Are you still stuck with the syntaxerror: invalid non-printable character u+00a0 error message in Python?
Well, we got you! Just continue reading.
In this article, we’ll walk you through how to troubleshoot the syntaxerror: invalid non-printable character u 00a0 that gives you a hard time.
Apart from that, we will give you the information that will help you to understand this error.
What is “syntaxerror: invalid non-printable character u00a0”?
The error message syntaxerror: invalid non-printable character U+00A0 occurs when your Python code contains a non-printable character.
For example:
from PIL import Image
img = Image.open("sample.png")
Output:
SyntaxError: invalid non-printable character U+00A0This error message is raised when Python encounters an invalid non-printing character in its code. These characters are like the zero-width space or byte-order mark.
That is not visible in your code editor but can cause this error when running the code.
This character is often used in HTML to prevent line breaks, but it can cause issues in other programming languages
Why does “invalid non-printable character u+00a0” SyntaxError occur?
This error message usually happens when you have copied a code from a web page or other sources, such as a PDF document or any other formatted text source.
Here are the additional reasons why this error keeps on bothering you:
❌ If the file containing the code is encoded using an incompatible character encoding scheme, it can lead to the presence of non-printable characters and result in the SyntaxError.
❌ Oftentimes, certain key combinations or shortcuts can inadvertently insert non-printable characters into the code. These characters can go unnoticed but can cause the error to occur.
How to fix “syntaxerror: invalid non-printable character u+00a0”?
To fix the syntax error invalid non-printable character u+00a0, double-check your Python code to see which line is causing the error.
Then, copy that line into a non-printing character viewer tool (soscisurvey). If you see it, remove those unwanted characters and bare in mind to remove all of them before copying it back to your code.
Conclusion
In conclusion, the error message syntax error: invalid non-printable character U+00A0 occurs when your Python code contains a non-printable character.
This article already discussed what this error is all about and multiple ways to resolve this error.
By executing the solutions above, you can master this SyntaxError with the help of this guide.

Frequently Asked Questions
Why indentation SyntaxError happens
Python uses whitespace for code structure. Mixing tabs and spaces, inconsistent indent levels, or unexpected dedents all raise IndentationError (a SyntaxError subclass).
Common triggers
- Mixed tabs and spaces. Python 3 rejects mixing. Configure your editor to convert tabs to spaces.
- Inconsistent indent. First line uses 4 spaces, second uses 2 — raises IndentationError.
- Empty function body. Function definition needs at least one statement. Use
passas placeholder. - Copy-paste from web. Web-copied code often has invisible unicode spaces (U+00A0 non-breaking space) that look like normal spaces but fail.
- Unexpected dedent. Closing a block before it was properly opened.
Diagnostic pattern
# BAD — empty function body
def compute():
# IndentationError: expected an indented block
# GOOD — use pass
def compute():
pass
# BAD — mixed tabs and spaces (invisible!)
def bad():
x = 1 # spaces
y = 2 # tab
return x + y
# GOOD — PEP 8 says 4 spaces, always
def good():
x = 1
y = 2
return x + y
# Configure editor to show whitespace and use spaces:
# VS Code: "editor.renderWhitespace": "all"
# "editor.insertSpaces": true
# "editor.tabSize": 4
Best practices
- Configure editor to convert tabs to 4 spaces. Standard PEP 8.
- Use ruff or black. Auto-formatters enforce consistent indentation.
- Enable “show whitespace” in your editor while debugging.
- Use “python -tt file.py” to detect inconsistent tab/space use explicitly.
Official documentation
What is Python SyntaxError and what causes it?
SyntaxError is raised when Python’s parser can’t understand your code. Common causes: missing colon (def foo() instead of def foo():), unmatched parentheses or brackets, incorrect indentation, mixing tabs and spaces, missing comma in a list, or using a Python 3 feature in a Python 2 interpreter (or vice versa). The error points to a line, but the actual issue is often on the line BEFORE.
How do I fix ‘unexpected EOF while parsing’?
Python ran out of code while expecting more, usually unclosed parenthesis, bracket, brace, or quote. Scroll up from the error line and count opening vs closing pairs. Use an IDE with bracket matching (VS Code, PyCharm) to highlight pairs. Common gotcha: a triple-quoted string that’s missing its closing triple-quote.
Why does my syntax error point to a line that looks correct?
The actual error is often on the line BEFORE the one Python reports. Python reads code until something doesn’t parse, then reports the position where it gave up, not where the user’s mistake started. Check the line above the reported error for missing colons, commas, or closing brackets.
Why does ‘print x’ raise SyntaxError in Python 3?
Python 3 made print a function, so print(x) is required. The bare ‘print x’ syntax was Python 2 only. If you’re following an old tutorial, check whether it targets Python 2 (released 2008) or Python 3 (your current interpreter). Update all print statements to print(…) function calls.
