python - 从Python文件中加载文本

Question

我试图从 python 中的文件中逐行加载个位数，此代码会出错:

line 27, in <module>
environment.environment1.load_map(environmentVector)
TypeError: load_map() takes 1 positional argument but 2 were given

这是源代码:(main.py)

environmentVector = []
environment.environment1 = environment.environment(160, 100, 32, 32)
environment.environment1.load_map(environmentVector)

环境.py:

    def load_map(environmentVector):
        string = ''
        with open('map.txt', 'r') as f:
            for line in f:
                string = f.readline()
                row = []
                for character in string:
                    if character == '0':
                        pass
                    elif character == '1':
                        environmentVector.append(environment)

Answer 1

首先，如果load_map是类的方法，它需要采用的第一个参数是self。添加 self，或使用 @staticmethod 将 load_map 标记为静态方法，请参阅 this .

关于您的load_map函数:分割它而不是迭代字符串。将这样的 map 存储到 2D 列表也是有意义的。试试这个:

def load_map(self, environmentVector):
    with open('map.txt', 'r') as f:
        for line in f:
            nums = list(map(int, line.split()))
            environmentVector.append(nums)
