Why does my Python always say "Syntax Error" when using the (f" function?

Whenever I try running any programs with the (f"... function my Python always shows up a Syntax Error Message.

from easy_terminal import terminal

@terminal()
def hi():
    print("Hello!")


@terminal()
def hello(answer: str = "world"):
    print(f"Hello {answer}!")

The final line of code just doesn't run because of the final set of quotation marks in the last line. I've had a similar problem with other programs, all of which have used this function.

The f-string feature is only available from Python 3.6 and onwards. The error might be due to using a Python version that's older than 3.6.

What to do?

1- Check your Python version using:

import sys
print(sys.version)

If your Python version is below 3.6, you would need to update it to use f-strings.

If your Python version is 3.6 or above and you're still facing issues, then the error might be something else, not related to the use of f-strings. In that case, you could share the exact error message you're getting for further assistance.

2- Ensure that you're not using any unusual characters within the f-string. It should follow this format:

variable = 'world'
print(f'Hello, {variable}!')

Output: Hello, world!

Here the f outside the quotation marks denotes that it is a formatted string, and the curly braces {} are used to evaluate variables within the string.
