title: Null values and type
body: <p>Is there any code from which we get only the null values variables and the type of that variable?</p>
  <p>df.isnull().sum() is used to get the null values
  df.info() is used to get the type of variable.
  or dtypes is used</p>
  <p>but can we get the same thing with the one liner code?? like we get the table where there is variable name with missing values in 1st column and their type info in 2nd column and % of missing value in 3rd column</p>
