Note 04: Branching¶

Branching lets a program choose between actions.

temperature = float(input("Temperature: "))

if temperature < 32:
    print("Freezing")
elif temperature < 60:
    print("Cool")
else:
    print("Mild or warm")

Comparisons¶

Use comparison operators such as ==, !=, <, <=, >, and >=.

Logical operators combine conditions:

and
or
not

Check the Boundaries¶

When a program splits values into ranges, test values at the edges of those ranges. Boundary mistakes are common and worth catching early.
