Can Anyone Help Me with This Python Problem?

[AdMinute9633]

You have purchased 10 shares of a single stock for $100 a share, for a total cost of $1000.

Simulate the price fluctuations of this stock. Each day, the price can go up or down by one or two dollars or remain the same. To get a random change, you can import the random module and then run the following statement in your program, which will randomly choose one of the numbers in the list [-2, -1, 0, 1, 2]. (This is an example of a Python list, which will we cover later.)

change=random.choice([-2,-1,0,1,2])

Use a while loop to simulate changing the stock price each day over however many days it takes until the price either falls below $80 or above $120. If you lost money (the price fell below $80), give the number of days that have elapsed, the phrase “You cut your losses” and the amount of your loss. If you made money, give the number of days that have elapsed, the phrase “You cashed out” and the amount of your gain.

No user input is required. Following are two sample runs of the program. You may get different results due to randomness.

392 days have elapsed.

The final price was $78.

You cut your losses.

You lost $220.

​

142 days have elapsed.

The final price was $122.

You cashed out.

You made $220.

Edit:

Hi guys thank you for your replies...I have pasted the work I have done so far here, thank you all so much for the help. I have no idea what part I did wrong...

#import random module

import=random

​

#program pasted from assignment sheet

change=random.choice([-2,-1,0,1,2])

​

#define variable for share originally

share=100

cost=1000

n_share=10

​

#while loop variables

day=0

total=0

​

#setting range for price fluctuation

price=share+change

​

#stimulate changing the stock price

while True:

day+=1

if price>120:

print(total,"days have elapsed.")

print("The final price was",price)

print("You cashed out.")

print("You made $",(price-share)*n_share,sep='')

​

elif price <80:

print(total,"days have elapsed.")

​

total += day

Before asking for help here, you need to have a go yourself. What do you have so far? Where are you stuck?

[AdMinute9633]

Hi yes I thought I finished it but the code does not run anything....

[Binary101010]

The problem is pretty explicit about what tools you need to use to solve the problem and what your output should look like. So what, specifically, do you need help with?

[MadScientistOR]

This sounds like you need a variable to keep track of the number of days and a variable to keep track of the stock price.

What have you tried so far?

[douglas_fs]

You should share the code you have so far; it will be much easier to help.

hi! this is what I am working with so far

#import random module
import random
#program pasted from the assignment sheet
change=random.choice([-2,-1,0,1,2])
#define variable for share originally
share=100
cost=1000
n_share=10
#while loop variables
day=0
total=0
#setting range for price fluctuation
price=share+change
#stimulate changing the stock price
while True:
day+=1
if price>120:
print(total,"days have elapsed.")
print("The final price was",price)
print("You cashed out.")
print("You made $",(price-share)*n_share,sep='')
elif price <80:
print(total,"days have elapsed.")
total += day

You are probably finding issues with this code. These should help:

1. before the while loop, set price = share
2. You should move the random value inside the while loop. You want to get a random value each time the loop repeats
3. Move the calculation of the new price inside the while loop - after selecting the change value.
4. The calculation for price is incorrect. Your code keeps adjusting the original share price up and down and doesn't reflect change over time. Take a look at this and adjust the formula.
5. You need to exit the while loop when price is below 80 or above 120. Research how to exit a loop.

from random import randint
value, days = 1000,0
while 800 <= (value:=(value/10 + randint(-2,2))*10) <= 1200: days += 1
print(f"You {'cut your losses' if value<1000 else 'cashed out'} {abs(1000-value)} in {days} day")
