Use a function in mydict [variable]. KeyError: <function myfunction at 0x7f6b65a0f7f0>
Question:
Until now I used a dictionary and a variable in the following way and it worked correctly:
if mydict[variable] == value:
Now I would like to replace the variable with the return of a function. I tried to write like this
if mydict[myfunction] == value
but I get an error:
KeyError: <function myfunction at 0x7f6b65a0f7f0>
How can I solve?
Answers:
You need to invoke the function (ie. make it run).
You do this by putting () after the function name.. myFunction()
if mydict[myfunction()] == value
What you had done is pass a reference to the function and tried to use that as a key in your dictionary rather than passing the result returned by your function and using that as a key.
