How do I log text and a variable in the same line in Python?

Question

I am relativly new to coding with Python.

I recently set up a gps logging device with a raspberry pi and I want to make my log file look cleaner.

My current code for logging is:

logging.info('Altitude:')
logging.info(gpsd.fix.altitude)

It logs:

INFO:root:Altitude:
INFO:root:80

What I want to see in the log is:

Altitude: 80

I tried to do this with my limited knowledge with python, but it only resulted in failure.

Thanks! Also, any other tips for cleaning up the log file?

Answer 1

In Python >=3.6 you can do this :

logging.info(f"Altitude: {gpsd.fix.altitude}")

By adding the "f" at the beginning of the string the value between brackets will be interpreted as a variable and will be replaced by its value.
