How Do I Fix 'SyntaxError: Non-ASCII Character...' Errors in My Python Code?

Troubleshooting "SyntaxError: Non-ASCII Character..." Errors in Python Scripts

Encountering a "SyntaxError: Non-ASCII character..." error while attempting to utilize non-ASCII characters in Python scripts can be frustrating. This error arises because the script is attempting to employ a character that falls outside the confines of the ASCII character set, leading the interpreter to raise an exception.

Understanding the Error

The error message points to a specific character in the file that is causing the issue. This character is represented by a hexadecimal code, such as 'xa3' in your example.

In Python 2, this error occurs because the script assumes an ASCII encoding, which does not include the pound sign (£). In Python 3, the error occurs if the file is saved with a character encoding that does not support the pound sign, such as Latin-1.

Resolving the Issue

To resolve this issue, you can use one of two approaches:

1. Declare the File Encoding: Add an encoding declaration at the top of the script, such as "# -- coding: utf-8 --". This will inform the interpreter that the script should be treated using a specific encoding, such as UTF-8, which supports non-ASCII characters.
2. Encode Strings Manually: If you only need to embed non-ASCII characters in specific strings, you can encode them manually. This can be done using functions such as str.encode() in Python 2 or bytes().decode() in Python 3.

Using the Pound Sign Literal

If your goal is to include the pound sign literal (£) in your code, you will need to choose an encoding that supports it throughout the file. UTF-8 is a widely used encoding that supports most common characters, including the pound sign.
