[New-bugs-announce] [issue43808] Add .isfloat() method to str

[JimmyCarlos]

New submission from JimmyCarlos <jonathansagnella at yahoo.com>:

Hello Python Community!

One feature I think would be helpful would be a method to see if a str can be safely converted into a float. Currently, this is not doable without a long regex or a try-except block, as numbers like "-3.52" contain non-numeric symbols.

My suggestion is to make a new boolean method on the str class. Code-wise, it would behave quite similarly to this code:

def isfloat(s:str) -> bool:
    try:
        float(s)
        return True
    except:
        return False


I appreciate your feedback, so what do you all think?
