How to extract property of pandas index from string

Question

I have a question, How can I extract index property from string variable in pandas? I want to extract particular properties from datetime index in a loop. code attached below:

features_list = ['dayofweek',
             'dayofyear',
             'day',
             'year',
             'month',
             'daysinmonth',
             'is_leap_year',
             'is_month_end',
             'is_quarter_end',
             'is_year_end',
             'is_month_start',
             'is_quarter_start',
             'is_year_start',
             'quarter',
             'week']
for feat from features_list:
    dataset[f'{feat}'] = dataset.index.feat 

so if the value in feat variable is day, the string must be 'dataset.index.day'. if it is week, the string must be 'dataset.index.week'?

Answer 1

Use eval to get from string to property.

dataset[f'{feat}'] = eval("dataset.index."+feat )
