How to know if the Variable is Categorical or Numerical if all it contains is Digits?
<dataframename>.info() will give the total count of each variable along with whether it is non-null and its datatype like float64,object,int64 etc
I have a dataset which has several Variables. 
I want to determine that how can we judge for a variable if it is categorical or numerical other than the method of unique value counts, as for instance one of my variable Disease Type has 31 Unique Values whereas other Variable Distance from Office has 25 Unique Values, both in the form of numbers.
