Extracting array data with Python directly from .fit file

Hi everyone! I'm new here and I'm trying to simply read son data like power or cadence and put it in a chart, it's just for fun and creating chart with matplotlib and Python. I already read the Profile.xls file and just can´t figure out how to extract data. I found nothing in internet and just want a code example how to do that. Im stuck in the basic example with Profile[][] . Thanks in advance if somebody can help with it.

Take a look at the FIT Python SDK. The data that you are looking for will be in the Record messages. If you inspect the dictionary returned by the decoder's read method, you will see them. Profile.xls is a good reference for the fields that you can expect in the Record messages, if the data is present in the file.

The example code that accompanies the Decoding FIT Activity Files recipe is in C#, but the information on what data to expect in the file still applies. The Python SDK implements the generic messages handlers for you. Look for the Session, Lap, Record, etc messages in the dictionary that the read method returns.
