'Rohan'
>>> next(myiterator)
'Sohan'
>>> next(myiterator)
'Sita'
>>>

Example 2

>>> web="salesforcedrillers"
>>> myiter=iter(web)
>>> next(myiter)
's'
>>> next(myiter)
'a'
>>> next(myiter)
'l'
>>> next(myiter)
'e'
>>> next(myiter)
's'
>>> next(myiter)
'f'
>>> next(myiter)
'o'
>>>

Example 3

value = "salesforcedrillers"
myobj= iter(value) 
  
while True: 
    try:  
        printing = next(myobj) 
        print(printing,end=",")
