I need a Python program that will do custom executions for attribute, syntax, name, index, key, and module errors using my operation_synthesis() function, which opens a file as red_3. For the excepts, it needs to state the error in plain English, then close the file, not break.

Sure! The code below uses a `try`/`except` block to accomplish that. It first tries the function `operation_synthesis()`, then returns a custom message for each type of error. For example, if an AttributeError occurs, the `except AttributeError` block will print the message, `"A method or function was called on an invalid data type."` and close the file by using `.close()` on the `red_3` file variable. By using `as err` on the `except` statements, you can bind the exception to a variable called `err` so you can access details about it.

```
# Try the function
try:
    operation_synthesis()
# Except for each type of error and close the file
except AttributeError as err:
    print("A method or function was called on an invalid data type.")
    red_3.close()
except SyntaxError as err:
    print("There was a syntax error in the code.")
    red_3.close()
except NameError as err:
    print("A variable was used before definition.")
    red_3.close()
except IndexError as err:
    print("There was an attempt to access an item that was not present in the list.")
    red_3.close()
except KeyError as err:
    print("A key was not found in a dictionary.")
    red_3.close()
except ModuleNotFoundError as err:
    print("An import failed because the module could not be found.")
    red_3.close()
```
