# integers following Normal distribution

Hello,

how can I produce positive integers, say in (1,n), which follow the normal distribution with parameters (m,sigma).

Thanks.

I think it is pretty self explanatory:

```
# Sample size (not counting negatives!)
sample_size = 10000
# Parameters of the distribution
mean = 10
sigma = 10
dist = RealDistribution('gaussian', sigma)
# Getting the elements (notice the 'mean' in 'event'!)
sample = []
while len(sample) < sample_size :
event = round(mean + dist.get_random_element())
if event >= 0 :
sample.append(event)
# Getting the frequencies and plotting
sample_range = range(min(sample),1+max(sample))
frequencies = [sample.count(i) for i in sample_range]
list_plot(zip(sample_range,frequencies),gridlines=[[mean,mean-sigma,mean+sigma],[]])
```
