1.布尔类型
Python有一种称为bool的变量类型。它有两个可能的值：True和False。
In [1]:
x = True
print(x)
print(type(x))
True
<class 'bool'>
除了直接在代码中使用True或False之外，我们通常通过布尔运算符获取布尔值。这些运算符用于回答是/否问题。让我们来看一些这些运算符。
1.1比较运算
| 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 |

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?
