Comparisons in depth

Chain comparisons, compare text reliably, check for None with is, and compare floating-point numbers safely.

You will be able to

• Write range conditions as chained comparisons such as 18 <= temp <= 24
• Compare strings without being caught out by letter case or stray spaces
• Explain the difference between == and is, and use is only for None
• Compare floating-point results with a tolerance instead of ==
