Python 2.7.16 - Name not defined

I have the following code, however when I run it, the variable stored under employee_name is stated as "Name '[name inputted]' is not defined.
I've tried to comment it out, and the issue just arises with another line. Employee_num needs to be a string, as putting it as an integer claims it to not be iterable.
Can anyone help?

Budget tracker program not working in Linux

I am trying to improve this program. I am working with Linux. I want to add a menu function where the user can pick an option and based on the option call the respective function, but the program is not working, when I run it in the Terminal it doesn't do anything and doesn't show any errors. Please, I need help to solve the problem and make the program works. Thanks!
Here's what I have so far, still there are some functions that need to develop:

Trying to compare two strings in python

I even used print statements to check if y.name and favourite were the same when checking this and they were yet it still wasn't entering the if statement when using
if y.name == favourite
or
if favourite ==y.name
I'm super confused as to why that is since I thought this was just a standard equality check (The beginning of the code is mostly set up, just included it for context in the case that there was a problem there and not the if statement). Thank you in advance!
class Anime(object):
name: str = ""
year_aired = 0
genre1: str = ""
def __init__(self, name, genre1, year_aired):
self.name = name
self.genre1 = genre1
self.year_aired = year_aired
def _make_anime(name, genre1, year_aired):
anime = Anime()
return anime
animelist = input("Please enter a file with a list of anime\n")
animel = open(animelist, "r")
nolines = animel.readlines()
animearr = []
numanime = -1
for i in nolines:
if i.find("*") != -1:
animearr[numanime].genre1 = i
else:
k = Anime("","", 2018)
k.name = i
animearr.append(k)
numanime += 1
favourite = input("Please enter your favourite anime\n")
favgenre = ""
for y in animearr:
if y.name == favourite:
favgenre = y.genre1
print(favgenre)

I think you should add strip.("\n") before you compare two string.
class Anime(object):
name: str = ""
year_aired = 0

if i.find("*") != -1:
animearr[numanime].genre1 = i
else:

k.name = i
animearr.append(k)
numanime += 1
favourite = input("Please enter your favourite anime\n")
favgenre = ""
for y in animearr:
if y.name == favourite.strip("\n"):

Create a list of a class as an attribute of a second class in Python

I have an intro class in Python where part of the instructions are:
(2) Build the ShoppingCart class with the following data attributes and related methods. Note: Some can be method stubs (empty methods) initially, to be completed in later steps.
Parameterized constructor which takes the customer name and date as parameters
Attributes
customer_name (string) - Initialized in default constructor to "none"
current_date (string) - Initialized in default constructor to "January 1, 2016"
cart_items (list)
Methods
add_item()
Adds an item to cart_items list. Has parameter ItemToPurchase. Does not return anything.

Can anyone tell me what I am doing incorrectly?

class ShoppingCart:
def __init__(self, name="none", date="January 1, 2016"):
cart_items = []
_customer_name = name
_current_date = date
These are all local variable. If you want them to be attributes of the instance, you have to explicitly refer to self:
class ShoppingCart:
def __init__(self, name="none", date="January 1, 2016"):
self.cart_items = []
self._customer_name = name
self._current_date = date

Saving objects to a list python; List not updating for some reason?

Alright so what I am trying to do is to get objects to save in list form when a user creates a NoteSet. It appends the objects to the list db properly when I input NoteSet('ex','example',True). I made a function called makeNewNoteSet() and it seems to be working correctly but it doesnt append to the db list. I can not figure out why.
import sys
import datetime
import pickle
notesets = []
db = []
def save():
global db
filename = "notesets.dat"
file = open(filename, "wb")
if file == None:
print("There was an error creating your file")
return
pickle.dump(db, file)
file.close()
print("Saved words to ",filename)
def load():
global db
filename = "notesets.dat"
file = open(filename, "rb")
db = pickle.load(file)
print("There are ",len(db)," Note Sets")
file.close()
class NoteSet:
nextseqNum = len(db)+2
def __init__(self,name,description,hidden):
global db
self.seqNum = NoteSet.nextseqNum
self.name = name
self.description = description
self.dateCreated = datetime.date.today()
self.hidden = hidden
self.notes = list()
NoteSet.nextseqNum += 1
print(self)
notesets.append(self)
notelist = [self.seqNum,self.name,self.description,self.dateCreated,self.hidden,self.notes]
print(notelist)
db.append(notelist)
NoteSet.nextseqNum += 1
def __str__(self):
printstr = str(self.seqNum),self.name,self.description,str(self.dateCreated)

self.text = text
self.dateCreated = str
self.dateRead = str
self.description = str
self.category = str
self.priority = int
self.hidden = bool
self.seqNum = Note.nextseqNum
Note.nextseqNum += 1
def main():

input("[Press return to see main menu]")
main()
def listAllNoteSets():
num = 0
for row in db:
print('#',db[num][0],' ',db[num][1],'----',db[num][2])

input("[Press return to see main menu]")
main()
def makeNewNoteSet():
num = 0

for row in db:
if name == db[num][1]:
print("That note set has already been created")
makeNewNoteSet()
description = input("Describe your note set briefly --- ")

response = input("Enter the number assosciated with the noteset you would like to access")
print("Note set #",response," was selected")
main()

After you add a new note in makeNewNoteSet(), you call main() which calls load() which overwrites the in-memory copy of the database you just changed. You probably want to call save() somewhere in there.
