Code: Select all

# Conversion ºC to ºF
celsiusVar = indigo.variables[123456789]
tempVar = celsiusVar.getValue(float) 
indigo.variable.updateValue(987654321,str(tempVar * 9/5 + 32))

To control the number of decimal places in your temperature conversion output, you can format the result using Python's string formatting capabilities. Here's how you can modify your code to achieve the desired number of decimal places:

Code: Select all

# Conversion ºC to ºF
celsiusVar = indigo.variables[123456789]
tempVar = celsiusVar.getValue(float)

# Format the temperature with different decimal places
temp_no_decimals = f"{tempVar * 9/5 + 32:.0f}"  # No decimal places
temp_one_decimal = f"{tempVar * 9/5 + 32:.1f}"  # One decimal place
temp_two_decimals = f"{tempVar * 9/5 + 32:.2f}"  # Two decimal places

# Update variables with formatted temperature values
indigo.variable.updateValue(987654321, temp_no_decimals)
indigo.variable.updateValue(987654322, temp_one_decimal)
indigo.variable.updateValue(987654323, temp_two_decimals)

In this code:
- `:.0f`, `:.1f`, and `:.2f` control the number of decimal places in the formatted string. The `f` indicates that the value should be formatted as a float.
- `temp_no_decimals`, `temp_one_decimal`, and `temp_two_decimals` store the formatted temperature values with different decimal places.
- `indigo.variable.updateValue()` is called for each formatted temperature value to update the respective variables in Indigo.

Regarding your question about `getValue(float, default=xx)`, if you're not sure whether the value returned by `getValue()` will always be a float and you want to provide a default value in case it's not, you can indeed use the `default` parameter. However, it's optional, and if you don't provide it, the default value will be `None`. So, it depends on whether you expect `getValue()` to return non-float values and how you want to handle those cases. If you're confident that it will always return a float, you can omit the `default` parameter.

I copied your question verbatim into my chatGPT and got the following reply.

ChatGPT really is helpful for Python novices, but you need to check the output and if it does give code that errors then just paste the Indigo log error lines and it will reformat.

Code: Select all

print(f'{x} mph. {"" if x < 100 else "Holy Crap!"}')

x = 99
>>>  99 mph.

x = 100
>>> 100 mph. Holy Crap!
