For instance, say:
#create two dictionaries
c = {'gaurav':'patel','nilesh':'khan','ramesh':'sawant','anu':'marathe'}
d = {'amit':'waghe','swapnil':'salvi','anish':'mane','raghu':'ranjan'}
#then apply zip
d1 = zip(c,d)
print "D1 goes here"
print d1
The output is :
[('nilesh', 'amit'), ('ramesh', 'raghu'), ('gaurav', 'anish'), ('anu', 'swapnil')]
I do not understand how the pairing works in dictionaries.
In lists, it creates a zipped list with [(a1, b1, c1, ...,n1), ..., (ai, bi, ci, ...., ni),]
How is this decided in for python dictionary?
Dictionaries are not ordered! You will get an unpredictable list of tuples. I guess the same goes for sets.
The reason dictionaries are not ordered is because the keys are internally replaced by hashes in order to make it faster to search through the dictionary. This is also why only hashable objects can be used as keys.
There are ways to make ordered dictionaries. See here:
