Example 3: enumerate

categorical_features_new=[features for features in df.columns if df[features].dtypes=='object']
for feature in categorical_features_new:
    labels_sorted=df[feature].value_counts().sort_values().index
   
    labels_ordered={k:i for i,k in enumerate(labels_sorted,0)}
    
    df[feature]=df[feature].map(labels_ordered)
