Question

convert the while loop into for loop

x = int(input('Enter initial value: '))

count = 0 if(x<1):

print('Error')

exit()

print('Initial value is: ',x,' ',end='')

while(x!=1):

if(x%2==0):

x=x/2

else:

x=3*x+1

count+=1

if(x!=1):

rint('Next value is: ',int(x),' ',end='')

else: print('Final value ',int(x),', ',end='')

print('number of operations performed ',int(count),' ',end='')

break

Answer 1

x = int(input('Enter initial value: '))

count = 0
if x < 1:
    print('Error')
    exit()
print('Initial value is: ', x, ' ', end='')

# this does not have number of iterations already defined.
# so, it's never a good idea to use a for loop in this scenario
# anyway I am going to change this to a for loop
for i in range(100000):
    if x % 2 == 0:
        x = x / 2
    else:
        x = 3 * x + 1
    count += 1
    if x != 1:
        print('Next value is: ', int(x), ' ', end='')
    else:
        print('Final value ', int(x), ', ', end='')
        print('number of operations performed ', int(count), ' ', end='')
        break
