Handling null or empty entries from Entry Widget

[KevinBrown]

I am taking values from Entry widgets, some of which can be a null /empty and to run them into SQLite.

Suct = float(EntSuct.get())[/quote]

How should I handle this to avoid these kinds of errors?

Exception in Tkinter callback
Traceback (most recent call last):
  File "C:\Users\Kevin\AppData\Local\Programs\Python\Python37-32\lib\tkinter\__init__.py", line 1705, in __call__
    return self.func(*args)
  File "C:\MyScripts\Pump_Calc.py", line 124, in FileSave
    Suct = float(EntSuct.get())
ValueError: could not convert string to float: 

By the way.

I am no admin on this site, but for context you can read this: swallow

In Python there is try...except for handling errors.
