Concurrent and Parallel Programming in Python - Threading in Python

This video tutorial introduces threading in Python, using PyCharm as the coding environment. It covers setting up a basic program with functions to calculate the sum of squares and to sleep for a specified time. The tutorial demonstrates running the program sequentially and then introduces concurrency using threading. It explains how to manage threads with join and daemon flags, highlighting the differences in execution and performance.

Which coding environment is preferred by the instructor for handling multiple files?

• Spider

• Jupyter Notebooks

• PyCharm

• Visual Studio Code

What is the purpose of the 'pass' statement in the main function?

• To define a placeholder for future code

• To execute the function immediately

• To terminate the program

• To import necessary modules

What does the 'calculate sum of squares' function do?

• Calculates the square root of a number

• Calculates the sum of squares up to a given number

• Calculates the factorial of a number

• Calculates the sum of cubes up to a given number

How is the execution time of a function measured in the program?

• Using a stopwatch

• Using the time module

• Using a timer function

• Using a delay function

What is the main advantage of using threading in the program?

• It reduces the code size

• It allows concurrent execution of tasks

• It simplifies debugging

• It increases the program's memory usage

What must be done to initiate a thread in Python?

• Call the thread's initialize method

• Call the thread's execute method

• Call the thread's start method

• Call the thread's run method

What does the join method do in threading?

• It blocks execution until the thread finishes

• It terminates the thread

• It pauses the thread

• It starts the thread

What is the effect of setting a thread as a daemon?

• The thread runs with higher priority

• The thread does not need to finish for the program to exit

• The thread runs in the background indefinitely

• The thread cannot be joined

How does the placement of the join method affect program execution?

• It alters the thread's execution speed

• It determines when the program waits for thread completion

• It changes the thread's priority

• It modifies the thread's memory usage

What happens to daemon threads when the main program finishes?

• They are converted to non-daemon threads

• They are terminated

• They are paused

• They continue running
