python中逻辑运算符
Logical Operators:
逻辑运算符：
There are basically three types of logical operators as below:
基本上有以下三种类型的逻辑运算符：
- And
和
- Or
要么
- Not
不
There above operators semantics or meaning is the same as their meaning in English. To demonstrate we can take one simple example like a number can be greater then 2 and less then 5, so if we consider this example then we know that there could be only two possible numbers comes in between i.e. 3 and 4. So now let us run this example and verify the results by passing different numbers.
上面的运算符的语义或含义与英语中的含义相同。 为了说明这一点，我们可以举一个简单的例子，例如一个数字可以大于2，然后小于5，因此，如果考虑此示例，我们知道在3和4之间可能只有两个可能的数字。所以现在让我们运行此示例，并通过传递不同的数字来验证结果。
my_input = raw_input("Input any number less than 10 >>>")
print("Number entered was ") + my_input
my_input = int(my_input)
if (my_input > 2 and my_input < 5):
result = True
else:
result = False
print result
We have entered say 3 then the output of the above code will print as “True” because the condition satisfies that the passed number is greater than 2 and less than 3. The above code is a simple example of how to use “AND” logical operators in Python.
我们输入了3，则上述代码的输出将打印为“ True”，因为条件满足传递的数字大于2且小于3。以上代码是如何使用“ AND”逻辑的简单示例Python中的运算符。
Input any number less than 10 >>> 3
Number entered was 3 True
Now let us take similar example passing the same number as 3 but using “OR” condition stating can be less then 2 or less then 5 if any one of the condition matches then the result should be true.
现在让我们以类似的示例为例，该示例传递与3相同的数字，但是如果条件中的任何一个匹配，则使用“ OR”条件说明可以小于2或小于5，然后结果应该为true。
my_input = raw_input("Input any number less than 10 >>>")
print("Number entered was ") + my_input
my_input = int(my_input)
if (my_input < 2 or my_input < 5):
result = True
else:
result = False
print result
Below is the result when we passed “3” using OR logical operator to the conditions.
下面是当我们使用OR逻辑运算符将“ 3”传递给条件时的结果。
Input any number less than 10 >>> 3
Number entered was 3
True
And below if the False output as 6 does not fall under any criteria.
并且在以下条件下，如果False输出为6，则不属于任何条件。
Input any number less than 10 >>> 6
Number entered was 6
False
Now let us take an example on how to use “Not” logical operators. Say we have a result from some output and now our variable contains the value as 4 and let’s call the variable name as “abc”.
现在让我们举一个关于如何使用“非”逻辑运算符的例子。 假设我们从某个输出中得到了一个结果，现在我们的变量包含的值为4，我们将变量名称称为“ abc”。
Below is my condition to validate if the value from “abc” is present in the list?
以下是我要验证列表中是否存在“ abc”值的条件？
abc = 4
if abc not in [3,7,5] :
print("condition met")
else:
print("condition not met")
Result as below.
结果如下。
condition met
Now we know how to use logical operators in Python programming. This is a basic explanation on how to use Logical Operators in Python programming language.
现在我们知道了如何在Python编程中使用逻辑运算符。 这是有关如何在Python编程语言中使用逻辑运算符的基本说明。
