If you are a beginner in Python programming, then it is common to encounter errors while coding. One such error is the ‘invalid token’ error. It can be frustrating when your code does not run due to this error. In this article, we will discuss various reasons for this error and how to troubleshoot and fix it.

Causes of ‘Invalid Token’ Error

The ‘invalid token’ error may occur due to several reasons, such as using a reserved keyword as a variable name, incorrect syntax, or incomplete code. Let’s take a look at each cause in detail.

Using Reserved Keyword as a Variable Name

Python has several keywords reserved for specific functions such as if, else, while, and def, among others. If you use any of these keywords as a variable name, you will encounter the ‘invalid token’ error.

Incorrect Syntax

The ‘invalid token’ error may also occur due to incorrect syntax. For example, if you forget to close a bracket, add an extra space, or use the wrong operator, you may get this error.

Incomplete Code

If you run a code with incomplete statements or unmatched brackets, you will get the ‘invalid token’ error. Ensure that all your statements are complete, and all brackets are correctly matched.

Troubleshooting ‘Invalid Token’ Error

Now that we know the causes of this error let’s look at some troubleshooting tips to fix it.

Check Your Code for Typos

Check your code carefully for typos, spelling mistakes, or syntax errors. Ensure that all brackets are correctly matched, and all statements are complete.

Use a Code Editor with Syntax Highlighting

A code editor with syntax highlighting can help you identify syntax errors quickly. The editor highlights incorrect syntax in different colors, making it easy to detect and fix errors.

Refer to Python Documentation

If you encounter this error due to using a reserved keyword as a variable name, refer to Python documentation for a list of reserved keywords. Change the variable name to something else to fix the error.


The ‘invalid token’ error is common in Python programming and can be solved easily. To avoid this error, follow good coding practices, use a code editor with syntax highlighting, and refer to Python documentation when necessary. With practice and experience, you will encounter fewer errors and become a proficient Python programmer.

Python Tips: How to Troubleshoot ‘Invalid Token’ Errors in Your Code

As a beginner to Python programming language, you might have encountered an error message that says invalid token while writing code. This error occurs when Python’s parser cannot understand the code you’re trying to write. Debugging this type of error can be challenging and can consume a lot of time. However, troubleshooting invalid token errors can become more comfortable if you follow these tips.

The first thing to do is to take a closer look at the line where the error occurred, particularly the characters immediately before the invalid token. Most of the time, invalid token errors are caused by syntax errors like missing a parenthesis or quotation mark, having an extra comma or semicolon, or having inappropriate indentation. Check whether all parentheses, braces, and brackets are appropriately balanced. Verify that strings, variables, and functions are correctly named and properly declared. Indentation should also be consistent throughout your code.

Another thing you can do is to ensure that you’re using the correct version of Python. Also, check whether an incorrect character encoding used in your source code file causes the syntax errors. Check if there are non-ASCII characters being used and whether they’re encoded correctly. Use an editor with syntax highlighting capabilities to make it easier to detect syntax errors.

In conclusion, invalid token errors are common in Python Programming, but debugging them isn’t rocket science. By understanding the reasons for these errors and how to avoid them with the tips mentioned, you can write better and error-free Python code. Happy coding!
