PyCharm practically in the following post on this PyCharm Tutorial blog.
How do I use PyCharm?
Now that you know what it offers. Let's start with PyCharm, and I will show you the user interface.
Let's start by launching a brand-new project. When you first launch PyCharm, the following graphic appears to welcome you:
Looking here, on the left, you may see every recent project I've worked on. However, nothing will be in the left-hand column if this is your first time using PyCharm.
It is simple to start a new project by selecting the Create New Project tab and proceeding from there.
We use this image to configure our Python interpreter. However, this could be blank if Python is not installed on your system.
Use the official documentation to install Python, or follow the steps outlined below, to do so:
The following page will appear when you click on the tiny gear symbol to the right:
If you haven't installed Python individually, you can utilize the System Interpreter here. Do make sure the current Python installation version satisfies your requirements. Although I have several versions of Python installed, as you can see from the image above, I have been using Python 3.7.
After this, you create a blank file by clicking on - Scratch File -> Python File -> File -> File -> Create
When you're done, PyCharm will greet you with a blank screen and a file ready for you to code in.
The "hello world" program, the epitome of all coding, is typed out here.
However, you will need to include a correct configuration in the application if you need to run it.
How does PyCharm Add Configuration to a Project?
Look at the illustration below. This is the outcome of selecting Add Configuration from the screen for the scratch file.
Here, you are required to give the configuration a name; in this case, that name is ConfigName, but you can choose any other name that suits your needs.
The Script Path merely shows the location of the File within the same directory and the Path of the scratch file.
The configuration will be added and set once you click Apply and dismiss the window.
Therefore, you are prepared to run the code after configuring the setup.
Let's run the example and look at the results.
Check out the output now that PyCharm has run the application.
We received the correct output in the Python Console, as shown in the screenshot.
Python Debugging Tool
With PyCharm, debugging is simple. Setting up breakpoints is as simple as clicking on the code's left side, which places the red dot.
It is as it appears in the picture below. You can set as many breakpoints as you like, segment the code, and run them.
You may also use the Watch option to see what inputs are made into certain variables. This is unquestionably a major plus, and when combined with the inline debugger, it gives programmers a significant edge.
Overall, this improves readability and documentation and simplifies the testing and debugging processes.
Let's look at some basic tips and tactics you can utilize when using PyCharm in the following section of this PyCharm Tutorial blog.
PyCharm Beginner's Guide: Tips And Tricks
You may use a lot of tips and tricks when programming with PyCharm. I'll keep it relatively beginner-friendly for simplicity's sake so that most of your readers can connect with the ideas immediately.
Duplicating lines of code is as simple as choosing the lines you want to duplicate and using the Ctrl + D keyboard shortcut. This guarantees that the selected lines will be copied immediately after the selection onto the new lines. Keep in mind that the indentation will match that of the first line.
Ctrl + D before:
Following Ctrl + D
Using the keyboard shortcut Alt + Shift + C, you can track and traceback changes to individual files as well as the entire project. This guarantees a certain level of
readability and lets you know any recent modifications that improve your understanding of the project lifecycle.
Check out the photo below:
Assume you have a variable named "x," and you have used it around 100 times in your program before deciding that "x" must now become "y." Finding every "x" and replacing it with "y" is the standard procedure, right? No, actually!
The variable and the refactor option are all required to use PyCharm's intelligent refactoring technique. If you modify it once, it will affect wherever that variable occurs with only one click. The major benefit is that, within a specific scope, this also works flawlessly for a variable.
This is after refactoring and changing the variable; everything in the scope only required one click. A significant benefit, yes?
PyCharm offers similar functionality for intelligent typing as Microsoft's Visual Studio. If there is a chance that the IDE will make a reliable prediction as to what you could type next, it makes sure that you don't have to type everything out.
Check out the photo below:
Scroll down the Alt key to pick a specific code section. This will select the entire column. This can be used to quickly change the indentations or indent more quickly. However, it can also be used to update several statements in a single column, saving time and effort compared to manually.
To see the choice more clearly, look at the following image:
