The video tutorial explains how to group dictionaries based on whether individuals are adults or minors using Python's itertools groupby function. It covers importing the necessary module, defining a lambda function to select the grouping key, and implementing the logic to iterate over the groups and print the names of individuals in each group. The tutorial concludes by demonstrating the output of the grouping process, showing how to label and list adults and minors separately.

What is the primary purpose of using the 'groupby' function from the 'itertools' module?

• To sort a list of dictionaries

• To merge multiple dictionaries into one

• To filter out dictionaries with a certain value

• To group dictionaries based on a specific key

Which function is used to select the key for grouping in the 'groupby' method?

• A predefined function

• A lambda function

• A map function

• A filter function

What is the role of the lambda function in the grouping process?

• To sort the dictionaries

• To select the key for grouping

• To filter out unwanted dictionaries

• To merge dictionaries

How are the groups labeled in the final output?

• By their index in the list

• By the number of elements in each group

• By the length of the names in each group

• As 'Adult' or 'Minor' based on the grouping key

What method is used to print the names of individuals in each group?

• Using a recursive function

• Using a while loop

• Using a for loop with list comprehension

• Using a simple print statement
