Convert timedelta value to float

Question

I need to save a timedelta value into a float type fields.

Here is my code:

if self.end_time and self.start_time:
        timediff =self.end_time - self.start_time // Here i get a time.delta value
        self.duration = // here i get an error

TypeError: float() argument must be a string or a number, not
'datetime.timedelta'

How can I resolve this?

The code above is not valid Python: `//` is not a comment marker in Python, and your `self.duration =` assignment is missing exactly the code fragment which is causing your problem. Please paste something that actually exhibits the behaviour you describe. — Zero Piraeus, Feb 26 '19 at 13:59

The code in your question is incomplete, but assuming you're actually doing something like this:

self.duration = float(timediff)

… and what you want is the total number of seconds represented by timediff as a float, you can get that using the timedelta.total_seconds() method:

self.duration = timediff.total_seconds()

This returns a float, so no conversion is necessary.
