Please help!

Problem 1 Write a function first_n that accepts a list 1 and an int n and returns a list containing the first n items of 1. Your code should work for any value of n > 0. In the event that n is greater than the length of 1 , the entire list I should be returned. When n is 0, the empty list [] would be returned. In [ ]: # write your function in this cell In [ ]: # test your function in this cell, adding any additional cells you require Problem 2 Write a function list_average that takes a list 1 as its argument and returns the average of the values in l. In [ ]: # write your function in this cell In [ ]: # test your function in this cell, adding any additional cells you require Problem 3 Write a function list_variance that takes a list 1 as its argument and returns the variance of the values in l. In [ ]: # write your function in this cell In [ ]: # test your function in this cell, adding any additional cells you require Problem 4 Write a function vector_magnitude that takes a list v as its argument and returns the the magnitude of v. In [ ]: # write your function in this cell In [ ]: # test your function in this cell, adding any additional cells you require Problem 5 Write a function dot_product that takes two lists v1 and v2 and returns their scalar product. It's ok to assume that v1 and v2 will be of equal length, although in production code we would check that that necessary condition is satisfied. In [ ]: # write your function in this cell In [ ]: # test your function in this cell, adding any additional cells you require
