format strings syntax error

[VikramSuh]

I'm a noob doing an introductory lesson on format strings. The example given in the lesson keeps giving an error, even when I directly copy/paste. Here's the code:

my_height = 80
print(f"He's {my_height} inches tall.")

The error I get says this:

Error:
  File "/home/main.py", line 9                                                                                                                                                     
    print(f"He's {my_height} inches tall.")                                                                                                                                        
                                         ^                                                                                                                                         
SyntaxError: invalid syntax  

I looked for some examples online and was able to make it work like this:

my_height = 80
print("He's {} inches tall.".format(my_height))

So what's wrong with the syntax in the lesson I was using? Is the example in the lesson totally wrong?

You must be using a python version before 3.6. f-strings as in your first snippet were introduced in python 3.6

Yup, that was it! I've been practicing using an online editor and when I checked I saw it was an older version. I found a 3.6 one and now it works.

Lesson learned, thanks!
