Turning if statement into a single line while setting a variable

I am trying to check if something exists in a dictionary and then if it does, set it to a variable.

Here is what I am doing:

myobj = None
if myvar in mydict:
    myobj = mydict[myvar]

I got it down to this:

if myvar in mydict: myobj = mydict[myvar]

But what I am after is something like this (pseudo):

myobj = mydict[myvar] if myvar in mydict

Basically I am looking into a dictionary with a : layout. If my string is in the dictionary, then I want the value (class object) to be set my variable.

`myobj = mydict.get(myvar)`.. – Martijn Pieters Jul 16 '19 at 14:59

and you pseudocode is only missing an `else None`; `myobj = mydict[myvar] if myvar in mydict else None`, a verbose way of spelling `myobj = mydict.get(myvar)`. – Martijn Pieters Jul 16 '19 at 14:59
