f-strings giving SyntaxError?

问题

I am getting an error message with my Atom reader here, where it is suggesting the first print.(f"message") is delivering an error:

File "/Users/permanentmajority/Desktop/Coding/learnpythonbook.py", line 75
    print(f"Let's talk about {my_name}.")
                                       ^
SyntaxError: invalid syntax
[Finished in 0.077s]

Code:

my_name = 'Zed A. Shaw'
my_age = 35 # not a lie
my_height = 74 # inches
my_weight = 180 #lbs
my_eyes = 'Blue'
my_teeth = 'White'
my_hair = 'Brown'

print(f"Let's talk about {my_name}.")
print(f"He's {my_height} inches tall.")
print(f"He's {my_weight} pounds heavy.")
print("Actually that's not too heavy.")
print(f"He's got {my_eyes} eyes and {my_hair} hair.")
print(f"His teeth are usually {my_teeth} depending on the coffee.")

回答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

回答2:

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.

回答3:

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.

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 checkout here-

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

here

it works
