Python operator.le（）函数与示例

operator.le()函数 (operator.le() Function)

operator.le() function is a library function of operator module, it is used to perform "less than or equal to operation" on two values and returns True if the first value is less than or equal to the second value, False, otherwise.

operator.le()函数是运算符模块的库函数，用于对两个值执行“小于或等于运算” ，如果第一个值小于或等于第二个值False ，则返回True ，否则返回。

Module:

模块：

    import operator

Syntax:

句法：

    operator.le(x,y)

Parameter(s):

参数：

x,y – values to be compared.
x，y –要比较的值。

Return value:

返回值：

The return type of this method is bool, it returns True if x is less than or equal to y, False, otherwise.

此方法的返回类型为bool ，如果x小于或等于y ，则返回True ，否则返回False 。

Example 1:

范例1：

# Python operator.le() Function Example
import operator
# integers
x = 10
y = 20
print("x:",x, ", y:",y)
print("operator.le(x,y): ", operator.le(x,y))
print("operator.le(y,x): ", operator.le(y,x))
print("operator.le(x,x): ", operator.le(x,x))
print("operator.le(y,y): ", operator.le(y,y))
print()
# strings
x = "Apple"
y = "Banana"
print("x:",x, ", y:",y)
print("operator.le(x,y): ", operator.le(x,y))
print("operator.le(y,x): ", operator.le(y,x))
print("operator.le(x,x): ", operator.le(x,x))
print("operator.le(y,y): ", operator.le(y,y))
print()
# printing the return type of the function
print("type((operator.le(x,y)): ", type(operator.le(x,y)))

Output:

输出：

x: 10 , y: 20
operator.le(x,y):  True
operator.le(y,x):  False
operator.le(x,x):  True
operator.le(y,y):  True
x: Apple , y: Banana
operator.le(x,y):  True
operator.le(y,x):  False
operator.le(x,x):  True
operator.le(y,y):  True
type((operator.le(x,y)):  <class 'bool'>

Example 2:

范例2：

# Python operator.le() Function Example
import operator
# input two numbers
x = int(input("Enter first number : "))
y = int(input("Enter second number: "))
# printing the values
print("x:",x, ", y:",y)
# comparing
if operator.le(x,y):
print(x, "is less than or equal to", y)
else:
print(x, "is not less than or equal to", y)

Output:

输出：

RUN 1:
Enter first number : 10
Enter second number: 20
x: 10 , y: 20
10 is less than or equal to 20
RUN 2:
Enter first number : 20
Enter second number: 10
x: 20 , y: 10
20 is not less than or equal to 10
