f-strings giving SyntaxError?

Question

I tried this code, following along with a tutorial:

my_name = 'Zed A. Shaw'

print(f"Let's talk about {my_name}.")

But I get an error message highlighting the last line, like so:

    print(f"Let's talk about {my_name}.")
                                       ^
SyntaxError: invalid syntax

Why?

_{If you get an error like this from someone else's code, do not try to fix it yourself - the other project simply does not support your Python version (One example: Using pytesseract on Python 2.7 and Windows XP). Look for an alternative instead, or check the project's documentation or other support resources for a workaround.}

_{In particular, the built-in pip package manager has an issue where newer versions of pip require a newer Python version, so old installations cannot upgrade pip past a certain point. See Installing pip is not working in python < 3.6 or Upgrading pip fails with syntax error caused by sys.stderr.write(f"ERROR: {exc}") for details.}

_{If an external tool warns about the problem even though Python supports the feature, update the tool. See Getting invalid syntax error when using Pylint but code runs fine for an example.}

_{This question is specifically about the situation where any attempt to use f-strings fails (the ^ in the error message will point at the closing quote). For common problems with specific f-string syntax, see How do I escape curly-brace ({}) characters in a string while using .format (or an f-string)?, f-string formula inside curly brackets not working, Discord.py - SyntaxError f-string: empty expression not allowed, How to use newline '\n' in f-string to format output in Python 3.6?.}

Answer 1

I think you have an old version of python. try upgrading to the latest version of python. F-string literals have been added to python since python 3.6. you can check more about it here

Answer 2

This is a python version problem.

Instead of using

print(f"Let's talk about {my_name}."

use

print("Let's talk about {}.".format(my_name))

in python2.

Your code works on python3.7.

Check it out here:

my_name= "raushan"
print(f"Let's talk about {my_name}.")

Answer 3

Python Interpreter causes the following issue because of the wrong python version you calling when executing the program as f strings are part of python 3 and not python 2. You could do this python3 filename.py, it should work. To fix this issue, change the python interpreter from 2 to 3. 

Answer 4

f-strings were added in python 3.6. In older python versions, an f-string will result in a syntax error.

If you don't want to (or can't) upgrade, see How do I put a variable inside a String in Python? for alternatives to f-strings.

Answer 5

I think this is due to the old version. I have tried in the new version and the executing fine. and the result is as expected.

Answer 6

I believe the problem you are having here is down to you using python 2 without realizing it. if you haven't set it up on your machine to have python 3 as your default version you should execute python3 in your terminal instead of the standard 'python' command.

I had this problem so hopefully, this answer can be of help to those looking for it.
