Python Collections: Exercise-22 with Solution

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

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')])

Unzipping:

name = 'abcdef'
suffix = [1,2,3,4,5,6]
result = zip(name, suffix)
--> returns (a,1),(b,2),(c,3),(d,4),(e,5),(f,6)
unzipped = zip(*result)
