encoder python code example

Example 1: label encoding

from sklearn.preprocessing import LabelEncoder

le = LabelEncoder()
companydata.ShelveLoc = le.fit_transform(companydata.ShelveLoc)

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)

Example 4: .encode python

string = 'pythön!'

print('The string is:', string)

string_utf = string.encode("utf-8")

print('The encoded version is:', string_utf)

# Output:
The string is: pythön!
The encoded version is: b'pyth\xc3\xb6n!'
