hi,
I am a beginner, but still you must see this prob.
See this code:

If i will Put the value of  X = 1,
it will show Not Valid! ,
At this moment python should show an error that , how can be the variable X  , be int and float at the same time ,
But still it shows Not Valid!
I think it needs to be fixed to make python more intelligent language.

if isinstance(x, int) and isinstance(x, float) and x=='1':
    print("Valid type!")
else:
    print("Not valid!")
