str' object is not callable- tic_tac_toe- Pytnon

Question

I try to make a tic tac toe game and I get:

'str' object is not callable

as error. No idea what to do.

from IPython.display import clear_output 

def display_board (board):

    clear_output() 
    print (' ' + board [7] + '|' + board [8] + '|' + board[9])
    print (' ' + board [4] + '|' + board [5] + '|' + board[6])

    while marker != "X" and marker != "O": 

        marker = input ('Igralec 1: izberi X ali O: ').upper()
    
    if marker == 'X':
        return ('X', 'O')
    else:
        return ('O', 'X')

TypeError: 'str' object is not callable

Answer 1

This line of code:

print= (turn+ ' je prvi igralec!')

Should be written like this:

print(turn+ ' je prvi igralec!')

You can find what goes wrong with the error description hints ;)

Answer 2

You have the typo = in print(), the fix would be:

print(turn + ' je prvi igralec!')

to prevent such cases install the linter, like flake8 or pylint, they could help you to improve your code. Also check the black formatting tool to improve readability.
