Sort the list, ist (use the list sort method). Submit History: (10 of 10) 03/13/21 01:57:16 1st-[1,2,3,4] 1st.sort() print(1st) Given a dictionary d and a list ist, remove all elements from the dictionary whose key is an element of lst. For example, given the dictionary (1:2, 3:4, 5:6, 7:8) and the list [1, 7), the resulting dictionary would be (3:4, 5:6). Assume every element of the list is a key in the dictionary. Instructor Notes: CORRECTION: Do not assume that all the entries in the List 1st are keys in the Dictionary a Submit History: (14 of 14) 03/13/21 01:48:37 1st (1 dict={1:2,3:4,5:6,7:8} 3. for i in 1st: del dict() 4 6
