I am learning python. I wanted to test my ability by making a program to
keep track of the flip of a coin to find how many consecutive times it came
up heads and tails.
Just want some criticism on what I have done.
import random
Hn = {}
Tn = {}
for i in range (0,31):
vars()["Hn"+str(i)] = 0
for i in range (0,31):
vars()["Tn"+str(i)] = 0
total_Heads = 0
total_tails= 0
tails_number = 0
Heads_number = 0
tries = 0
while tries < 10000:
tries += 1
coin = random.randint(1, 2) # Flip coin
if coin == 1:
Heads_number += 1 # Incroment Heads count
total_Heads += 1
if tails_number > 0 :
vars()["Tn"+ str(tails_number)] += 1 # Incroment tails
consecutive count
tails_number = 0
if coin == 2:
tails_number += 1 # Incroment Talies count
total_tails += 1
if Heads_number > 0:
vars()["Hn"+ str(Heads_number)] += 1 # Incroment Heads
consecutive count
Heads_number = 0
print (tries)
print (total_tails, total_Heads)
for i in range (30):
print ('%-15s %-15s' %(("Tn"+str(i)+"
"+str(eval("Tn"+str(i)))),("Hn"+str(i)+" "+str(eval("Hn"+str(i))))))
print out
