Syntax error when passing indicators which start with numbers to IndicatorFactory

[NowBothWhiteAndRed]

Hi,

Just noticing the following:

vbt.IndicatorFactory(output_names=['real'], input_names=['1d_max']).from_apply_func(lambda ts: ts).run(new_indicator)

produces: {SyntaxError}invalid syntax (factory.py, line 2)

but:

vbt.IndicatorFactory(output_names=['real'], input_names=['a_1d_max']).from_apply_func(lambda ts: ts).run(new_indicator)

works fine

Not sure if it's an issue or not but seems odd enough to note.

That’s expected because it generates object properties from your input and output names, and properties as any other variables in Python cannot start with a number.

Got it, thanks
