Based on the example here , I tried to run the following code snippet but failed:
run_mode, num_repeats, num_runs = 'short', 5, 1000
s = f"""
{'-'*40}
# Operator Micro-benchmarks
# Run_mode: {run_mode}
# Num_repeats: {num_repeats}
# Num_runs: {num_runs}
{'-'*40}
"""
print(s)
The error is as follows:
$ python test.py
File "test.py", line 11
"""
^
SyntaxError: invalid syntax
I’m surprised at this error message because I don’t see anything wrong with my code. Any tips will be appreciated.
Regards,

I ran the same code on colab, it works.
Works fine for me.
What version of Python are you using? I can only duplicate that error in Python 2.7. That is no longer supported and is extremely out of date. You should be using Python 3.10.

Unsurprising, f-strings were added in version 3.6.

Hongyi, please include python version with questions.
I don’t have the pythons command at all:
werner@X10DAi:~$ pythons
Command 'pythons' not found, did you mean:
command 'python0' from snap python0 (0.9.1)
command 'python2' from deb python2 (2.7.18-3)
command 'python3' from deb python3 (3.10.4-0ubuntu2)
See 'snap info <snapname>' for additional versions.

Hi Daniel R Stromberg , thank you for letting me know your wonderful tools.
Nowadays, git is the de facto standard tool for distributed code management. So, I want to know whether you have these tools resided on git based repositories?
