How do I make my code jump back to a previous line?

[trueriver]

I'm just coding something for fun right now and I'm stuck on looping. I'm using a while loop that only runs if my variable is 0. Right now, I set the variable to 0 but the code was after the loop. How do I fix this?

import time
import sys

#Global Variables
firstTime = True
loggedIn = False
incorrectLogin = True
admin = False
n = 0
n1 = 0


#Create login if firstTime is True
if firstTime is True:
    print("Welcome new user!")
    time.sleep(1)
    print("It looks like it's your first time using this program!")
    time.sleep(1.5)
    User = input("Please create a user: ")
    User_password = input("Please create a password: ")
    time.sleep(1)
    firstTime = False

#Cosmetic
print("Please log in")
time.sleep(1)

#Login code
while n == 0:
    if incorrectLogin is True:
        User_input = input("Please input user: ")
        if User_input == User:
            User_password_input = input("Please input password: ")
            #int(User_password_input)
            if User_password_input == User_password:
                print("Welcome, " + User + "!")
                loggedIn = True
                incorrectLogin = False
                n += 1
            else:
                print("Incorrect Password!")
                incorrectLogin = True
                loggedIn = False
        else:
            print("Incorrect User!")
            incorrectLogin = True
            loggedIn = False

#If want to set User as admin
askAdmin = input("Would you like to set, "+ User + " as admin? (Y/n) ")
if askAdmin.lower() in ["Y", "y"]:
    adminPass = input("Please set up a admin password: ")
    print("Setting "+ User + " as admin...")
    time.sleep(1)
    print("Done!")
    User_admin = User
    admin = True
    n1 += 1
elif askAdmin.lower() in ["N", "n"]:
    print("Skipping...")
    time.sleep(1)
    print("No admin on system.")
    admin = False
    n1 += 1

#When the user is logged in
while n1 == 1:
    if loggedIn == True:
        sysInfo = input("1. Who is using the system" \
        " 2. Shutdown"
        " 3. Is there an admin"
        " 4. Change User password"
        " 5. Admin panel"
        " 6. Log out")
        if sysInfo.lower() in ["exit", "Exit", "EXIT"]:
            sys.exit()
        elif sysInfo.lower() == "1":
            print(User)
        elif sysInfo.lower() == "2":
            print("Shutting down...")

                if askAdminPass != adminPass:
                    print("Incorrect Password!")
                else:
                    newUserPasswordWAdmin = input("Please enter new password: ")
                    User_password = newUserPasswordWAdmin
                    time.sleep(1)

login()

    if sysInfo.lower() in ["exit", "Exit", "EXIT"]:

since sysinfo is now lower(), it will never be equal to "Exit" or "EXIT"
