Suppose that we have a conditional statement:
In Python, we can write it in three ways:
f = lambda x: x > 2 and (x + 1) or 0or
f = lambda x: 0 if x <= 2 else (x + 1)or
f = lambda x: [x + 1, 0][x <= 2]However, if the number of conditions if more than 2, it is best to use the first method.
For example, consider this conditional statement:
Here is the Python code:
f = lambda x: (x >= 5 and x+1) or \
( (x < 5 and x > 2) and 3 ) or 0We read it as:
if x >= 5, f(x) = x + 1
else, if 2 < x < 5, f(x) = 3
else, f(x) = 0
