Unit 1: ARTIFICIAL INTELLIGENCE
What is Artificial intelligence?
python dictionary
A dictionary is an unordered and changeable sequence datatype that stores mappings of unique keys to values. Dictionary does not allow duplicates. Dictionaries elements are stored within curly brackets ({}), including key-value pairs separated by commas (,). In a dictionary, you can add, change or remove elements, also you can loop, copy and nest a dictionary.
PROGRAM EXAMPLES

# a python
program to display the position number (key) and reward (value) # using
dictionary position = { 1 : "Gold", 2 : "Silver", 3 : "Bronze" } print(position)
#display the 2
value of the dictionary print(position[2]) #output: Silver |
Lab2

# a python
program to display the position number (key) and reward and cash prize
(values) # using
dictionary position_data
= { 1 : "Gold, #500000", 2 : "Silver, #250000", 3 : "Bronze, #125000" } print(position_data) #output: {1:
'Gold, #500000', 2: 'Silver, #250000', 3: 'Bronze, #125000'}
#display the 1
value of the dictionary print(position_data[1]) #output: Gold, #500000
#display the
keys of the dictionary print(position_data.keys()) #output: dict_keys([1, 2, 3])
#alternatively mykey =
position_data.keys() print(mykey)
#display the
length of the dictionary print(len(position_data)) #output: 3
#display the
datatype of the dictionary print(type(position_data)) #output: <class 'dict'>

# a python program
to display the country name (key) and capital (value) # using
dictionary
country = { "Nigeria" : "Abuja", "Ghana" : "Accra", "South Africa" :
"Pretoria" }
print(country)
#display the
South Africa value of the dictionary print(country["South
Africa"]) #output: Pretoria
#display a new
view of the dictionary print(country.items()) #output: Pretoria
#display the
first N key-value pairs and above y = list(country.items())[:1] # test 0, 1, 2 print(y) #output:
[('Nigeria', 'Abuja')] |

# a python
program to display the continent (key) # total
countries in each continent (value) # using dictionary
continent_data
= { "Asia" : 48, "Africa" : 54, "Antarctica" : 0, "Australia" : 6, "Europe" : 50, "North America" : 23, "South America" : 12 }
print(continent_data) |

# a country in
each continent # a python
program to display the country name (key) # country
features such as capital, GDP (as at 2021), population, ethnic groups
(values) # using
dictionary # storing list
inside a dictionary
country_data =
{ "India" : "New Delhi,
3.176 trillion USD (2021), 1.408 billion, 2000+", "Nigeria" : "Abuja, 440.8
billion USD, 213.4 million, 250+",
"Research_Station_In_Antarctica" : "Maitri and Dakshin
Gangotri", "Austrialia" : "Canberra,
1.553 trillion USD, 25.69 million , 270+", "United_Kingdom" :
"London, 3.131 trillion USD, 67.33 million, 19", "USA" : "Washington DC,
23.32 trillion USD, 450 million, 6", "Brazil" : "BrasÃlia,
1.609 trillion USD, 214.3 million, 305+ ", "independence_year": [1947,
1960, "", 1901, 1776, 1776,
1822] }

# a python
program to display my details # using dictionary # search and
print matching key-value pairs # concepts
applied: for loop statement to iterate, # if
statememnt to check condition #str python
datatype to convert dict datatype of value to string
myDetails = { "Name" : "Ajala
Theophilus", "Favourite_color" :
"Blue", "Youtube_handle" :
"dmactutor", "Website" :
"whitepaceblog.blogspot.com", "Age" : 18, "Area_of_interest" : "Data
science, Machine Learning, Web Application, Mobile Application" } # display all
dictionary elements print(myDetails)
# print
key-value pair that meets the condition of value starting with "dm" # indentation
is very important to adhere to in python when using 'for' and 'if' keywords for mykey,
myvalue in myDetails.items(): if str(myvalue).startswith('dm'): print(mykey, myvalue) #Output: Youtube_handle
