Question

im试图从python文件中逐行加载单位数字，此代码会显示错误消息：

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

此处是源代码：（main.py）

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

environment.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)

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

关于load_map函数：split无需遍历字符串。将这样的地图存储到2D列表中也很有意义。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)
