Compare & Bool.

Fourth class. A comparison asks a question and Python answers with a bool: True or False.

The <, <=, >, and >= operators compare order. == checks whether two values are equal, while != checks whether they differ. Do not confuse == with =: one equals sign assigns a value; two compare.

You can store the result:

temperature = 21
warm = temperature >= 20
print(warm)

warm is a bool whose value is True. The same pattern can mark whether a score passes a threshold, stock is exhausted, or BMI is below a boundary.

This lesson only creates and prints boolean results. In the next lesson, if will use such results to choose different paths.

Common mistakes: using = instead of == for equality, or writing the string "True" instead of the boolean True.
