In python3, simply do this:
from functools import reduce
then you can use reduce as explained in the video.

in your first step of explanation you said x is give 1 and y is given 1 here i'm confused just want to know where is given y=1. I think you're wrong here….it must be x=1 and y=2 in your first step.

In newer version of python….u gotta import it from functools

can i use list comprehension to replace lambda reduce function? some say yes, some say no. please use this as the example, i really appreciate if someone can help me with this. Here is how i got the result by using lambda.
from functools import reduce
n = [23, 45, 68, 23, 45, 35]
result = (reduce(lambda x, y: x * y, n))
print(result)
the result is 2549515500.

how about list comprehension?

In the first step, first two elements of sequence are picked and the result is obtained.
1 2 =2
3 2 =6
4 6 =24
5 24 =120

Thank u👍👍
