How to Handle 'SyntaxError: Non-ASCII...' and 'SyntaxError: Non-UTF-8...' Errors in Python?

Non-ASCII Characters in Python Scripts: "SyntaxError: Non-ASCII..." and "SyntaxError: Non-UTF-8..."

While working with Python 2 or 3, you may encounter errors like "Non-ASCII character..." or "Non-UTF-8 code..." when using non-ASCII text within string literals. These errors stem from a mismatch between the encoding of your source code and the presence of non-standard characters.

To address this issue in Python 2, where ASCII encoding is typically assumed, you should specify UTF-8 encoding by adding the line "# -- coding: utf-8 --". This declaration ensures that Python interprets your code using UTF-8 encoding, which supports a wider range of characters.

In Python 3, the default encoding is UTF-8, but conflicts can arise if your script is saved using a different encoding. To correct this, explicitly declare the encoding at the top of the file.

For example, if your script contains Latin-1 characters, you should declare the appropriate encoding as follows:

# -*- coding: latin-1 -*-

Alternatively, you can specify the encoding for individual strings directly within the code using the encode() method:

london_bus = "£4.50".encode("latin-1")  # Set the encoding for this specific string

By following these guidelines, you can avoid encoding errors and ensure that your Python scripts handle non-ASCII characters correctly.
