Impossible, for now, to use an f before a string in a print. for example : print(f"Hello {name}, how are you ?") about epsilon

[andyWiles]

It would be convenient to use f before a string in a print or a return :
print(f"Hello {name}")
return f"s={s} and t={t}"

Thank you, a ticket has been created internally

maybe this is due to the fact that epsilon uses the micropython interpreter, defining properties for attributes is also kinda difficult to do on the numworks
as an alternative you can do
print("Hello {}".format(name))
return "s={} and t={}".format(s, t)
