Create a Python programme that inputs a list of strings into a dynamic array. Allow the user to input as many pieces as they like, and then to remove them as necessary?

Given an initialized  two-dimensional list  X and two variables i and j. Write an expression to assigne an float value from the keyboard  to the i-th element of the j-th row. code in python

Write a Python program that removes the duplicates from a list. Use inputs a list of integers from the user, and removes the duplicate list elements, plus outputs their min and max values. (the program should have more than 1 function and leave comments as explanations of what does the code does). Ex (in pictures below):

Create a Python programme that reads a string list from the user and stores it in a dynamic array. The user should be able to insert as many pieces as they want and remove them as needed. Exemplify each sentence, please.

Looking for python guidance for the code comments.  Write a program that replaces words in a sentence. The input begins with word replacement pairs (original and replacement). The next line of input is the sentence where any word on the original list is replaced. Ex: If the input is: automobile car manufacturer maker children kids The automobile manufacturer recommends car seats for children if the automobile doesn't already have one. the output is: The car maker recommends car seats for kids if the car doesn't already have one.    Looking for python guidance for the code comments.
