def count_types(lst: List[Any]) -> List[int]: """ Given a list <lst> of random types, return the number of occurrences of each type, in the form of a list, in the order that they were first seen.
For example, if the input ['str1', 1, 'str2'], the output would be [2, 1], as a string type appears first, and occurs twice in the list. An integer type appears next, and only occurs once in the list.
Another example could be [True, 'str1', 1, False, 'str2', True], where the output would be [3, 2, 1], as a boolean type appears first, and occurs three times in the list. A string appears next, and occurs twice in the list. Finally, an integer appears next, and occurs once in the list. """don't use any import, dictionaries, or dictionary methods or try-except statements.
# Create a list of tuplestuples = [("p", 1), ("q", 2), ("r", 3)]# Use enumerate() to iterate over the tuples and print the index and valuefor index, value in enumerate(tuples):print(index, value)This code will print the following output:0 p1 q2 r
Could you try to modify your code to get the output mentioned by you? Also, the output for the above function should be0 ('p', 1)1 ('q', 2)2 ('r', 3) Could you please confirm?
Your solutions can use:• the [] operator to get and set list elements (e.g., lst[i] and lst[i] = a)• the in and not in operators (e.g., a in lst)• the list concatenation operator (e.g., lst1 + lst2)• the list replication operator (e.g., lst * n or n * lst)• Python's built-in len, min and max functions, unless otherwise noted.Your solutions cannot use:• list slicing (e.g., lst[i : j] or (lst[i : j] = t)• the del statement (e.g., del lst[0])• Python's built-in reversed and sorted functions.• any of the Python methods that provide list operations, e.g., sum, append, clear, copy, count, extend, index, insert, pop, remove, reverse and sort• list comprehensions

using python language Use the function design recipe to develop a function named Fibonacci_sequence. The function takes an integer n. The function returns a list containing the Fibonacci sequence, up until the nth term. The Fibonacci sequence is defined as Fn = Fn-1 + Fn-2. For example, if n = 6, then the…

- *IN C++ A handy feature of lists in Python is that you can use negative indices to get at elements starting from the very end. For example, x[-1] returns the last element in x, x[-2] returns the penultimate element, etc. Implement a struct named "PythonicIntVector" in the files "PythonicIntVector.h" and "PythonicIntVector.cpp" that supports the push_back and at methods of a vector of ints. However, be sure to add the functionality of negative indices. Don't forget that the at method still should throw exceptions for invalid indices (just like in Python)!arrow_forwardB1.
