Plutonic Rainbows

Started a new job today. Wrapping up this week's work with Python revision, so here's a simple division calculator using (float(raw_input(">"))) to get user input. I also use \n to create clean lines when terminal gives you the results.

def division(value_1, value_2):
    print "\nDividing %d / %d\n" % (value_1, value_2)
    return value_1 / value_2

value_1 = (float(raw_input(">")))
value_2 = (float(raw_input(">")))

result = division(value_1, value_2)

print "\nThe answer is %d.\n" % (result)

This seems like a lot of code (at least for a beginner like me), but it uses loops and lists so that the user can navigate around with varying outcomes.

from sys import exit

def money_room():
    print "There's plenty of money here. How much do you take?"

    next = raw_input("> ")
    if "0" in next or "1" in next:
        how_much = int(next)
    else:
        dead("Please type in something useful.")

    if how_much < 50:
        print "Nice. You're not greedy. You win!"
        exit(0)
    else:
        dead("You are greedy. You lose.")

def guard_room():
    print "There is a guard here."
    print "The guard has a magazine and is reading it."
    print "The guard is stood in front of a door."
    print "How are you going to get rid of the guard?"
    guard_moved = False

    while True:
        next = raw_input("> ")

        if next == "take magazine":
            dead("The guard takes out his gun and you're toast.")
        elif next == "distract guard" and not guard_moved:
            print "The guard has moved from the door.
            You can go through it now."
            guard_moved = True
        elif next == "distract guard" and guard_moved:
            dead("The guard gets annoyed and pulls out a gun.
            You know how this ends.")
        elif next == "open door" and guard_moved:
            money_room()
        else:
            print "I have no idea what that means."

def insanity_room():
    print "What is this place?"
    print "It is the room of insanity."
    print "Do you run for your life or simply bash your head against the wall."

    next = raw_input("> ")

    if "run" in next:
        start()
    elif "head" in next:
        dead("Well, that's the end of you.")
    elif "bash" in next:
        dead("Well, that's the end of you.")
    else:
        insanity_room()

def dead(why):
    print why, "Good Job!"
    exit(0)

def start():
    print "You are in a dark room."
    print "There is a door to right and left."
    print "Which one do you take?"

    next = raw_input("> ")

    if next == "left":
        guard_room()
    elif next == "right":
        insanity_room()
    else:
        dead("You stumble around the room until you are dead.")

start()

while loops are a good deal more difficult as you have to visualise what is actually happening. One condition will keep running potentially forever until that condition is no longer met. The script below appends numbers to a list and stops doing so when the value is equal to or greater than 6.

i = 0

numbers = []

while i < 7:
    print "The number at the top is now: %d" % i
    numbers.append(i)

    i = i + 1
    print "Numbers are now", numbers
    print "The number at the bottom is now: %d" % i

print "The numbers:"

for num in numbers:
    print num

I have found loops and lists quite difficult to follow so I've broken it down to something more simple; along with comments.

On the weather, most of the snow is melting quickly now as the temperatures move into positive figures.

#build an empty list 

elements = []

#add numbers in the range 1-10 and append them to elements

for n in range(1, 11):
    print "Adding %d to the list." % n
    elements.append(n)

#loop through the list and print the numbers    

for n in elements:
    print "These are the numbers: %d" % n
