Dict Example in Python

Today, we discuss about the Dict concept in Python.

Dict in Python consists of Key & Value pairs. This is similar to Hash concept in Perl language.

Keys are unique in Dict, Values are not necessarily unique in nature.

Let's discuss with an example, let's dive & have fun :


relatives = {"Lisa" : "daughter", "Bart" : "son", "Marge" : "mother", "Homer" : "father", "Santa" : "dog"}


#raw_input(), print for Python 2.X Version 
#input(), print() for Python 3.X Version


#Keys are unique

relatives['Marge'] = "mother";
relatives['marge'] = "mother1";

#'Marge' and 'marge' are different keys

for member in sorted(relatives.keys()):
    print("\n",member, "=>", relatives[member])
#print "\n",member

for member in sorted(relatives.values()):
    print("\n",member)
#print "\n",member

for key, value in relatives.items():
print("\n", key, "=>", value)
#print "\n", key, "=>", value
