def get_file_hash(path, algorithm='md5'):
"""Get hash from a given file and hashing algorithm.
Args:
path: str.
Full path to a file.
algorithm: str, optional.
Name of hashing algorithm. See `hashlib.algorithms_available`
for list of available hashing algorithms in python.
Returns:
str. File hash computed from the file using the specified algorithm.
#### Examples
```python
get_file_hash('train.gz')
## '5503d900f6902c61682e6b6f408202cb'
""" hash_alg = hashlib.new(algorithm) with open(path, 'rb') as f: read_size = 1024 1024 4 data = f.read(read_size) while data: hash_alg.update(data) data = f.read(read_size) return hash_alg.hexdigest() ```
