When calling an OOP function, TypeError: takes 1 positional argument but 2 were given. How do I fix this?

Question

我正在尝试在 python 中制作文字游戏。但是，当我运行以下代码时，我得到 TypeError: print_guess() takes 1 positional argument but 2 were given.

from colorama import init, Fore, Back, Style

class game:
    def __init__(self, guess, answer):
    self.guess = guess
    self.answer = answer

    def get_eval(self): # shortened version of full get_eval() function. 
    output = [0,0,0,0,0]
    for letter in range(5):
        if self.answer[letter] == self.guess[letter]: # check if correct letter is in the correct place.
        output[letter] = 2
    return tuple(output)

    def print_guess(self):
    colors = ['BLACK', 'YELLOW', 'GREEN']
    for i in range(5):
        colour = getattr(Back, colors[self.get_eval(self)[i]]) # TypeError: get_eval() takes 1 positional argument but 2 were given
        print(Style.BRIGHT + Fore.WHITE + colour + self.guess[i].upper(), end=' ')

game_dis = game('guess', 'words')
game_dis.print_guess(game_dis.guess) # TypeError: print_guess() takes 1 positional argument but 2 were given`

Answer 1

您将“self”参数作为方法的参数。这基本上是 class 对象的实例。这是一个您不必自己通过但自动通过的论点。所以当你像你一样给出一个额外的参数时，你给出了两个。

将您的代码更改为：

game_dis.print_guess()
