python-tcxparser

python-tcxparser is a minimal parser for Garmin's TCX file format. It is not in any way exhaustive.

Data extracted:

• latitude & longitude of start point of workout
• type of workout (running, walking, etc)
• time of completion of workout (in ISO UTC)
• distance of workout (in meters)
• duration of workout (in seconds)
• calories burned during workout (as estimated by device)
• average, max and min heart rate during workout
• average pace during workout
• average altitude during workout
• ascent and descent of workout
• max and min altitude
• time stamp of each data point (in ISO UTC)
• average and max cadence (cycling activities)
• percentage and time spent in heart rate zone
• average and max power
• total steps (also strokes)

Installation

Install it from PyPI:

pip install python-tcxparser

Usage

Basic usage example:

>>> import tcxparser
>>> tcx = tcxparser.TCXParser('/home/vinod/Downloads/20121226-212953.tcx')
>>> # Duration of workout in seconds
... tcx.duration
1992.78
>>> # latitude/longitude at start of workout
... tcx.latitude
35.951880198
>>> tcx.longitude
-79.0931872185
>>> tcx.activity_type
'running'
>>> # ISO UTC timestamp when workout completed
... tcx.completed_at
'2012-12-26T22:03:05Z'
>>> # distance of workout in meters
... tcx.distance
4686.31103516
>>> tcx.distance_units
'meters'
>>> # calories burned (as reported by device)
... tcx.calories
379
>>> # percentage of workout spent in each user-defined heart rate zone
... tcx.hr_percent_in_zones({"Z0": (0, 99), "Z1": (100, 129), "Z2": (130, 200)})
{"Z0": 14, "Z1": 36, "Z2": 50}

Maintainer Information

We use Github Actions to lint (using pre-commit, black, isort, and flake8), test (using tox and tox-gh-actions), and calculate coverage (using coverage).

We have a local script to do these actions locally, named maintain.sh:

$ ./maintain.sh

A Github Action workflow also builds and pushes a new package to PyPI whenever a new Release is created in Github. This uses a project-specific PyPI token, as described in the PyPI documentation here. That token has been saved in the PYPI_PASSWORD settings for this repo, but has not been saved anywhere else so if it is needed for any reason, the current one should be deleted and a new one generated.

As always, be sure to bump the version in setup.py before creating a Release, so that the proper version gets pushed to PyPI.
