Answer 1

Task 1

# a list with 5 elements and 3 data types: String, Int, Float
aList = ["Chegg", 100, 12.34, "India", 90]

# indices start from 0. So, the indices of above list are 0, 1, 2, 3 and 4

# second element has index 1
print("Second element:", aList[1])

# last element has index 4
print("Last element:", aList[4])

# negative index is to get the items from last and they start from -1

# last but one can be accessed using index -2
print("Negative index (fourth element):", aList[-2])

# last but one item using positive index
print("Positive index (fourth element):", aList[3])

# len is a method that gives the length of the list
print("Lengt:", len(aList))

# One question at a time please -- Policy of Chegg.
