Get duration of .wav from sox in python

Question

I know how to print the duration of the .wav file using sox at the Linux command.

soxi -D input.wav

So I used this syntax in python.

subprocess.call(['soxi', '-D', input.wav])

But I'd like to save the duration(seconds) in a variable. How do I get it in a variable?

using)

wavduration = subprocess.call(['soxi', '-D', input.wav])
print(wavduration)

output)

4.000000
0

This is not the right way to do it...
