Thanks!

Do not try it, though, with a expression such as
import os; os.system('rm -rf ~/*').

If you want something safer, https://github.com/pydata/numexpr has an 
expression function that will do the same thing.


Another, safer :

s = "42 + 5 * 12"
float(eval(f"f'{{{s}}}'"))
102.0

Is it absolutely safe though?
