How do you create a dictionary which can preserve the order of pairs?Answer: We know that regular Python dictionaries iterate over pairs in an arbitrary order, hence they do not preserve the insertion order of pairs.Python 2.7. introduced a new “OrderDict” class in the “collections” module and it provides the same interface like the general dictionaries but it traverses through keys and values in an ordered manner depending on when a key was first inserted.Eg: from collections import OrderedDictd = OrderDict([(‘Company-id’:1),(‘Company-Name’:’Intellipaat’)])d.items() # displays the output as: [(‘Company-id’:1),(‘Company-Name’:’Intellipaat’)].

Python Interview Questions and Answers are presenting you to the frequently-posted questions in Python interviews. Sign up GitHub is where the world builds software 26. They support (fairly) efficient insertion, deletion, appending, and concatenation, and Python’s list comprehensions make them easy to construct and manipulate.They have certain limitations: they don’t support “vectorized” operations like elementwise addition and multiplication, and the fact that they can contain objects of differing types mean that Python must store type information for every element, and must execute type dispatching code when operating on each element.NumPy is not just more efficient; it is also more convenient.
