#16 Python Tutorial for Beginners | Working with PyCharm | Run | Debug | Trace | py file
Introduction to Python
In this video, the instructor introduces Python and explains how to write code in a file instead of an interactive console.
Writing Code in a File
- To write multiple lines of code, create a file with the extension ".py".
- Save the file and store it anywhere you want.
- To run the code, click on "Run Module" or use the command prompt and navigate to the folder where your file is saved.
- Use the command "python" followed by the name of your file to run it.
Starting with Simple Code
- Start with simple code like printing "Hello".
- Before running your code, make sure to save it using "Control + S".
- Navigate to where you want to save your file and give it a name with the extension ".py".
- Run your code using either "Run Module" or through the command prompt.
Importance of Learning Basics First
- It's important to learn the basics before jumping into big projects.
- Working step by step will help prevent getting stuck later on.
- Don't rush into big projects without first mastering basic concepts.
Writing and Running Python Code in PyCharm
In this section, the speaker explains how to write and run Python code using PyCharm.
Getting Started with PyCharm
- To get started with PyCharm, click on "Create New Project" and enter a project name.
- Once you have created a project, you can create a new file by right-clicking and selecting "New File".
- When creating a new file, make sure to give it the extension ".py" so that it is recognized as a Python file.
Writing Code in PyCharm
- To write code in PyCharm, simply open the file you want to work on and start typing.
- You can change the font size or color theme by going to "File" > "Settings" > "Editor".
- To run your code, click on the "Run" button and select "Run 'filename.py'".
- You can also run your code by right-clicking on the file and selecting "Run 'filename.py'".
Debugging Code in PyCharm
- One advantage of using an IDE like PyCharm is that you can debug your code.
- To debug your code, click on the "Debug" button instead of the "Run" button.
- This will allow you to trace what is happening in your code and see how values are changing.
Debugging in PyCharm
In this section, the speaker explains how to debug code in PyCharm and the importance of tracing.
Setting a Breakpoint
- To debug code in PyCharm, set a breakpoint by clicking on the line number and then clicking on "debug".
- Alternatively, you can press F8 to move to the next line.
- The variable section shows the type and value of variables at each step.
Importance of Tracing
- Tracing is important when working on large projects with many lines of code.
- To trace, put a breakpoint on a specific line and use F8 to move through each line.
- This allows you to identify bugs and understand what is happening at each step.
Conclusion
The speaker concludes by discussing future topics that will be covered in the series.
- The series will focus more on using PyCharm for coding.
- However, there may still be some videos that use other IDEs or languages.
- Viewers are encouraged to ask questions and share the series with friends.
