Popleft

Operation that removes and returns the first element from a data structure.

Popleft refers to the operation of removing and returning the first element from a data structure, typically used in programming contexts involving queues or dequeues.

Popleft is a method name derived from 'pop' (to remove) and 'left' indicating removal from the left side of a data structure.

Popleft is like taking the first toy from a line of toys - it removes that toy and gives it to you.

Popleft is often used in algorithms to process data from the beginning
It's a core operation in Python's collections
deque
Some languages offer popleft as an alternative to shifting elements when removing the first element

What does popleft do? It removes and returns the first element from a data structure
How is it different from pop()? Popleft removes from the beginning, while pop typically removes from the end
What data structures use popleft? It's commonly used with double-ended queues (deque)
