Is there better way of writing this code:
def add (exe1, exe2):
try:
a = float (exe1)
b = float (exe2)
total = float (a + b)
except ValueError:
return None
else:
return total

You can have it all inside a try/except block (calculation and return):
def add(exe1, exe2):
try:
return float(exe1) + float(exe2)
except ValueError:
return None
Also note, the default return value from function is None, so the second return is not really necessary (you could have pass instead), but it makes code more readable.

You can also use contextlib.suppress, if you find it more readable.
from contextlib import suppress
def add(exe1, exe2):
with suppress(ValueError):
return float(exe1) + float(exe2)
See the documentation here.
