Improved error messages
-----------------------

* The interpreter now provides helpful suggestions when it detects typos in Python
keywords. When a word that closely resembles a Python keyword is encountered,
the interpreter will suggest the correct keyword in the error message. This
feature helps programmers quickly identify and fix common typing mistakes. For
example:

.. code-block:: python

>>> whille True:
... pass
Traceback (most recent call last):
File "<stdin>", line 1
whille True:
^^^^^^
SyntaxError: invalid syntax. Did you mean 'while'?

>>> asynch def fetch_data():
... pass
Traceback (most recent call last):
File "<stdin>", line 1
asynch def fetch_data():
^^^^^^
SyntaxError: invalid syntax. Did you mean 'async'?

>>> async def foo():
... awaid fetch_data()
Traceback (most recent call last):
File "<stdin>", line 2
awaid fetch_data()
^^^^^
SyntaxError: invalid syntax. Did you mean 'await'?

>>> raisee ValueError("Error")
Traceback (most recent call last):
File "<stdin>", line 1
raisee ValueError("Error")
^^^^^^
SyntaxError: invalid syntax. Did you mean 'raise'?

While the feature focuses on the most common cases, some variations of
misspellings may still result in regular syntax errors. (Contributed by Pablo

Comment thread
pablogsal marked this conversation as resolved.
Outdated

* When unpacking assignment fails due to incorrect number of variables, the
error message prints the received number of values in more cases than before.
