Truthy and falsy values

Use any value as a condition, know which values count as false, and decide when an explicit comparison is safer.

You will be able to

• List the common falsy values: False, 0, 0.0, an empty string and None
• Use a string or number directly as a condition, as in if name:
• Explain why if value: treats a real 0 as missing
• Choose between a truthiness check and an explicit comparison
