ComfyUI Node: Text Dictionary Get

Text Dictionary Get:

The Text Dictionary Get node is designed to retrieve the value associated with a specified key from a given dictionary. This node is particularly useful when you need to extract specific information from a dictionary structure, which is a common data format in various applications. By providing a key, the node will return the corresponding value, or a default value if the key is not found. This functionality is essential for tasks that involve dynamic data retrieval and manipulation, making it a valuable tool for AI artists who work with complex data sets and need to streamline their workflows.

Text Dictionary Get Input Parameters:

dictionary

The dictionary parameter is the main input for this node, where you provide the dictionary from which you want to retrieve a value. This parameter accepts a dictionary data type (DICT). The dictionary should contain key-value pairs, where the keys are strings, and the values can be of any data type. This parameter is required for the node to function.

key

The key parameter specifies the key whose value you want to retrieve from the dictionary. This parameter accepts a string (STRING) and is required. The key should match one of the keys in the provided dictionary. If the key is not found in the dictionary, the node will return the value specified in the default_value parameter.

default_value

The default_value parameter is an optional input that specifies the value to return if the specified key is not found in the dictionary. This parameter accepts a string (STRING) and has a default value of an empty string (""). This allows you to handle cases where the key might not exist in the dictionary gracefully.

Text Dictionary Get Output Parameters:

TEXT_TYPE

The output parameter of this node is of type TEXT_TYPE. It returns the value associated with the specified key in the dictionary as a string. If the key is not found, it returns the default_value provided. This output can be used in subsequent nodes for further processing or display.

Text Dictionary Get Usage Tips:

• Ensure that the dictionary provided contains the key you are looking for to avoid relying on the default value.
• Use the default_value parameter to handle cases where the key might not exist, ensuring your workflow does not break.
• Combine this node with other dictionary manipulation nodes to create complex data retrieval and processing pipelines.

Text Dictionary Get Common Errors and Solutions:

KeyError: 'key'

• Explanation: This error occurs when the specified key is not found in the dictionary and no default value is provided.
• Solution: Ensure that the key exists in the dictionary or provide a default_value to handle missing keys.

TypeError: 'NoneType' object is not subscriptable

• Explanation: This error occurs when the dictionary input is not properly provided or is None.
• Solution: Verify that the dictionary input is correctly passed to the node and is not None.

ValueError: dictionary update sequence element #0 has length 1; 2 is required

• Explanation: This error occurs when the input provided is not a valid dictionary.
• Solution: Ensure that the input is a properly formatted dictionary with key-value pairs.
