Python-cmp()方法
的cmp()是，其比较两个整数Python标准库的一部分。如果第一个整数小于第二个，则比较结果为-1，如果第一个整数大于第二个，则比较结果为1。如果两者相等，则结果cmp()为零。
下面的示例说明了显示cmp()方法使用情况的不同场景。
示例
def cmp(x, y):
return (x > y) - (x < y)
#x>y
x = 5
y = 3
print("The cmp value for x>y is : ",cmp(x, y),"\n")
#x<y
x = 7
y = 9
print("The cmp value for x<y is : ",cmp(x, y),"\n")
#x=y
x = 13
y = 13
print("The cmp value for x=y is : ",cmp(x, y))
#odd and even
k = 16
if cmp(0, k % 2):
print("\n","The given number",k,"is odd number ")
else:
print("\n","The given number",k,"is even number")
k= 31
if cmp(0, k % 2):
print("\n","The given number",k,"is odd number")
else:
print("\n","The given number",k,"is even number")输出结果
运行上面的代码给我们以下结果-
The cmp value for x>y is : 1 The cmp value for x<y is : -1 The cmp value for x=y is : 0 The given number 16 is even number The given number 31 is odd number
