#the keys are the left hand side and the values are the right hand side
#to print data you do print(name_of_dictionary['key_name'])
print(student_data['name']) # will print 'inderpaal'
print(student_data['age']) # will print 21
print(student_data['course'])[0]
#this will print 'Bsc' since that field is an array and array[0] is 'Bsc'dictionary in python
# Dictionaries in Python are used to store set of data like Key: Value pair
# the syntax of a dictionary in Python is very simple we use {} inside that
# we define {Key: Value}, to separate multiple values we use','

"Loop": "The action of doing sommething again and again",
}
# to retrieve the values from a dictionary we use the Key name as an Index
# retrieving the Function's definition
print(programming_dictionary["Function"]) # this will print the definition of Function
# if you wanna print all the entries in the dictionary you can do that by for loop

# the following code will add another entry to the dictionary called Variable

# For a good format:
for i in dictionary:
print(i, ":")
for j in dictionary[i]:
print(" ", j, ":", dictionary[i][j])
print()
# Output:
Jeff :
lastname : bobson
age : 55
working : True
James :
lastname : Bobson
age : 34
working : False
# For just a quick reading:
for k, v in dictionary.items():
print(k, v)
# Output:
Jeff {'lastname': 'bobson', 'age': 55, 'working': True}
James {'lastname': 'Bobson', 'age': 34, 'working': False}Copyright © 2021 Codeinu
