l = list(map(lambda x: x+n, l)) what does this do
Question:
l = [1,2,3,4,5,6,7,8]
print("list : ", l)
n = int(input('N: '))
l = list(map(lambda x: x+n, l))
print("new list : ", l)
l = list(map(lambda x: x+n, l)) how does this code works?
Answers:
lambda use to create function (like def, but it’s inline)
lambda x: x+n mean you insert x as parameter and it will return x+n
For example
f1 = lambda x: x+5
print(f1(10))
result is 15

map use to apply function to every element in that list or list like such as tuple, array
see more here link
so in your case, if you input n=1, result is l=[2,3,4,5,6,7,8,9]
This code add n to each element of the list. Read more about map and lambda function on https://docs.python.org/3/library/functions.html#map and https://python-reference.readthedocs.io/en/latest/docs/operators/lambda.html
