Why Am I Getting a SyntaxError with f-Strings in Python?

SyntaxError with f-Strings

When attempting to utilize f-strings within a Python codebase, users may encounter the following SyntaxError:

SyntaxError: invalid syntax

This error often stems from using an outdated Python version. F-string literals were introduced in Python 3.6, and if your code is running on an earlier version of Python, the interpreter will not recognize the f-string syntax.

Resolution

To resolve this issue, ensure that your Python version is upgraded to 3.6 or later. Follow the steps outlined below:

1. Open your terminal or command prompt.
2. Type the following command:

python --version

3. If your Python version is less than 3.6, update it using the following command:

python -m pip install --upgrade pip
python -m pip install --upgrade setuptools
python -m pip install --upgrade wheel
python get-pip.py
python -m pip install --upgrade pip
pip install --upgrade pip --user

4. Restart your Python IDE or command shell.

Once you have upgraded your Python version, f-strings should work as expected.
