You are given a code snippet in Python that prints an informational message based on a command provided as a property. Your task is to write a function that takes the command as input and returns the corresponding informational message.

Implement a function `get_info_msg(cmd: str) -> str` that takes a string `cmd` as input and returns the informational message based on the command. The function should return the following messages for each command:

- `"info"`: "This python snippet is triggered by the 'cmd' property.\r\nAny command line may be triggered with the 'cmd' property.\r\n"
- `"help"`: "This python snippet provides information based on the 'cmd' property.\r\nUse the 'cmd' property to obtain information for different commands.\r\n"
- `"about"`: "This python snippet provides information about its functionality.\r\nUse the 'cmd' property to trigger different commands.\r\n"
- `"default"`: "Invalid command! Please try using a valid command such as 'info', 'help', or 'about'.\r\n"

You can assume that the input command will always be one of the above four.

Sure, here's how you can define the `get_info_msg` function using Python 3.6:

```python
def get_info_msg(cmd: str) -> str:
    info_dict = {
        "info": "This python snippet is triggered by the 'cmd' property.\r\nAny command line may be triggered with the 'cmd' property.\r\n",
        "help": "This python snippet provides information based on the 'cmd' property.\r\nUse the 'cmd' property to obtain information for different commands.\r\n",
        "about": "This python snippet provides information about its functionality.\r\nUse the 'cmd' property to trigger different commands.\r\n",
        "default": "Invalid command! Please try using a valid command such as 'info', 'help', or 'about'.\r\n"
    }
    return info_dict.get(cmd, info_dict["default"])
```

In this function, the `dict.get()` method is used to retrieve the corresponding information from the `info_dict` dictionary based on the provided `cmd`. If no such key exists in the dictionary (i.e., if `cmd` is not equal to "info", "help", "about", or "default"), the default message is returned.

This function can be used in the code snippet as follows:

```python
def my_function(cmd):
    message = get_info_msg(cmd)
    # Use the message as needed
    print(message)
```

In this example, the `get_info_msg` function is called with the `cmd` property as a parameter, and the returned message is printed.

Here's the Python function `get_info_msg(cmd: str) -> str` that meets the described requirements:

```python
def get_info_msg(cmd: str) -> str:
    info_msg = {
        "info": "This python snippet is triggered by the 'cmd' property.\r\nAny command line may be triggered with the 'cmd' property.\r\n",
        "help": "This python snippet provides information based on the 'cmd' property.\r\nUse the 'cmd' property to obtain information for different commands.\r\n",
        "about": "This python snippet provides information about its functionality.\r\nUse the 'cmd' property to trigger different commands.\r\n",
    }

    return info_msg.get(cmd, "Invalid command! Please try using a valid command such as 'info', 'help', or 'about'.\r\n")
```

This function uses a dictionary `info_msg` storing the messages for the given commands ("info", "help", and "about"). By using the `dict.get(key[, default])` method, if the provided command exists in the dictionary, the corresponding message will be returned; otherwise, the default message will be returned.
