Dictionaries in Python are used to store data in key-value pairs. A dictionary is an unordered collection of key-value pairs where keys must be unique, but values can be duplicated. Dictionaries are written with curly brackets and contain keys and values separated by colons. Items in a dictionary can be accessed, added, or removed using their key.

2. DICTIONARY
• Dictionaries are used to store data values in
key:value pairs.
• A dictionary is a collection which is ordered*,
changeable and does not allow duplicates.
• Dictionaries are written with curly brackets,
and have keys and values:

3. Create and print a dictionary:
• thisdict = {
"brand": "Ford",
"model": "Mustang",
"year": 1964
}
print(thisdict)

4. Dictionary Items
• thisdict = {
"brand": "Ford",
"model": "Mustang",
"year": 1964
}
print(thisdict["brand"])

5. Duplicates Not Allowed
• thisdict = {
"brand": "Ford",
"model": "Mustang",
"year": 1964,
"year": 2020
}
print(thisdict)

6. Accessing Items
 thisdict = {
 "brand": "Ford",
 "model": "Mustang",
 "year": 1964
 }
 x = thisdict["model"]
 Another way using get method
 x = thisdict.get("model")

7. Get all keys
 thisdict = {
 "brand": "Ford",
 "model": "Mustang",
 "year": 1964
 }
 x = thisdict.keys()
 print(x)

8. Get all values
 thisdict = {
 "brand": "Ford",
 "model": "Mustang",
 "year": 1964
 }
 x = thisdict.values()
 print(x)
