get() takes from 1 to 2 positional arguments but 3 were given

get()是Python中的一个内置函数,用于从字典中获取指定键的值。根据你提供的错误信息,"get()"函数接受1到2个位置参数,但是你传递了3个参数。
通常情况下,"get()"函数接受两个参数:键和可选的默认值。如果字典中存在指定的键,则返回对应的值;如果不存在,则返回默认值。例如:
```
my_dict = {"key1": "value1", "key2": "value2"}
result = my_dict.get("key1", "default_value")
print(result) # 输出: value1
```
在你的情况下,你可能在调用"get()"函数时传递了额外的参数,导致了错误。请检查你的代码,确保只传递了一个或两个参数给"get()"函数。

raw_input() takes from 1 to 2 positional arguments but 3 were given
This error message indicates that the function raw_input() was called with three arguments, but it only accepts one or two arguments.
The most common cause of this error is passing too many arguments to the function. For example, if you try to call raw_input() with three strings as arguments, like this:
raw_input("Enter your name: ", "Enter your age: ", "Enter your gender: ")
You will get the "takes from 1 to 2 positional arguments but 3 were given" error message, because raw_input() only accepts one or two arguments.
To fix this error, you need to pass the correct number of arguments to the function. In the case of raw_input(), you should only pass one argument if you want to display a prompt message, like this:
name = raw_input("Enter your name: ")
Or you can call the function without any arguments, like this:
name = raw_input()
ClientSession.get() takes 2 positional arguments but 3 were given
This error message typically occurs when you are trying to call the `get()` method of a `ClientSession` object with too many arguments. `ClientSession.get()` only takes one positional argument, which is the URL you want to fetch.
Double-check your code to ensure that you are passing in the correct number of arguments to `get()`. If you are still having trouble, try posting your code so that others can help you debug the issue.
