Heads or Tails

headtails.py

import numpy as np
np.random.seed(123)
outcomes = []
for x in range(10) :
    coin = np.random.randint(0, 2)
    if coin == 0 :
        outcomes.append("heads")
    else :
        outcomes.append("tails")

print(outcomes)

['heads', 'tails', 'heads', 'heads', 'heads', 
 'heads', 'heads', 'tails', 'tails', 'heads']

Heads or Tails: Random Walk

headtailsrw.py

import numpy as np
np.random.seed(123)

tails = [0]

for x in range(10) :
    coin = np.random.randint(0, 2)
    tails.append(tails[x] + coin)

print(tails)

[0, 0, 1, 1, 1, 1, 1, 1, 2, 3, 3]
Intermediate Python

Step to Walk

outcomes

['heads', 'tails', 'heads', 'heads', 'heads', 
 'heads', 'heads', 'tails', 'tails', 'heads']

tails

[0, 0, 1, 1, 1, 1, 1, 1, 2, 3, 3]
