How can I search for values in a .txt file in python?

I just need a little help with my code. I ask for name input and I try to make the code check if the input is in the user, but it always says that it's the user's first time.

name_file = open("NAME_DATA.txt", "r")

name = str(input("Hello, What is your first and last name?\n"))


if name in name_file:
  Clear()
  print("Good to see you again! It looks like you have used this before!")
  tm.sleep(3)
  name_file.close()
if name not in name_file:
  Clear()
  print("I see this is your first time using this software. Have fun!  Just a disclaimer, your 
  name will be added to the name_data.txt file, but we will never share anyones name!")
  tm.sleep(5)
  name_file = open("NAME_DATA.txt", "a")
  name_file.write(str(name) + "\n")
  name_file.close()

Please somebody help me with this!!

You should really consider using the with context manager when working with files, this way you do not need to worry about opening and closing file handles. Additionally I would be surprised if you do not get an error on the conditional block name not in name_file given you open the file with a different mode before closing it again. I would do something more like this

with open("NAME_DATA.txt", "r") as name_file:
    data = name_file.read()

name = str(input("Hello, What is your first and last name?\n"))

if name in data:
    Clear()
    print("Good to see you again! It looks like you have used this before!")
    tm.sleep(3)
else:
    Clear()
    print("I see this is your first time using this software. Have fun!  Just a disclaimer, your 
  name will be added to the name_data.txt file, but we will never share anyones name!")
    tm.sleep(5)
    with open("NAME_DATA.txt", "a") as name_file:
        name_file.write(str(name) + "\n")

As @Mike67 said in the comments before I could:

name_file = open("NAME_DATA.txt", "r").read()

Will read the file as text (string)

you can also use .readlines() to make a list from each line in the txt files for further processing

You need to read the text file.

Try this code:

name_file = open("NAME_DATA.txt", "r")
data = name_file.read()

name = str(input("Hello, What is your first and last name?\n"))
    
if name in data:
  Clear()
  print("Good to see you again! It looks like you have used this before!")
  tm.sleep(3)
  name_file.close()
else:  #if not name in data:
  Clear()
  print("I see this is your first time using this software. Have fun!  Just a disclaimer, your 
  name will be added to the name_data.txt file, but we will never share anyones name!")
  tm.sleep(5)
  name_file = open("NAME_DATA.txt", "a")
  name_file.write(str(name) + "\n")
  name_file.close()
