Get signal names from numbers in Python

Get signal names from numbers in Python

If you have a numeric signal value and you want to retrieve the corresponding signal name or description in Python, you can use a dictionary (or another data structure) to map the numeric values to their corresponding names. Here's an example of how you can achieve this:

# Define a dictionary that maps signal numbers to their names signal_mapping = { 0: "No Signal", 1: "Low Signal", 2: "Medium Signal", 3: "High Signal" } # Input signal value signal_value = 2 # Get the signal name for the given value signal_name = signal_mapping.get(signal_value, "Unknown Signal") # Print the result print(f"Signal value {signal_value} corresponds to: {signal_name}")

In this example, we define a dictionary signal_mapping that associates numeric signal values with their corresponding names. We then use the get() method of the dictionary to retrieve the name for a given signal value. If the signal value is not found in the dictionary, it defaults to "Unknown Signal."

You can customize the signal_mapping dictionary to include the specific signal values and names relevant to your application. This approach allows you to easily map numeric signals to their names and retrieve them in a readable and maintainable way.
