## 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

Python: Get the Key Whose Value Is Maximal in a Dictionary

```>>> model_scores = {'model_a': 100, 'model_z': 198, 'model_t': 150}
>>> # workaround
>>> keys, values = list(model_scores.keys()), list(model_scores.values())
>>> keys[values.index(max(values))]
'model_z'
>>> # one-line
>>> max(model_scores, key=model_scores.get)
'model_z'
```
