### Create and Populate Bloom Filter

Source: https://pybloomfiltermmap3.rtfd.io

Demonstrates creating a Bloom filter with a specified capacity and error rate, and populating it with words from a dictionary file. Ensure the dictionary file path is correct.

```python
from pybloomfilter import BloomFilter

bf = BloomFilter(10000000, 0.01, 'filter.bloom')
with open("/usr/share/dict/words") as f:
    for word in f:
        bf.add(word.rstrip())

print 'apple' in bf

```

### Copy and Update Bloom Filter Template

Source: https://pybloomfiltermmap3.rtfd.io

Shows how to create a new Bloom filter based on the template of an existing one and update it with a new set of elements. The resulting filter can be serialized to a base64 string.

```python
fruitbf = bf.copy_template("fruit.bloom")
fruitbf.update(("apple", "banana", "orange", "pear"))

print(fruitbf.to_base64())

```
