I want to check whether the elements in two arrays are different using Python.
I don't want to use numpy and sticking with general Python.
Here is an example below:
arr1 = [1,2,3,4,5,6,7]
arr2 = [1,2,3,4,5,6,7,8,9,10]
I expect the output to be [8,9,10]
So far I've tried to carry out a for loop
for x in range(len(arr1)):
for y in range(len(arr2)):
if arr1[x] != arr2[y]:
print(arr2[y])
But, I receive this as output from print statement - 2345678910134567891012456789101235678910123467891012345789101234568910
With python one-liner:
res = [x for x in array2 if x not in array1]
print(res) # Output : [8, 9, 10]
Equivalent method for conventional iteration
lst = []
for x in array2:
if x not in array1:
lst.append(x)
print(lst) # Output : [8, 9, 10]
