Probability

Question

Hi!
so iv got a little probability expirement and iv got a error in this code:

import random
for i in range(20):
ran = random.randint(1,6)
ran1 = random.randint(1,6)
print(ran + ran1)

import re
pattern = 7
print(len(re.findall(pattern,i)))

----------------------------------------
in the code i want to print the number of times the number 7 apears in the random numbers range but it do not work...

PLEAS HELP ME!

Answer 1

My advice would to append the sum (ran + ran1) to a list (call it my_list for example) and then do my_list.count(7) at the end.

import random
my_list = []

for i in range(20):
ran = random.randint(1,6)
ran1 = random.randint(1,6)
my_list.append(ran + ran1)

print(my_list.count(7))

Answer 2

The problem there is that, with each iteration, you are creating a new empty list called 'test'. What you want is a list to be created before the for loop.

Answer 3

Do you mean like this?:

import random
for i in range(100):
ran = random.randint(1,6)
ran1 = random.randint(1,6)
test = []
test.append(ran + ran1)
result = test.count(7)
print(result)
