Here we iterate over all dictonaries in list. For every dictionary we iterate over its .items() and extract the key and value and then we construct a tuple for that with (key,)+val. Whether the values are strings or not is irrelevant: the list comprehension simply copies the reference ...
Write a Python program to convert a given list of dictionaries into a list of values corresponding to the specified key. Use a list comprehension and dict.get() to get the value of key for each dictionary in lst. Sample Solution: Python Code: # Define a function 'pluck' that takes a l...
