removing item

[pastakipp]

I have a question, is it possible to remove a string in a list, if the same string also exists in a file, by using a code?

If yes, how can i do that?

Open the file
Until you reach end of file, read a string
See if string is in the list
If yes, remove the string from the list

What have you done so far?

Hello, I have a list: list = ['1', '2']
in my txt file i have only written the number 2 in the first line.

so i actually want to make a code that reads the txt file, and if the string in the txt file also excists in the list i made, i want it to delete it out of the list.. so if i print list after it removed it should print out only ['1']

Solve this problem first.
a = [1, 2, 3, 4, 5]
From a remove 2

Once you can solve that problem solve this problem:
a = [1, 2, 3, 4, 5]
b = [2, 4, 6]
From a remove any number that is in b.

Once you solve that problem solve this problem:
Make a list of all numbers contained in file b.

And finally:
a = [1, 2, 3, 4, 5]
From a remove any number that is in file b.
