How to read weekdays from a csv file and make a compresion in python?

Question

My code is following like this:

import csv
from datetime import datetime
get_time=lambda x:datetime.strptime(x, '%A').strftime('%A')

with open('days.csv') as f:
   d1=[get_time(row[0]) for row in csv.reader(f)]

for n in d1
  if n== Saturday or Sunday (how to show it in python??)
    print('yes')
 else:
   print('no')

Can someone help me to show if n == Saturday or Synday in python!
