In python/SpyderA. We can define the sum from 1 to x (i. e. 1 + 2 + ... + x) recursively as follows for integer x ≥ 1:1, if x = 1x + sum from 1 to x-1 if x > 1Complete the following Python program to compute the sum 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 recursively:def main():# compute and print 1 + 2 + ... + 10print (sum(10) )def sum(x):# you complete this function recursivelymain()}B. Simple ATM simulation – write an application that displays a menu of options and process accordingly based on user selection. Implement a function for each option selected. Add exception handling where appropriate.
