xphyle 2.2.0

Utilities for working with files.

Latest Version: 3.1.6

xphyle: extraordinarily simple file handling

xphyle is a small python (3.3+) library that makes it easy to open compressed files. Most importantly, xphyle will use the appropriate program (e.g. ‘gzip’) to compress/uncompress a file if it is available on your system; this is almost always faster than using the corresponding python library. xphyle also provides methods that simplify common file I/O operations.


pip install xphyle

If you are using python 3.3 or 3.4, this will install one dependency: backports.typing.

Example usages:

from xphyle import *
from xphyle.paths import STDIN, STDOUT

# Open a compressed file...
myfile = xopen('infile.gz')

# ...or a compressed stream
# e.g. gzip -c afile | python
stdin = xopen(STDIN)

# Easily write to the stdin of a subprocess
with open_('|cat', 'wt') as process:

# We have to tell xopen what kind of compression
# to use when writing to stdout
stdout = xopen(STDOUT, compression='gz')

# Print all lines in a compressed file...
with open_('infile.gz') as myfile:
    for line in myfile:

# ... or a compressed URL
with open_('') as myfile:
    for line in myfile:

# Transparently handle paths and file objects
def dostuff(path_or_file):
    with open_(path_or_file) as myfile:
        for line in myfile:

# Read all lines in a compressed file into a list
from xphyle.utils import read_lines
lines = list(read_lines('infile.gz'))

# Sum the rows in a compressed file where each line is an integer value
total = sum(read_lines('infile.gz', convert=int))

See the Documentation for full usage information.


Future releases are mapped out using GitHub Projects.


We welcome any contributions via pull requests. Style-wise, we try to adhere to the Google python style guidelines. We use Google-style docstrings, which are formatted by the Napoleon Sphinx Plugin. We run pylint as part of each build and strive to maintain a 10/10 score. However, we disable some pylint checks:

  • Function annotations: pylint does not properly handle whitespace around function annotations (
  • White space on empty lines: we use white space as a visual guide to the structure of the code. Each blank line should have whitespace matching the indent level of the next non-blank line.
  • Checks that are arbitrary/overly restrictive (e.g. ‘too-many-xxx’; see .pylintrc for full list)
