8#to print data you do print(name_of_dictionary['key_name'])

10print(student_data['name']) # will print 'inderpaal'
11print(student_data['age']) # will print 21
12print(student_data['course'])[0]
13#this will print 'Bsc' since that field is an array and array[0] is 'Bsc'

1# Dictionaries in Python are used to store set of data like Key: Value pair

3# the syntax of a dictionary in Python is very simple we use {} inside that
4	# we define {Key: Value}, to separate multiple values we use','
