  • Codes and programs

    This page contains codes and little programs I’ve made

    Random numbers

    i = 0
# numNames = ["Zero", "One", "Two", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine", "Ten"]

# Revision:
numNames = "Zero One Two Three Four Five Six Seven Eight Nine Ten".split() # Works exactly the same as the commented code above
numbers = [0,0,0,0,0,0,0,0,0,0,0]

while (i < 10000):
	randNum = round(Random.random() * 10)

	numbers[randNum] += 1

	i += 1

i = 0
total = 0
most = 0
mostRolls = 0
while (i <= 10):
	print(f"{numNames[i]}: {numbers[i]}")
	total += numbers[i]
	if numbers[i] > mostRolls:
		mostRolls = numbers[i]
		most = i
	i += 1

print(f"And the total adds up to {total}! The number that was 'rolled' most was {numNames[most]} with {numbers[most]} rolls!")



    How long would it take to make a coin land on heads 10 times in a row?

    Let’s say 1 is heads, and 2 is tails. And let’s say that one toss takes 7 seconds.

    This program uses the secsToDHM function.

    heads = 0; tosses = 0
while(heads < 10):
	toss = Random.randint(1,2)

	if toss == 1:
		heads += 1
	else:
		heads = 0

	tosses += 1


print(f"It took {tosses} tosses ({secsToDHM(7 * tosses)})")


# How many spins does it take on a roulette wheel to hit zero X times in a row?
# We'll go with 30 seconds per spin for this one
spins = 0; green = 0
while(green < 4):
	spins += 1
	spin = Random.randint(1,37) # 37 is green

	if spin == 37: green += 1
	else: green = 0

print(f"It took {spins} spins to hit green 4 times in a row ({secsToDHM(30 * spins)})")

  • “Prettify” seconds

    secsToDHM (seconds)

    This “prettifies” seconds by returning a string of the amount of hours and minutes the given seconds convert to. Days are also included, if hours are 24 or over. Example of a returned string:
    “3 days, 8 hours, 23 minutes”

    def secsToDHM(seconds: int) -> str:
	minutes = round(seconds / 60)
	hours = round(minutes / 60)
	remM = minutes % 60
	days = 0

	if hours >= 24:
		days = round(hours / 24)
		remH = hours % 24

	if (days > 0):
		return f"{days} days, {remH} hours, {remM} minutes"

	return f"{hours} hours, {remM} minutes"

  • Python (3)

    This is where I will document my progress in learning Python.

    One key aspect when first starting with Python is that it differs from other languages in that commands are not necessarily ending with a semicolon, and blocks are not defined by { and }. Instead, commands end where the line ends, and blocks are defined by indetation (a tab, or spaces). Example:

    1) print("Hello world!")
    2) print("Hello!"); print("Hello, world I mean!)

    The first example above is all you need for the program to work. No semicolon is needed.
    The second one, there are two commands on a single line, so a semicolon is needed to separate them.

    Intendation

    Intendantion is needed to form a new block. In C and many other languages, it is usually done like this:

    if (x > y)
    {
    print("Yes, x is indeed larger than y");
    }

    While in Python, the same would be achieved like this:

    if x > y:
    print(“Yes, x is indeed larger than y”)
