select_kv_pairs

This is a short Python script demonstrating how to extract select key:value pairs from a dictionary.

Script Operation

We start with the initial, unfiltered kv_pairs dictionary.

  kv_pairs = {'a':1, 'b':2, 'c':3, 'd':4, 'e':5, 'f':6, 'g':7, 'h':8, 'i':9, 'j':10}

Next, we define a list of keys for the key:value pairs that we want to extract.

  preferred_keys = ['a', 'c', 'e', 'g', 'i']

Looping through the list generates a new dictionary with only the select key:value pairs that we wanted.

  select_kv_pairs = {key:kv_pairs[key] for key in preferred_keys}

The resulting select_kv_pairs dictionary is shown below.

  {'a':1, 'c':3, 'e':5, 'g':7, 'i':9}
