TypeError: list.append() takes exactly one argument (4 given)
时间: 2023-09-10 09:15:08 浏览: 97
这个错误提示意味着您尝试在列表中使用 append() 方法时给了多个参数。请检查您的代码并确保在 append() 方法中只传递一个参数。例如,以下代码会导致类似的 TypeError:
```
my_list = []
my_list.append(1, 2, 3, 4)
```
而正确的写法应该是:
```
my_list = []
my_list.append(1)
my_list.append(2)
my_list.append(3)
my_list.append(4)
```

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`.
