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...")
            sys.exit()

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

                print("There is nothing to do here yet!")
            else:

updated my code... everything is fixed :) i made functions

import time
import sys

login()

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

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

Organizing code into functions is always important for readability and also to be able to reuse parts of your code as your app gets bigger. Thank you for posting your updated code to share with others :)
