Please create the following functions with python using for and while loops, thank you.
a) my_sum=1+2+3+4+5+6+7+8+9+10+11+12+13+14+15+ 16 + 17 + 18 + 19 + 20
Write a loop to do the above summation more efficiently
b) my_list=[9,8,7,6,5,4,3,2,1]
Write a loop to print out each element in the list on a new line
c) x=1 y=2
____________________ z=x+y
x=y
y=z
Write a line of code on the blank line that will create a loop that will end when y is greater than 100
