A good helper for beginners of programming languages, a visual programming tool that supports 7 languages such as python and Java

For students who are new to programming, there is a big difficulty, that is, they can not understand what each piece of code means, what functions can be achieved. U nderstanding the key to the ability to execute each piece of code should be a concern for students learning programming languages. This article brings you an artifact that makes it easy for beginners to understand the functional processes of each piece of code implementation.

What exactly is the process of implementing a sorting, backtracking, recursive algorithm? Why do some test cases always get through?

Writing it manually step by step is obviously cumbersome, or with the help of IDE output the results of each step as a debug log to the console to see what's going on at each step.

I've seen the news that VS Code is ready to add the visual debugging process, which I'm looking forward to, but it's not available yet.

python Tutor

Python Tutor is an online visualization tool for code execution processes.

def listSum(numbers):
    if not numbers:
        return 0
    else:
        (f,rest) = numbers
        return f * listSum(rest)


myList = (1,(2,(3, None)))
total = listSum(myList)

You can glue this code to python Tutor edit box by clicking OnVisualize Execution to execute your code dynamically and show you how each step is performed in real time.

The effect of the change is shown below (implement the process picture over, excerpt a few of them):

The process of changing the number of programs is presented to you alive, and it's clear enough.

python tutor I more as a program to appear self-explanatory errors, run once on the site, perform process comparison, find the cause of the error, fast and accurate.

The tool is then named Python Tutor but it supports more than Python It currently supports the following programming languages:

• Python
• Java
• C
• C++
• JavaScript
• TypeScript
• Ruby

Among them, the more comprehensive support is Python for Python it Python 3.6 Python 2.7 Python with Anaconda

Python is a programming language that relies heavily on third-party packages, so toolkits such as numpy pandas pprint are often used in development. The default Python 3.6 and Python 2.7 have only some standard libraries and no third-party packages.

So, if you use a third-party toolkit in your code snippet, you can choose Python with Anaconda because Anaconda installs commonly used toolkits by default.

However, using Python with Anaconda is slower.

Personally, this tool is more suitable for programming beginners, such as students facing school recruitment, this tool is very helpful for familiar with programming, can speed up your learning efficiency, improve the understanding of programming language.
