OLA 5: Collatz Sequence Function 12 17 34 Due: Fri Oct 19, 2018 by 11:59 PM-may be tumed in until Oct 26 by 1159 PM with reduced points (per Open Lab- Project guidance found in the course syllabus) Assignment id: ola5 Assignment type: Project Required Files: ola5.py, myout.log Lab description: In this you will explore the Collatz mathematical sequence. This sequence eventually converges to the value 1, regardless of the initial input Requirements: 1. Write a function named collatz0 that has one parameter named number. If number is . even, then collatz0) should print number //2 and retum this value (integer divison). . odd, then collatz) should print and retum 3 number + 1 2. Write a program that lets the user type in an integer, and keeps calling the collatz() function on subsequent results until the function returns the value 1 Hints: . You must use a loop that exits the program only when the returned value is 1 . Remember to convert the returm value from input() to an integer with the int() function otherwise, it will be a string value. An integer number is even if number % 2 1+0, and it's odd if number % 2 : . 1. A sample output of the program should look something like this: Enter number: 3 10 16

Answer 1

Code:

def collatz(num):   
if ( num %2 ==0 ) :#if number is even below calculation proceed
Number=num//2 #num value in with divied by two and assign new number variable
print(Number);#print value
if Number!=1:#if Number is not equal to 1
collatz(Number);#function are called
else:
return (Number)#else return number
elif (num % 2 == 1) : #else number is odd below calculation proceed
Number=3*num+1 #num value in with add one and multy by three and assign new number variable
print (Number)#print value
collatz(Number)#function are called
return Number;#return number

#user input and validation while loop
while True:
try:
num = int(input("Enter number:")) #user input and store value in num  
except ValueError:
print("Enter a valid integer")
continue
else:
if num < 1:#condition check
print("enter a valid positive integer")
continue
break

collatz(num)

null
