Sometimes, while working with Python list, we can have a problem in which we have to group strings in a way that at occurrence of particular element, the string list is grouped. This can be a potential problem of day-day programming. Let’s discuss certain way in which this problem can be performed.
Method : Using
groupby() + list comprehension + lambda
This task can be performed using combination of above functions. In this, we group the elements using groupby() and decision of grouping element logic is done in form of lambda function.
The original list is : ['gfg', 'is', 'best', 'and', 'is', 'popular'] Resultant list after grouping : [['gfg'], ['best', 'and'], ['popular']]
