Python: Insert an element at the beginning of a given OrderedDictionary

Python Collections: Exercise-22 with Solution

Write a Python program to insert an element at the beginning of a given OrderedDictionary.

Sample Solution:

Python Code:

from collections import OrderedDict
color_orderdict = OrderedDict([('color1', 'Red'), ('color2', 'Green'), ('color3', 'Blue')]) 
print("Original OrderedDict:")
print(color_orderdict)
print("Insert an element at the beginning of the said OrderedDict:")
color_orderdict.update({'color4':'Orange'})
color_orderdict.move_to_end('color4', last = False)
print("\nUpdated OrderedDict:")
print(color_orderdict)

Sample Output:

Original OrderedDict:
OrderedDict([('color1', 'Red'), ('color2', 'Green'), ('color3', 'Blue')])
Insert an element at the beginning of the said OrderedDict:

Updated OrderedDict:
OrderedDict([('color4', 'Orange'), ('color1', 'Red'), ('color2', 'Green'), ('color3', 'Blue')])

Python: Tips of the Day

Use Reversed() In for Loops:

>>> tasks = ['laundry', 'picking up kids', 'gardening', 'cooking']
>>> for task in reversed(tasks):
...     print(task)
... 
cooking
gardening
picking up kids
laundry
