Python PracticeFunctions1. Write a function that takes in a list and returns a new list that has the elements of theparameter in reverse order2. Write a function to return the index of the maximum element in a list3. Write a function that takes in a list returns a new list with only the odd elements from theparameter list.4. Write a function that takes in two lists. Each parameter represents a point, e.g., [1,1]. Returnthe Euclidean distance between the two points.5. Write a function that takes in a filename. Open the file, and return a list where each elementis a line from the file.6. Write a function that takes in a filename and a list. Write the contents of the list to the file.Each element should be on its own line in the file.Classes1. Create a class titled BankAccount.2. Create a constructor that takes an ID parameter and initial deposit amount parameter. Theconstructor should set an 'id' member to the ID parameter and set the 'balance' member tothe initial deposit parameter.3. Create the following methods for the BankAccount class:1. deposit. This method should take a deposit amount parameter. Add the parameter to the'balance' member.2. withdraw. This method should take a withdrawal amount parameter. Subtract theparameter from the BankAccount. Make sure that the account has a balance greater thanor equal to the withdrawal amount.4. All methods should return the balance member.5. Outside of the class, create two BankAccount objects.6. Call your methods with the objects you created and print out the results.

3. Define a function in Python that takes a list as the parameter and returns True if the list contains a 2-digit positive number. Otherwise, the function should return False.
should be in python: write a function that receives a list as its only parameter. Inside the function remove all the duplicate items from the list and returns a new list and the input should be given by user. For Example: If we call the function with [“dad”, “aunt”, “mom”, “sister”, “mom”] as its user input, the returned value should be [“dad”, “aunt”, “mom”, “sister”]. The order of the items inside the returned list does not matter.

Python Programming: 2D list The Lo Shu Magic Square is a grid with 3 rows and 3 columns that contains the numbers 1 through 9 exactly. The sum of each row, each column, and each diagonal all add up to the same number. In a program, you can simulate a magic square using a two-dimensional list. Write a function that accepts a two-dimensional list as an argument and determines whether the list is a Lo Shu Magic Square. Test the function in a program. 4 9 2 3 5 7 8 1 6 To test the program, send in two two-dimensional lists: one is a Lo Shu Magic Square, the other is not.
