AttributeError: 'str' object has no attribute 'isoformat'. Did you mean: 'format'?

This error occurs when you try to use the isoformat method on a string object, but it is not defined on strings. The isoformat method is defined on datetime objects, and it returns the string representation of the datetime object in the ISO format.
If you meant to format a string, you can use the format method instead. For example:
```
my_str = "Hello, {}!"
formatted_str = my_str.format("world")
```
If you meant to work with a datetime object, make sure you are creating or passing a datetime object to the isoformat method. For example:
```
import datetime
my_datetime = datetime.datetime.now()
isoformat_str = my_datetime.isoformat()
```

AttributeError: DataFrame object has no attribute append . Did you mean: _append ?
This error occurs when you try to call the `append` method on a Pandas DataFrame object, but the object does not have an `append` attribute.
One possible reason for this error is that you are trying to append a DataFrame to another DataFrame using the `append` method, but you are not using it correctly. In Pandas, the `append` method does not modify the original DataFrame, but instead it returns a new DataFrame that contains the rows from both DataFrames. Therefore, you need to assign the result of the `append` method to a new variable or to the original DataFrame, like this:
```
df1 = pd.DataFrame({'A': [1, 2], 'B': [3, 4]})
df2 = pd.DataFrame({'A': [5, 6], 'B': [7, 8]})
df3 = df1.append(df2)
```
In this example, `df3` will contain the rows from both `df1` and `df2`.
If you are still getting the AttributeError, it's possible that the DataFrame object you are trying to append to does not have an `append` attribute. In this case, you can try using the `_append` attribute instead, which is a private method that is used internally by Pandas. However, be aware that using private methods may not be supported in future versions of Pandas and may cause unexpected behavior.
```
df1._append(df2)
```
AttributeError: 'str' object has no attribute 'forrmat'. Did you mean: 'format'?
AttributeError: 'str' object has no attribute 'forrmat'. Did you mean: 'format'?
这个错误是由于您在代码中使用了错误的方法名。正确的方法名是'format'而不是'forrmat'。您可以将错误的方法名更正为'format'来解决这个错误。
