Filter Consecutive Elements in Tuples using Python

When it is required to filter consecutive elements from a list of tuple, a method is defined that takes a list of tuple as a parameter and checks the index of every tuple, and returns a Boolean value depending on the index.

Example

Below is a demonstration of the same −

print("Method definition begins...")
def check_consec_tuple_elem(my_tuple):
   for idx in range(len(my_tuple) - 1):
      if my_tuple[idx + 1] != my_tuple[idx] + 1:
         return False
   return True
print("Method definition ends...")
my_tuple = [(23, 24, 25, 26), (65, 66, 78, 29), (11, 28, 39), (60, 61, 62, 63)]

print("The list of tuple is : " )
print(my_tuple)

my_result = []

for elem in my_tuple:
   if check_consec_tuple_elem(elem):
      my_result.append(elem)

print("The resultant tuple is : ")
print(my_result)

Output

Method definition begins...
Method definition ends...
The list of tuple is :
[(23, 24, 25, 26), (65, 66, 78, 29), (11, 28, 39), (60, 61, 62, 63)]
The resultant tuple is :
[(23, 24, 25, 26), (60, 61, 62, 63)]

Explanation

• A method named ‘check_consec_tuple_elem’ is defined that takes a tuple as a parameter.

• It iterates through the tuple and checks to see if element at an index and the element at the same index incremented by 1 are equal.

• If not, it returns False.

• Outside the method, a list of tuple is defined and is displayed on the console.

• An empty list is defined.

• The list of tuple is iterated over, and the method is called by passing every tuple to it.

• The result of this is appended to the empty list.

• This list is displayed as the output on the console.
