Test preparation for P1 While: Repeats instructions (body) while condition is True Stops when condition becomes False Else statement (optional) executed after loop ends Ex: 1. Nr of digits of a nr: a = 123 c=1 while a > 9: a = a // 10 c=c+1 else: print("Finishe...
Test preparation for P1 While: Repeats instructions (body) while condition is True Stops when condition becomes False Else statement (optional) executed after loop ends Ex: 1. Nr of digits of a nr: a = 123 c=1 while a > 9: a = a // 10 c=c+1 else: print("Finished: ", c, "digits") 2. Write a program that reads an integer number from standard input and computes the sum of its digits. a=int(input()) sum = 0 while a > 0: sum = sum + a % 10 a = a // 10 else: print(sum) 3. Write a program that reads an integer number from standard input and computes the product of its digits. a=257 p=1 while a>0: p=p*(a%10) a=a//10 else: print(p) 4. Write a program that reads a number, N, from standard input and computes the sum of the first N natural numbers (N included). N=int(input()) sum=0 i=1 while i
