CP5805 Practical 1 - double-click and type your name here
Once you've completed these tasks, name your file as Lastname_Firstname_prac_1.ipynb and submit on LearnJCU. E.g., if your name is Alice Smith, your file should be called Smith_Alice_prac_1.ipyn
Task 1
In the code box below, write Python variable definitions for:
· two variables that would be valid and well-named (we have done the first one for you)
· two variables that would be valid, but not well-named
Then write a comment that gives the rule for valid variable names in Python.
In [ ]: first_name = "Guido"
​
Task 2
Consider the following problem description:
A doctor needs to be able to calculate the total amount of a drug that has been administered to a patient. The system will get the hourly dosage from the user, as well as the number of hours they have been receiving the medicine. The system will then display the total for the doctor.
Based on this description think about what variables you will need to receive as input, and display as output.
Then design a solution in pseudocode in the comments below, then implement your solution in Python.

Task 3
Alice is trying to make money trading a new cryptocu
ency, Pythcoin. She has set the following rules for herself:
· if the price of Pythcoin is 70.7 or higher, she sells
· if the price of Pythcoin is 44.4 or lower, she buys - but only if her bank balance is $3000 or more
· otherwise, she neither buys nor sells (sometimes known as HODLing)
Based on Alice's trading strategy above, design and implement a program that asks the user for their bank balance, and then the cu
ent price of Pythcoin. The program should then display either:
· It's time to sell
· It's time to buy
· Keep hodling

# what values should you use to test your code to make sure it works across all the different cases?

Task 4
Test the following code and try and identify any e
ors. (What values should you use for your tests?)
Write what the problems were as a comment below. (Note that here we want a description of the problem, not the solution.)
Then rewrite the code (change it in place) to fix any problems.

age = input("How old: ")
if age < 18:
print("Minor")
elif age > 18:
print("Adult")
