Use the correct code in order to return the value associated with key 4. Do not use a method as a solution for this exercise!

crypto = {1: "Bitcoin", 2: "Ethereum", 3: "Cardano", 4: "XRP", 5: "Solana"}


print(value)

Output: Cardano

Use the correct code in order to update the value associated with key 3 to “Polygon”.

crypto = {1: "Bitcoin", 2: "Ethereum", 3: "Cardano", 4: "XRP", 5: "Solana"}


print(crypto[3])

Output: Polygon

Use the correct code to return the number of key-value pairs in the dictionary.

crypto = {1: "Bitcoin", 2: "Ethereum", 3: "Cardano", 4: "XRP", 5: "Solana"}

number = 

print(number) 

Output: 5

Use the correct code to delete the key-value pair associated with key 4. Do not use a method as a solution for this exercise!

crypto = {1: "Bitcoin", 2: "Ethereum", 3: "Cardano", 4: "XRP", 5: "Solana"}


print(crypto) 

Output: {1: "Bitcoin", 2: "Ethereum", 3: "Cardano", 5: "Solana"}

Use the correct code in order to delete the key-value pair associated with key 3. This time, use a method as a solution for this exercise!

crypto = {1: "Bitcoin", 2: "Ethereum", 3: "Cardano", 4: "XRP", 5: "Solana"}



print(crypto) 

Output: {1: "Bitcoin", 2: "Ethereum", 3: "Cardano", 5: "Solana"}

Use the correct code in order to verify that 6 is not a key in the dictionary.

crypto = {1: "Bitcoin", 2: "Ethereum", 3: "Cardano", 4: "XRP", 5: "Solana"}

check = 

print(check) 

Output: True

Use the correct method in order to delete all the elements in the dictionary.

crypto = {1: "Bitcoin", 2: "Ethereum", 3: "Cardano", 4: "XRP", 5: "Solana"}

crypto.

print(crypto) 

Output: {}

Use the correct method in order to get a list of all the values in the dictionary.

crypto = {1: "Bitcoin", 2: "Ethereum", 3: "Cardano", 4: "XRP", 5: "Solana"}

all_list = 

print(list(all_list)) 

Output: ["Bitcoin", "Ethereum", "Cardano", "XRP", "Solana"]
