Python Scripting from Early Ages of my Career.

I had to piece together some old data from some of my various Python Projects. I came accross this gem.

# Charles Goodling

# Assignment 7

# This program will ask a user for two inputs. First input will be the base number then the second
# will be the exponent or power the user would like the calculator to solve. This calculator works
# for negatives and positive bases and powers.
# For Example, User inputs 2 for Base and 2 for Power. The calculator outputs 4.

# I tried to make sure I covered all posible inputs and answers. I like to code and it makes things
# more challenging to do more than requested. So I apologize if I went above the requirements.

Below we are creating the recursive statement to do the math for us. We are calling Base and Power from the main function where the user Inputs the numbers.

def pow(base, power):
    
    # Below the function will check if the base is greater then -1 due to having both positive and negative
    # numbers.
    
    if base > -1:

        # Below the function is checking the powers whether 0 or 1+.
        # Any positive number to the 0 power will be 1.
        if power == 0:
            return 1
        
        #  Below is checking to see if the power is negative and then conducting math to give us
        # proper math input because powers can definitely be negative.
        if power < -1:
            return 1 / pow(base, -power)

        # If a power is 1 then the output will be the base. 2^1 would be 2.
        elif power == 1:
            return base
        # Now if the power is positive and above 1 then we will conduct the math giving up our output.
        else :
            return base * pow(base, power - 1)

    # I feel like I could have posibbly made the code shorter but I felt this section was necessary for
    # Negative bases. If a base is negative then the power output for 0 would be -1 rather than 1.
    if base <= -1:
        if power == 0:
            return -1

    # Works the same way as previous but it is meant for negative powers hence the -1. Though a negative
    # base to a negative exponent does not give the same base it will give a decimal.
        if power <= -1:
            return -1 / pow(base, -power)
        elif power == 1:
            return base
        else :
            return base * pow(base, power - 1)

Test the input given. Will not accept decimals nor letters.

def determineBase():
        while True:
            try:
                base = int(input ('Please Enter A Base: '))
            except ValueError:
                print("Please use numbers only. No letters nor decimals.")
                continue
            else:
                return base
# Same as above just to test the Power given.
def determinePower():

        while True:
            try:
                power = int(input ('Please Enter A Power: '))
            except ValueError:
                print("Please use numbers only. No letters nor decimals.")
                continue
            else:
                return power

Piece it all together.

def main():

    #Declares base as the above function.
    base = determineBase()
    #Declares the power as the above function.
    power = determinePower()
    # Runs the above function calling base and power
    pow(base, power)
    # prints both inputs and the answer.
    print("The answer to",base,"to the power of", power,"is", pow(base,power),".")
main()

Here goes another pretty nifty little script I did ages ago for a school project.

# Write a function named determineStatus() that prompts the user for how many
# credits they have earned and uses a decision structure (if, else, etc.) to
# determine the class standing of the student. The function should display the
# standing to the student (90 points).

def determineStatus():
    userInput = eval(input("How many credit hours do you have? "))
    hours = userInput
    F=30
    J=60
    S=90
    Max=200
    if hours <= Max:
      if hours < 0 :
        print("You can't have negative credit hours")
      if 0 <= hours < F:
        print("You are classified as a Freshman")
      if hours >= F and hours < J:
        print("You are classified as a Sophmore")
      if hours >= J and hours < S:
        print("You are classified as a Junior")
      if hours >= S and hours < Max:
        print("You are classified as a Senior")
      if hours >= 200:
        print("With",hours," hours you are either an Alumni, 2nd Degree seeking student or lying about your hours.")
    
# Write a main() function that calls the determineStatus() function (5 points).



def main():
  determineStatus() # Call to determineStatus() function
  
    
main()# Call to main function

I’ve decided to drop this in a Github Repo where I’ll slowly start tossing some random python code that I have as I dig things out of my archive.
