Toolbox for developers / Python online test

Python syntax checker

Python tester allows to check your Python code syntax (Python 3), and find Python errors. This Python code checker tool highlights and goes to line with a syntax error.

To check your code, you must copy and paste, drag and drop a Python file or directly type in the Online Python editor below, and click on "Check Python syntax" button.

You can see the user guide to help you to use this python checker tool.

Python code







User guide

How to check the syntax of your Python code:

  • First, Drag and drop your Python file or copy / paste your Python text directly into the editor above.
  • Finally, you must click on "Check Python syntax" button to start code checking.

It is quick and easy to analyze python code!


Python code checker tool

Python is a server-side scripting language, but can also be used as a general-purpose programming language.

Python error checker tool allows to find syntax errors (lint). You can test your Python code online directly in your browser.

If a syntax error is detected, then the line in error is highlighted, and it jumps to it to save time (no need to search the line).

It can be useful to make online test to save time (deployment ...).

Note: This tool no longer offers sandbox, it was not good enough.


About Python

Python is an interpreted programming language, it features a dynamic type system and automatic memory management (garbage collector). Python is available for many operating systems.It has a large standard library.

Python formatting is visually uncluttered, and often uses English keywords rather than punctuation. Python uses whitespace indentation instead of curly brackets to delimit blocks.

Python is often used as a programming language in high school and higher education, especially in France (I am French).

Assume we are testing a variable is_sunny in a while loop. is_sunny = “n” The above statement is declared. Write a while clause that will continue executing a loop until is_sunny is ‘y’.

while True: n=int(input("saisir un entier entre 20 et 30") if (n<20) or (n>30): break can you correct it please


Cyril (admin)-2019-11-20 20:51
it is missing a parenthesis, and there is a indentation error:

<pre>while True:
n=int(input("saisir un entier entre 20 et 30"))
if (n<20) or (n>30):
break

</pre>
