Is there a way to reference questions that are structured the same in for loop?

I want to call on a list of questions that are structured the same way (e.g. E1_1, E1_2, E1_3, etc.) in a for loop

Example:

list_of_questions = ['E1', 'E2', 'E3'] # each question in list has associated questions 'E1_1', 'E1_2', 'E1_3', 'E2_1', 'E2_2', 'E2_3', etc.

for question in list_of_questions:
   for i in range(1,3):
      df['E1_i'] = df['E1_i'] == 1

I know this can be done in Stata via `i' syntax, but I'm wondering if the same can be done in Python.

Thanks!
