Show content of an AVRO file with Python

This note describes how we can show the content of an AVRO file with Python.
We use python3 as tool here. We use this from an Anaconda framework. I checked whether this installation already contained an AVRO package, but this wasn’t the case. Therefore, AVRO was downloaded (as avro-python3-1.8.2.tar.gz) and next command was issued: C:\ProgramData\Anaconda3\python.exe -m pip install C:\ProgramData\Anaconda3\avro-python3-1.8.2.tar.gz. The screen then looked like:
.
Once, AVRO was installed, an AVRO file can be created with:

import avro.schema
from avro.datafile import DataFileWriter
from avro.io import DatumWriter

schema = avro.schema.Parse(open('file.avsc', "r").read())

writer = DataFileWriter(open("users.avro", "wb"), DatumWriter(), schema)
writer.append({"name": "Alyssa", "favorite_number": 256})
writer.append({"name": "Ben", "favorite_number": 7, "favorite_color": "red"})
writer.close()

Here use was made of a file that contained the schema:

{"namespace": "example.avro",
 "type": "record",
 "name": "User",
 "fields": [
     {"name": "name", "type": "string"},
     {"name": "favorite_number",  "type": ["int", "null"]},
     {"name": "favorite_color", "type": ["string", "null"]}
 ]
}

When a file was created, it can be read as:

from avro.datafile import DataFileReader
from avro.io import DatumReader

reader = DataFileReader(open("users.avro", "rb"), DatumReader())
for user in reader:
    print (user)
reader.close()

This latter programme is nice: another avro file can be read. I downloaded another avro file (called twitter.avro) and the corresponding outcome looked like:

runfile('C:/Users/tmaanen/.spyder-py3/avroTomLees.py', wdir='C:/Users/tmaanen/.spyder-py3')
{'username': 'miguno', 'tweet': 'Rock: Nerf paper, scissors is fine.', 'timestamp': 1366150681}
{'username': 'BlizzardCS', 'tweet': 'Works as intended.  Terran is IMBA.', 'timestamp': 1366154481}
