One liner for dictionary comparison in python

Question

What's the one-liner for the below code?

for k,v in d2.items():

    if d1.get(k,0) < v:

        return False

return True

I tried this but it's invalid syntax.

return False if d1.get(k,0)<v for k,v in d2.items() else True

Why?

Answer 1

Use any or all:

return not any(d1.get(k, 0) < v for k, v in d2.items())

or

return all(d1.get(k, 0) >= v for k, v in d2.items())
