Split a string in equal parts (grouper in Python)
Grouper recipe is an extended toolset made using an existing
itertool as building blocks. It collects data into fixed-length chunks or blocks.
Existing Itertools Used:
izip_longest(*iterables[, fillvalue]) : Make an iterator that aggregates elements from each of the iterables. If the iterables are of uneven length, missing values are filled-in with fillvalue. Iteration continues until the longest iterable is exhausted.
- The extended tools offer the same high performance as the underlying toolset.
- The superior memory performance is kept by processing elements one at a time rather than bringing the whole iterable into memory all at once.
- Code volume is kept small by linking the tools together in a functional style which helps eliminate temporary variables.
- High speed is retained by preferring “vectorized” building blocks over the use of for-loops and generators which incur interpreter overhead.
Input : str = ABCDEFG, l = 3 Output : ABC DEF Gxx Explanation: Grouping characters of string in set of 3: ABC DEF Gxx. 'x' is added to the set which doesn't have 3 elements in it. Input : str = GEEKSFORGEEKS, l = 5 Output : GEEKS FORGE EKSxx
Below is the Python3 code :
ABC DEF Gxx
