Python Math: Casino simulation
Python Math: Exercise-70 with Solution
Write a Python program for casino simulation.
Sample Solution:-
Python Code:
#https://gist.github.com/ivanGzz/243a453ba6499a49027c19cac60471f6
import random
import math
limit = 1000
acc = 0
results = []
exp = 1000
for i in range(exp):
color = 0
amount = 10000
max_amount = amount
bid = 1
count = 0
while count < limit and amount > 0 :
amount = amount - bid
next = random.randint(0, 1)
if next == color :
amount = amount + bid + bid
bid = 1
# color = 1 if color == 0 else 0
if amount > max_amount:
max_amount = amount
else :
bid = bid + bid
count = count + 1
acc = acc + max_amount
results.append(max_amount)
print("Exp {}".format(i))
avg = acc / exp
acc = 0
for i in range(len(results)):
acc = acc + math.pow(results[i] - avg, 2)
std = math.sqrt(acc / exp)
print("Average max amount earned {} with standard deviation {}".format(avg, std))
Sample Output:
Exp 0 Exp 1 Exp 2 Exp 3 Exp 4 Exp 5 ---- Exp 998 Exp 999 Average max amount earned 10489.705 with standard deviation 56.22367806360589

Python: Tips of the Day
Find current directory and file's directory:
To get the full path to the directory a Python file is contained in, write this in that file:
import os dir_path = os.path.dirname(os.path.realpath(__file__))
(Note that the incantation above won't work if you've already used os.chdir() to change your current working directory, since the value of the __file__ constant is relative to the current working directory and is not changed by an os.chdir() call.)
To get the current working directory use
import os cwd = os.getcwd()
Documentation references for the modules, constants and functions used above:
- The os and os.path modules.
- The __file__ constant
- os.path.realpath(path) (returns "the canonical path of the specified filename, eliminating any symbolic links encountered in the path")
- os.path.dirname(path) (returns "the directory name of pathname path")
- os.getcwd() (returns "a string representing the current working directory")
- os.chdir(path) ("change the current working directory to path")
