python中比较两个列表的实例方法

cmp(list1, list2)

#!/usr/bin/python

list1, list2 = [123, 'xyz'], [456, 'abc']

print cmp(list1, list2);

print cmp(list2, list1);

list3 = list2 + [786];

print cmp(list2, list3)

print((a>b)-(a<b))　＃０，表示俩ｌｉｓｔ相等

import operator

 

a=[1, 2, 3, 4, 5 ]

b=[1, 2, 3, 4, 5,6 ]

c=[1, 2, 3, 4, 5 ]

print(operator.lt(a,b)) #=> True ,小于<

print(operator.gt(a,b)) #=> False ,大于>

print(operator.eq(a,c)) #=> True ,等于==

print(operator.ne(b,a)) #=> True ,不等于!=

print(operator.le(a,b)) #=> True ,小于等于<=

print(operator.ge(b,a)) #=> True ,大于等于>=

a=[]
b=[]
while(len(a)!=4):
  x=randint(0,9)
  if x not in a:
    a.append(x)
    
while(len(b)!=4):
  x=randint(0,9)
  if x not in b:
    b.append(x)
    
print(a)
print(b)
print()
k1=k2=0
for i in range(4):
  if a[i]==b[i]:
    k1+=1
  if b[i] in a and b[i]!=a[i]:
    k2+=1
    
print('k1=',k1)
print('k2=',k2)
