Python | Split tuple into groups of n

Given a tuple, the task is to divide it into smaller groups of n. Let’s discuss a few methods to accomplish a given task.

Method #1: Using enumerate and range function

# Python code to demonstrate
# how to split tuple
# into the group of k-tuples
  
# initialising tuple
ini_tuple = (1, 2, 3, 4, 8, 12, 3, 34,
             67, 45, 1, 1, 43, 65, 9, 10)
  
# printing initial tuple
print ("initial list", str(ini_tuple))
  
# code to group
# tuple into size 4 tuples
res = tuple(ini_tuple[x:x + 4
      for x in range(0, len(ini_tuple), 4))
  
# printing result
print ("resultant tuples", str(res))

Output:

initial list (1, 2, 3, 4, 8, 12, 3, 34, 67, 45, 1, 1, 43, 65, 9, 10)
resultant tuples ((1, 2, 3, 4), (8, 12, 3, 34), (67, 45, 1, 1), (43, 65, 9, 10))

    return zip(*args)
