Python has a type of variable called bool. It has two possible values: True and False.
In [1]:
x = Trueprint(x)
print(type(x))
True
<class 'bool'>
Rather than putting True or False directly in our code, we usually get boolean values from boolean operators. These are operators that answer yes/no questions. We'll go through some of these operators below
| Operation | Description | Operation | Description | |
|---|---|---|---|---|
a == b |
a equal to b |
a != b |
a not equal to b |
|
a < b |
a less than b |
a > b |
a greater than b |
|
a <= b |
a less than or equal to b |
a >= b |
a greater than or equal to b |

def can_run_for_president(age):
*"""Can someone of the given age run for president in the US?"""# The US Constitution says you must be at least 35 years old*return age >= 35
print("Can a 19-year-old run for president?", can_run_for_president(19))
print("Can a 45-year-old run for president?", can_run_for_president(45))
Can a 19-year-old run for president? False
Can a 45-year-old run for president? True
Comparisons frequently work like you'd hope.
