"This example shows how to print logs to file. It shows how to use the `FileCallbackHandler`, which does the same thing as [`StdOutCallbackHandler`](/docs/modules/callbacks/#get-started), but instead writes the output to file. It also uses the `loguru` library to log other outputs that are not captured by the handler."

"LangChain provides the `FileCallbackHandler` to write logs to a file. The `FileCallbackHandler` is similar to the [`StdOutCallbackHandler`](/docs/modules/callbacks/), but instead of printing logs to standard output it writes logs to a file.\n",

"We see how to use the `FileCallbackHandler` in this example. Additionally we use the `StdOutCallbackHandler` to print logs to the standard output. It also uses the `loguru` library to log other outputs that are not captured by the handler."
