Assignment#7 - Mohammed Abdul Wasay

1. Write a python function that returns the index of the smallest element in a list of integers. If the number of such elements is greater than 1, return the smallest index. Use the following function header: def indexOfSmallestElement(lst):

def indexOfSmallestElement(lst): 
    #check if elements is greater than 1
    if len(lst)>1:
          
        #get the minimum value in the list
        smallest_value = min(lst)

        #return the index of minimum value 
        smallestvalue_index=lst.index(smallest_value)
        return smallestvalue_index
    else:
        print("List contains one or no items")
 
if __name__ == "__main__" :
 
    #create and initialize a list
 
    list1 = [23,56,32,89,21,44,51]
 
    min_list1 = indexOfSmallestElement(list1)
 
    print("Index of smallest value is ",min_list1)

Index of smallest value is  4

1. Write the python function mostCommonName, that takes a list of names (such as ["Jane", "Aaron", "Cindy", "Aaron"], and returns the most common name in this list (in this case, "Aaron"). If there is more than one such name, return a set of the most common names. So mostCommonName(["Jane", "Aaron", "Jane", "Cindy", "Aaron"]) returns the set {"Aaron", "Jane"}. If the set is empty, return None. Also, treat names case sensitive, so "Jane" and "JANE" are different names.

# function returns first occurance of most common of names in a list
def most_commons(lst):
    return max(set(lst), key=lst.count)

List = ["Jane", "Aaron", "Cindy","Jane", "Aaron"]
most_commons(List)

'Jane'

# function returns first occurance of most common of names in a list using counter()
from collections import Counter

def Most_Common(lst):
    data = Counter(lst)
    return data.most_common(1)[0][0]

List1 = ["Jane", "Aaron", "Cindy","Jane", "Aaron"]
most_commons(List1)

'Jane'

# function returns occurance of most common of names in a list using counter()
from collections import Counter
def mostCommonNames(lstofnames): 
    mostcomm = {}
    mostcomm = Counter(lstofnames)
    #return mostcomm
    print(mostcomm.most_common(2))

List = ["Jane", "Aaron", "Cindy", "Aaron","Jane"]
mostCommonNames(List)

[('Jane', 2), ('Aaron', 2)]

1. Write the python function isPalindromicList(a) that takes a list and returns True if it is the same forwards as backwards and False otherwise.

def isPalindromicList(a):
   if a == a[::-1]:
      print("The list is a palindrome")
   else:
      print("The list isn't a palindrome")

mylist = [77, 1, 56, 65, 1, 77]

print("The list is :")
print(mylist)

mylist = ' '.join([str(elem) for elem in mylist])
isPalindromicList(mylist)

The list is :
[77, 1, 56, 65, 1, 77]
The list is a palindrome
