Python | Transcribing dictionary key

Creating a new dictionary where the keys are some transformation or transcription of the original keys, then you can achieve this using dictionary comprehensions.

For instance, let's say we have a dictionary:

data = { "name_1": "Alice", "name_2": "Bob", "name_3": "Charlie" }

And you want to transcribe the keys by removing the "name_" prefix, resulting in:

{ "1": "Alice", "2": "Bob", "3": "Charlie" }

You can use a dictionary comprehension:

transcribed_data = {k.split('_')[1]: v for k, v in data.items()} print(transcribed_data)

Here's a step-by-step breakdown:

  1. We use k.split('_')[1] to split the key at the underscore (_) and then select the second part (index 1). This essentially removes the "name_" prefix.
  2. The {k.split('_')[1]: v for k, v in data.items()} creates a new dictionary with the transcribed keys and their corresponding values.

Run the code, and you will get the desired output:

{ "1": "Alice", "2": "Bob", "3": "Charlie" }

You can modify the transcription logic in the dictionary comprehension to fit any specific key transformation requirements you might have.
