[Tutor] I flip a coin 1 million times what is the consecutive times it will come up head and come up tails

[shaeffer at q.com]

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
