Python operator.ne()用法及代码示例


operator.ne() 函数

operator.ne()函数是一个库函数operator模块,用于对两个值执行“不等于操作”并返回True如果第一个值不等于第二个值,False,否则。

模块:

    import operator

用法:

    operator.ne(x,y)

参数:

  • x,y– 要比较的值。

返回值:

这个方法的返回类型是bool,它返回True如果x不等于yFalse,否则。

范例1:

# Python operator.ne() Function Example

import operator

# integers
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()

# strings
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()

# printing the return type of the function
print("type((operator.ne(x,y)):", type(operator.ne(x,y)))

输出:

x:10 , y:20
operator.ne(x,y): True
operator.ne(y,x): True
operator.ne(x,x): False
operator.ne(y,y): False

x:Apple , y:Banana
operator.ne(x,y): True
operator.ne(y,x): True
operator.ne(x,x): False
operator.ne(y,y): False

type((operator.ne(x,y)): <class 'bool'>

范例2:

# Python operator.ne() 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.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
