Python operator.ne()函数与示例
operator.ne()功能
operator.ne()函数是运算符模块的库函数，用于对两个值执行“不等于运算”，如果第一个值不等于第二个值，则返回True，否则返回False。
模块：
import operator
语法：
operator.ne(x,y)
Parameter(s)：
x，y–要比较的值。
返回值：
此方法的返回类型为bool，如果x不等于y，则返回True，否则返回False。
范例1：
# Python operator.ne() Function Example
import operator
#整数
x = 10
y = 20
print("x:",x, ", y:",y)
print("operator.ne(x,y): ", operator.ne(x,y))
print("operator.ne(y,x): ", operator.ne(y,x))
print("operator.ne(x,x): ", operator.ne(x,x))
print("operator.ne(y,y): ", operator.ne(y,y))print()#弦
x = "Apple"
y = "Banana"
print("x:",x, ", y:",y)
print("operator.ne(x,y): ", operator.ne(x,y))
print("operator.ne(y,x): ", operator.ne(y,x))
print("operator.ne(x,x): ", operator.ne(x,x))
print("operator.ne(y,y): ", operator.ne(y,y))print()#打印函数的返回类型
print("type((operator.ne(x,y)): ", type(operator.ne(x,y)))输出：
x: 10 , y: 20operator.ne(x,y): Trueoperator.ne(y,x): Trueoperator.ne(x,x): Falseoperator.ne(y,y): False x: Apple , y: Bananaoperator.ne(x,y): Trueoperator.ne(y,x): Trueoperator.ne(x,x): Falseoperator.ne(y,y): False type((operator.ne(x,y)): <class 'bool'>
范例2：
# Python operator.ne() Function Example
import operator
#输入两个数字
x = int(input("Enter first number : "))
y = int(input("Enter second number: "))
#打印值
print("x:",x, ", y:",y)
#比较
if operator.ne(x,y):
print(x, "is not equal to", y)
else:
print(x, "is equal to", y)输出：
RUN 1: Enter first number : 10 Enter second number: 20 x: 10 , y: 20 10 is not equal to 20 RUN 2: Enter first number : 10 Enter second number: 10 x: 10 , y: 10 10 is equal to 10
