serial-core

The serial-python Python library provides extensible tools for reading and writing record-oriented data in various formats. The core library provided here is contained in the serial.core package. Library extensions will be contained in their own packages under the serial namespace.

Features

• Read/write delimited and fixed-width data
• Named, typed, and formatted data fields
• Filtering
• Aggregation
• Sorting

Basic Example

""" Read a comma-delimited file.

"""
from serial.core import DelimitedReader
from serial.core import IntField
from serial.core import StringField

def name_filter(record):
    """ Convert name to upper case. """
    record["name"] = record["name"].upper()
    return record

fields = (
    StringField("name", 0),
    IntField("age", 1)
)
with DelimitedReader.open("ages.csv", fields, ",") as reader:
    reader.filter(name_filter)
    for record in reader:
        print("{name} is {age} years old".format(**record))
