Sending an Email when temperature Crosses Threshold

Error in code for the project “sending an Email when temperature crosses threshold.” error showing like
this : IndentationError: unindent does not match any outer indentation level

I think you are using python out there and python unlike many other programming languages uses indentation rather than curly braces to determine scope of a given variable or function or the conditionals, so make sure you have set the indentation properly.
Indentation means the alignment, look up for this documentation for more info:

Make sure you have properly used indentation in your code for the scope of a function

The solution you have given is worked.Thank you very much

Thanks for the help.
