i have a computer science project and i can’t find anywhere how to figure this out. I need python to ask for input and if input is equal to a text file then it moves onto next input if it’s the same. If not it repeats the question: “please enter your name” so far I've got:

Player_1 = input(“please enter your name”)

Then need what I've said above. The text file only needs to contain two names. I am relatively new to python, hope someone can help.

    As a simple tip for your coding problem, try reading the lines from the file at the start and saving them in a data structure before you even check for user input. – Chris Oct 10 '18 at 14:02

Your text file "filename.txt" should use a symbol to separate names.

Let's say a comma, so your file should look like this:

filename.txt: Name1,Name2

You could use:

txt=open("filename.txt",'r').read()

to get your file content as string.

namesList=txt.split(',')

to get a list of the names in the file: 

["Name1","Name2"]

then a loop to check inputs of the user:

userEntry=''
while userEntry not in namesList:
    userEntry=input("please enter your name")

At the end, userEntry is equal to one of the two names in your file.
