NameError: name 'current_time' is not defined

抱歉,我之前给出的示例代码有误。以下是一个修正过的示例代码,用于打印当前时间:
```python
import datetime
current_time = datetime.datetime.now().strftime("%Y-%m-%d %H:%M:%S")
print("当前时间:", current_time)
```
这段代码使用了Python中的datetime模块,通过调用`datetime.now()`函数获取当前时间,并使用`strftime()`函数将其格式化为年-月-日 时:分:秒的字符串格式。然后使用`print()`函数将其打印输出。请注意,这里的`current_time`是一个字符串变量。

NameError: name 'income_statement' is not defined
This error message indicates that the name 'income_statement' has not been defined or declared in the current Python environment.
To resolve this error, you need to define or declare the variable 'income_statement' before using it in your code. You can define it as an empty list, dictionary or any other data type depending on your use case.
Here's an example of defining 'income_statement' as an empty dictionary:
```
income_statement = {}
```
After defining the variable, you can use it in your code without getting the NameError.
NameError: name 'str_reverse' is not defined
This error occurs when you try to call a function or variable that has not been defined or declared in the current scope.
In this case, it seems that you are trying to call a function called 'str_reverse', but it has not been defined anywhere in your code. You need to define the function before you can call it.
Here is an example of how to define the str_reverse function that reverses a string:
```
def str_reverse(s):
return s[::-1]
```
Then you can call the function like this:
```
my_string = "hello world"
reversed_string = str_reverse(my_string)
print(reversed_string)
```
This should print out "dlrow olleh".
