can someone provide an example of the chain function?

Answer 1

This is an example.

from itertools import accumulate, takewhile, chain

nums = list(accumulate(range(8)))

#declare and initialize second list
nums2 = list(accumulate(range(10)))

#print both lists
print(nums)
print(nums2)

#chain function inside a list function produce a longer list that contains both elements of nums and nums2 like a chain
print(list(chain (nums ,nums2)))

Answer 2

from itertools import chain
num1=[1,2,3]
num2=[2,5,7]
nums=list(chain(num1, num2))

print (nums)

Answer 3

nice😉
