Pandas: convert dtype 'object' to int

Question

I\'ve read an SQL query into Pandas and the values are coming in as dtype \'object\', although they are strings, dates and integers. I am able to convert the date \'object\'

Answer 1

My train data contains three features are object after applying astype it converts the object into numeric but before that, you need to perform some preprocessing steps:

train.dtypes

C12       object
C13       object
C14       Object

train['C14'] = train.C14.astype(int)

train.dtypes

C12       object
C13       object
C14       int32
