1)Given two lists L1 and L2, create a new list L3 consisting of the first element of L1 and the last element of L2. For example, if L1=[1,2,3] and L2=["a","b","c"], L3 should be [1,"c"]

2)given a string s, create a new string odd_letters that contains only the odd letters of s (two ways to solve this problem are to use slicing, or a while or for loop), i.e. starting at the first letter or the zeroth index: if s="banana", odd_letters should be "bnn"

3)Given a list of numeric variables L, assign a variable all_big that is True if all of the elements of L are >1000, False otherwise

in python!!

1)Given two lists L1 and L2, create a new list L3 consisting of the first element of L1 and the last element of L2. For example, if L1=[1,2,3] and L2=["a","b","c"], L3 should be [1,"c"]
L3 = [L1[0], L2[-1]]

2)given a string s, create a new string odd_letters that contains only the odd letters of s (two ways to solve this problem are to use slicing, or a while or for loop), i.e. starting at the first letter or the zeroth index: if s="banana", odd_letters should be "bnn"
odd_letters = ""
for i in range(0,len(s),2):
    odd_letters += s[i]

3)Given a list of numeric variables L, assign a variable all_big that is True if all of the elements of L are >1000, False otherwise
all_big = True
for x in L:
    if(x <= 1000):
        all_big = False
        break

    Python help: Given the lists, lst1 and lst2, create a new sorted list consisting of all the elements of lst1 that also appears in lst2. For example, if lst1 is [4, 3, 2, 6, 2] and lst2 is [1, 2, 4], then the new list would be [2, 2, 4]. Note that duplicate elements in lst1 that appear in lst2 are also duplicated in the new list. Associate the new list with the variable new_list, and don't forget to sort...
