How to compare two lists in python?
date = "Thu Sep 16 13:14:15 CDT 2010"
sdate = "Thu Sep 16 14:14:15 CDT 2010"
dateArr = [] dateArr = date.split()
sdateArr = [] sdateArr = sdate.split()
Now I want to compare these two lists. I guess split returns a list. We can do simple comparision in Java like dateArr[i] == sdateArr[i], but how can we do it in Python?
a = ['a1','b2','c3']
b = ['a1','b2','c3']
c = ['b2','a1','c3']
# if you care about order
a == b # True
a == c # False
# if you don't care about order AND duplicates
set(a) == set(b) # True
set(a) == set(c) # True
By casting a, b and c as a set, you remove duplicates and order doesn't count. Comparing sets is also much faster and more efficient than comparing lists.
for i in arr1:
if i in arr2:
return 1
return 0
arr1=[1,2,5]
arr2=[2,4,15]
q=checkarrayequalornot(arr1,arr2)
print(q)
>>0
