Know About Code Visualizer

Code Visualizer - Python Tutor

Introduction

Generally, a code visualizer is a which helps to visualize the code and helps to understand the code in a better way and clearly by seeing how the code is executed, how the memory is allocated, where the result is stored, etc.

In this blog, we are going to see about the code visualizer called "Python Tutor". Don’t get confused by the name. In this Python Tutor, we can be able to visualize our code in five languages such as C, C++, Java, Python, and Javascript.

How to visualize your code using Python Tutor?

Let’s discuss this in detail,

Step 1

When you open the link mentioned above in the Introduction part, you were directed to the home page of the Python Tutor [Home page is shown in the above image]. On the home page itself, you can find the option called "Edit the code". By clicking that option, you will be redirected to the coding page shown below.

Step 2

On the coding page, you can see the drop-down box at the top of the coding area, there you can choose the programming language [ C, C++, Java, Python, and Javascript ].

Step 3

After choosing the programming language now you can visualize your code by copy-pasting your code from the file or by writing your own code in the coding area.

Step 4

After writing the code in the code area, now it’s time to visualize your code. Click the "Visualize Execution" button located below the coding area, then you will be redirected to the new page shown below.

On this page you can notice two arrows, one is in light green color which shows the line that was executed just before and the other one is in red color which shows the line that is to be executed next.

Step 5

After giving the user inputs, You can see what are the inputs that you have given, and the memory allocated for that input values in the top-right side of the page.

Below the coding area, you can see four buttons are available that are "First", "Prev", "Next" and "Last".

• "First" - If you press this button, it will take you to begin of the code where the executions start.
• "Prev" - The previous button is used to go back to one line that was executed before.
• "Next" - If you press this button, it will take you to the next line that is to be executed next.
• "Last" - If you press this button, it will take you to the end of the program.

Finally, After giving the user inputs and pressing the Next key 2 times, now you can be able to see the output of the code and how the input values & result is stored in the memory frame.

Conclusion

Python Tutor the code visualizer helps you to visualize your code in five languages [ C, C++, Java, Python, and Javascript ] with this you can execute and visualize your code which helps to understand how the code is executed, how the memory is allocated, how the control is transferred from one to another, etc.
