Question

As you should recal in this class, there were several phases of groups throughout the semester. At times, two people in the class would end up in a group with a person who was in their group in the previous phase! In this problem, you should implement a function that could be used to help check that that doesn't happen. Write a program namesfind valid groups. This is a function that should take three parameter variables. The first parameter is a string, with the name of a person to find valid groups for. Call this person The second parameter that is a list of strings, which should contain the three people who were in s group previously. The third is a 2-dimensional list, which represents all of the 4-person groups in a class for the next phase. The program should print out all of the groups that are valid for the user to be placed in. A valid group is any group that does not have one of the three people listed in the second parameter in it.You may not use the t For example roster C''b'd'] 13. previous-C'e, a, 'h Find validgroupsC"r". previous, roster) Should print: Group 3 Group 4 Group And roster a',b'e' 5'1 previous-('t'· 's. ] find.valid groupsć's',previous, roster)

Answer 1

def find_valid_groups(a,previous,roster):
   i=1
   for row in roster:
       flag=0
       for item in row:
           if item==previous[0] or item==previous[1] or item==previous[2]:
               flag=1
       if flag==0:
           print("Group",i)
       i=i+1      

roster= [['a','b','c','d'],
['e','f','g','h'],
['i','j','k','l'],
['m','n','o','p'],
['t','u','v','w']]
previous = ['e','a','h']
find_valid_groups('r',previous,roster)          

def find_valid_groups (a,previous,roster): 1 for row in roster: flag-0 for item in row: 4 if item previous [0] or item-previous [1] or item -previous [2]: flag-1 if flag-0: print("Group",i) 10 i-i+1 12 roster[['a, 'b','c,'d', 17 previous ['e,'a','h' 18 find_valid_groups 'r,previous, roster) 19
