Exercise 6 - Watch List

You are an investor looking to purchase cheap, energy efficient cryptocurrency. You have been given a list of cryptocurrencies and their exchange rates (in the variable exchangeRates), which you must parse to determine which currency to purchase.

The two rules that both must be satisfied before purchasing are:

• cryptocurrency must be exchanging below $1.50AUD
• cryptocurrency must be on the watch list for energy efficient crypto currency

The data for this task has been provided for you below (note - it has been redacted to make completing this task more manageable). The output should look something like this:

The algorithm must parse all of the cryptocurrencies in the exchangeRates variable, and make use of at least two sub-routines (measureCost and checkEnergyEfficiency). It has been started, but needs finishing:

energyEfficientCryptos = [
  "SolarCoin",
  "Chia",
  "Cardano",
  "Stellar",
  "Harmony"
]

exchangeRates = [
  ("Bitcoin", 65460.31),
  ("Ethereum", 5272.41),
  ("Cardano", 1.87),
  ("Stellar", 0.38),
  ("Dogecoin", 0.24),
  ("Ripple", 1.19),
  ("Harmony", 0.34)
]

BEGIN checkEnergyEfficiency(cryptocurrency)
  ...
END

BEGIN measureCost(cryptocurrency, exchangeRate)
  ...
END

BEGIN
  ...
END

Code the measureCost and checkEnergyEfficiency modules you have planned above in Python:

energyEfficientCryptos = [
  "SolarCoin",
  "Chia",
  "Cardano",
  "Stellar",
  "Harmony"
]

exchangeRates = [
  ("Bitcoin", 65460.31),
  ("Ethereum", 5272.41),
  ("Cardano", 1.87),
  ("Stellar", 0.38),
  ("Dogecoin", 0.24),
  ("Ripple", 1.19),
  ("Harmony", 0.34)
]

def checkEnergyEfficiency(cryptocurrency):
  #checkEnergyEfficiency() module code here

def measureCost(cryptocurrency, exchangeRate):
  #measureCost() module code here

#MAIN ALGORITHM:
for (crypto, cost) in exchangeRates:
  print("Checking", crypto)
  costEffective = measureCost(crypto, cost)
  energyEfficient = checkEnergyEfficiency(crypto)
  
  if costEffective and energyEfficient:
    #...
