IndexError: tuple index out of range in python by using Raspberry pi

Question

Here is a code for calculating the radiation of the sun, but when I'm trying to run the code I get this error:

   Parsed config:  None
Traceback (most recent call last):
  File "/home/pi/SolarRadiationPlugin-master/run_plugin.py", line 13, in <module>
    print('Sunrise: {0}\r\nSunset: {1}'.format(solar_radiation.get_sunrise_sunset()))
IndexError: tuple index out of range

I'm not sure why this error is showing,

and here is the main code code :

Answer 1

solar_radiation.get_sunrise_sunset() returns a tuple of length 2. To use it with string formatting, you can unpack the tuple with *.

print('Sunrise: {0}\r\nSunset: {1}'.format(*solar_radiation.get_sunrise_sunset()))

In my opinion, you can improve readability by defining the values before the print.

sunrise, sunset = solar_radiation.get_sunrise_sunset()
print('Sunrise: {0}\r\nSunset: {1}'.format(sunrise, sunset))

or with f-strings

sunrise, sunset = solar_radiation.get_sunrise_sunset()
print(f'Sunrise: {sunrise}\r\nSunset: {sunset}'
