Ethereum vs Bitcoin differences in Blockchain / Solidity - Hands-On Comparison

Ethereum vs Bitcoin Differences

📖 Scenario: You are learning about two popular cryptocurrencies: Ethereum and Bitcoin. Each has unique features and differences. You want to organize their key differences in a Python dictionary to compare them easily.

🎯 Goal: Create a Python program that stores Ethereum and Bitcoin differences in a dictionary, filters the differences based on importance, and prints the filtered results.

📋 What You'll Learn

Create a dictionary called crypto_diff with exact keys and values for Ethereum and Bitcoin differences

Create a variable called importance_threshold with the value 3

Use a dictionary comprehension to create a new dictionary called important_diff that includes only differences with importance greater than or equal to importance_threshold

Print the important_diff dictionary

💡 Why This Matters

🌍 Real World

Organizing and comparing features of cryptocurrencies helps investors and developers understand their strengths and weaknesses.

💼 Career

Data filtering and dictionary comprehension are common tasks in data analysis and software development roles.

1

Create the differences dictionary

Create a dictionary called crypto_diff with these exact entries: 'Ethereum': {'Smart Contracts': 5, 'Consensus': 4, 'Supply Limit': 2} and 'Bitcoin': {'Smart Contracts': 1, 'Consensus': 5, 'Supply Limit': 5}

Blockchain / Solidity

# Create the crypto_diff dictionary with Ethereum and Bitcoin differences
# Your code here

Need a hint?

Use a dictionary with keys 'Ethereum' and 'Bitcoin'. Each key maps to another dictionary with the exact keys and values.

2

Set the importance threshold

Create a variable called importance_threshold and set it to 3

Blockchain / Solidity

crypto_diff = {
    'Ethereum': {'Smart Contracts': 5, 'Consensus': 4, 'Supply Limit': 2},
    'Bitcoin': {'Smart Contracts': 1, 'Consensus': 5, 'Supply Limit': 5}
}
# Create importance_threshold variable and set it to 3
# Your code here

Need a hint?

Just assign the number 3 to the variable named importance_threshold.

3

Filter important differences

Use a dictionary comprehension to create a new dictionary called important_diff that includes only the differences with importance greater than or equal to importance_threshold. Iterate over crypto_diff.items() and filter inner dictionary items accordingly.

Blockchain / Solidity

crypto_diff = {
    'Ethereum': {'Smart Contracts': 5, 'Consensus': 4, 'Supply Limit': 2},
    'Bitcoin': {'Smart Contracts': 1, 'Consensus': 5, 'Supply Limit': 5}
}
importance_threshold = 3
# Create important_diff dictionary using dictionary comprehension
# Your code here

Need a hint?

Use nested dictionary comprehension: outer for coin, diffs in crypto_diff.items(), inner for key, val in diffs.items() with condition val >= importance_threshold.

4

Print the filtered differences

Write print(important_diff) to display the filtered dictionary of important differences.

Blockchain / Solidity

crypto_diff = {
    'Ethereum': {'Smart Contracts': 5, 'Consensus': 4, 'Supply Limit': 2},
    'Bitcoin': {'Smart Contracts': 1, 'Consensus': 5, 'Supply Limit': 5}
}
importance_threshold = 3
important_diff = {
    coin: {key: val for key, val in diffs.items() if val >= importance_threshold}
    for coin, diffs in crypto_diff.items()
}
# Print the important_diff dictionary
# Your code here

Need a hint?

Use the print function to show the important_diff dictionary.
