The elements of a list are immutable.
Select one:
True
False

1. False
A data type in which the values are made up of components, or elements, that are themselves values is known as an Collection data type
2. a. Tricotomy
3. a. -1
The above code returns the index of the character that is passed as second parameter in string passed as first parameter if it is not found after looping through entire array it will return -1
4. a. 24
The above code returns the index of character passed to the function in the string.
5. a True
6. a. 5 5 5.000000
first string, integer and float
7. b. False
Multiple variables containing reference to same object is known as aliases where as to create a new object having same value as existing object is known as clone
8.a. 14
In the above program mylist is a 2-dimensional matrix
and a iterates through rows and b iterates through columns but b runs only till 1 since given b<2
so the total is the sum of first 2 elemnts of each row
total = mylist[0][0]+mylist[0][1]+mylist[1][0]+mylist[1][1]+mylist[2][0]+mylist[2][1] =2+4+1+2+2+3 = 14
9. b. False
The output is

banana
apple
quince

each element is printed on a new line
10. a. now is the time
As in each loop the value of a is incremented by 2 the values of a will be 0,2,4,6
the strings at those positions are printed\
11. option - (b). a
The indexes start from 0 the value at index 1 is a so a is printed
12. a. True
The types which are comprised of smaller types are known as compound data types
13. a. True
14. a. True
15. b . False
Elements in the list are mutable they can be changed
