Python – Successive element pairing
Sometimes, while working with Python list, we can have a problem in which we need to construct tuples, with the succeeding element, whenever that element matches a particular condition. This can have potential application in day-day programming. Let’s discuss a way in which this task can be performed.
Method : Using
zip() + list comprehension
This task can be performed using the combination of above functionalities. In this, the zip() performs the task of construction of tuples and the catering of condition matching and iteration is handled by list comprehension.
The original list is : [1, 4, 'gfg', 7, 8, 'gfg', 9, 'gfg', 10] Tuple list with desired Successive elements [('gfg', 7), ('gfg', 9), ('gfg', 10)]
