how to use label encoding in python code example

Example 1: label encoding

Example 2: how to use label encoding in python

obj_df["body_style"] = obj_df["body_style"].astype('category')
obj_df.dtypes

obj_df["body_style_cat"] = obj_df["body_style"].cat.codes
obj_df.head()

Example 3: transform categorical variables python

from sklearn.preprocessing import LabelEncoder

lb_make = LabelEncoder()
obj_df["make_code"] = lb_make.fit_transform(obj_df["make"])
obj_df[["make", "make_code"]].head(11)
