(Please answer all questions below in 25 minutes ) Q1:Fibonacci sequence can be expressed as: 1, 1, 2, 3, 5, 8, 13, 21, 35…Write a function of fib(n) and return the nth number in the fibonacci number (n starts from 0). ( hints: using recursive function )
Q2: a = [1, 2, 3, 4], b= [11,22,33,44] using map function to get list the c = [12, 24, 36,48], where 12 = 1+11, 24 = 22+2, 26 =33+3, 48= 44+4. (hints: map and lambda function)
Q3: There are two lists below: names = ['Jack', 'Tom', 'Peter', 'David'], scores = [89, 78, 92, 86] The items in list names and list scores are responding to each other.Writing a dictionary with list names as the keys, and list scores as the values. (hints: there are many methods in creating a dictionary, could use for or zip function here)
Q4: There are two lists: a = [1,2,3,4], and b = [11,12,13,14]. Do some operations thus making a = [1,2,3], b =[11,4,12,13,14] (hints: basic list operations)
Q5: Assuming there is a goal(a, b) function which returns a list [a, b, a+b]. Please try to insert the goal(a, b) function into the class Object below, thus that the self.items be the return value of the original goals functions. (hints: methods in defining a class)
