arr1=['One','Two','Five'],arr2=['Three','Four']
like itertools.combinations(arr1,2) gives us ('OneTwo','TwoFive','OneFive')
I was wondering is there any way applying this to two different arrays.?I mean for arr1 and arr2.
Output should be OneThree,OneFour,TwoThree,TwoFour,FiveThree,FiveFour
You are looking for .product():
From the doc, it does this:
product('ABCD', 'xy') --> Ax Ay Bx By Cx Cy Dx Dy
product(range(2), repeat=3) --> 000 001 010 011 100 101 110 111
Sample code:
>>> x = itertools.product(arr1, arr2)
>>> for i in x: print i
('One', 'Three')
('One', 'Four')
('Two', 'Three')
('Two', 'Four')
('Five', 'Three')
('Five', 'Four')
To combine them:
# This is the full code
import itertools
arr1 = ['One','Two','Five']
arr2 = ['Three','Four']
combined = ["".join(x) for x in itertools.product(arr1, arr2)]
If all you wanted is OneThree,OneFour,TwoThree,TwoFour,FiveThree,FiveFour then a double for loop will do the trick for you:
>>> for x in arr1:
for y in arr2:
print(x+y)
OneThree
OneFour
TwoThree
TwoFour
FiveThree
FiveFour
Or if you want the result in a list:
>>> [x+y for x in arr1 for y in arr2]
['OneThree', 'OneFour', 'TwoThree', 'TwoFour', 'FiveThree', 'FiveFour']
["".join(v) for v in itertools.product(arr1, arr2)]
#results in
['OneThree', 'OneFour', 'TwoThree', 'TwoFour', 'FiveThree', 'FiveFour']
