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.

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

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

1 2 3 4 5 6 7

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.
What's the Unladen Swallow title below my name and avatar?

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

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