When we print values in a dictionary, is there any default sorting that use to print the keys and values in a Python dictionary? Or do they randomly print the key , value pairs?
Please see below code. is there any order of dictionary value print in python?
confusion = {}
confusion[1] = 1
confusion[4] = 22
confusion['5'] = 2
confusion['2'] = 2
confusion[1.0] = 4
confusion['1'] = 2
print confusion
The result is {'2': 2, 1: 4, '1': 2, '5': 2, 4: 22}
Use collections.OrderedDict if you want to have the insertion order maintained. By default, python's dict does not maintain the order.
No, dictionaries are by definition unordered. What you see here might change from version to version and platform to platform
Quoting the documentation:
CPython implementation detail: Keys and values are listed in an arbitrary order which is non-random, varies across Python implementations, and depends on the dictionary’s history of insertions and deletions.
