Getting an “invalid syntax” when trying to perform string interpolation

Solution for Getting an “invalid syntax” when trying to perform string interpolation
is Given Below:

I have recently been learning python 3 and I cannot get any examples involving string interpolation (formatting) to work.

In [1]: state = "Washington"

In [2]: state
Out[2]: 'Washington'

In [3]: my_message = f"I live in {state}"
File "<ipython-input-3-d004dd9e0255>", line 1
my_message = f"I live in {state}"
SyntaxError: invalid syntax

I figured my machine was defaulting to python 2, but a quick check reveals:

Python 3.5.2 (default, Nov 17 2016, 17:05:23) 
Type "copyright", "credits" or "license" for more information.

IPython 5.2.2 -- An enhanced Interactive Python.

I am on Ubuntu 16.04:

python3 --version
Python 3.5.2

Am I just overlooking basic syntax? I have run the same commands on a few computers from fellow students and it seems to execute just fine.

As suggested by Josh Lee in the comment section, that kind of string interpolation was added in Python 3.6 only, see What’s New In Python 3.6 (here it’s called “PEP 498: Formatted string literals”).

You, however, seems to be using Python 3.5.2, which does not support that syntax.

This is a pretty old question and not sure if answered somewhere else, but ran into same problem and landed on some confusing pages. Figured out a couple of minutes later. Below line should work.

my_message = "I live in {}".format(state)

.format works for 3.5. Documenting it here for someone who may need it for similar issue.

What worked for me (in python 3.8.5 in sublime) was removing the f.

message = "I live in {state}"

I find it easier than .format(state)
