wall.append(row, column) TypeError: append() takes exactly one argument (2 given)

这个错误提示说明你在使用append()方法时提供了两个参数,而实际上这个方法只接受一个参数。可能是你想把一个元素添加到列表中,但是写法有误。
正确的写法应该是:wall.append((row, column)),把需要添加的元素放在一个元组中作为参数传递给append()方法。这样就可以把这个元组作为一个整体添加到列表中了。

TypeError: list.append() takes exactly one argument (2 given)
This error is raised when the `append()` method of a list is called with more than one argument. The `append()` method is used to add an element to the end of a list.
Example:
```
my_list = [1, 2, 3]
my_list.append(4, 5) # Raises TypeError: append() takes exactly one argument (2 given)
```
To fix this error, make sure that the `append()` method is called with only one argument.
Example:
```
my_list = [1, 2, 3]
my_list.append(4)
print(my_list) # Output: [1, 2, 3, 4]
```
TypeError: list.append() takes exactly one argument (3 given)
This error occurs when you try to pass more than one argument to the `append()` method of a list. The `append()` method only takes one argument, which is the item you want to add to the end of the list.
For example, if you have a list called `my_list` and you want to add the integers 1, 2, and 3 to the end of the list, you might try to do it like this:
```
my_list = []
my_list.append(1, 2, 3)
```
However, this will result in a `TypeError` because you are passing three arguments to the `append()` method instead of just one.
To fix this error, you need to call the `append()` method once for each item you want to add to the list:
```
my_list = []
my_list.append(1)
my_list.append(2)
my_list.append(3)
```
Now the integers 1, 2, and 3 will be added to the end of the `my_list` list, and you will not get a `TypeError`.
