I really enjoyed this Video. While using MySQL I did observe if a record doesn't exist in DB and we try to delete it, it doesn't actually throw an error or alert that the user doesn't exist. But I managed it through Python. Below is an example of Insert def list_user_id(self): query = "select user_id from user" cur = self.con.cursor() cur.execute(query) record = [item[0] for item in cur.fetchall()] return record choice=int(input("enter your choice of 1 2 3 4 or 5 from above menu ")) if choice == 1: user_list = helper.list_user_id() user_id=int(input("Enter the user_id ")) if user_id not in user_list: name=input("Enter the name ").capitalize() phone=input("Enter the phone ").capitalize() helper.insert_user(user_id,name,phone) else: print("user {} already in database, please use update instead".format(user_id))
If you facing this type of error when connecting SQL database with python error like"Traceback(most recent call last): ....Just run this command "pip install mysql-conncetor-python"). It worked for me..
I'm from Bangladesh. First of all, this is changed my mind for web development. Everytime I'm heard about python is not connect mysql database. You save my life.. Thanks a lot sir. And out of topic, can you tell which VSCode theme and extension you use in this video

I made a program for username and password with pycharm and xamp database ... Every username and password entered is registered in database. What command i should use so that if user inputs same username that's already been registered in the database , it shows error with message username already in use try different username
i wrote the same code till 28:00, yet i am only getting "created" as the output. the output should not defer with the IDE used. I usually write on pycharm yet I did not receive the same output as in the video.
why I am facing this issue self is aleady define why this error is coming File "c:\Users\Dell\Desktop\python with mysql\main.py", line 3, in class DBHelp(): File "c:\Users\Dell\Desktop\python with mysql\main.py", line 11, in DBHelp cur = self.con.cursor() NameError: name 'self' is not defined
Bro this was good, but you could have wrapped everything in 25 min, you were telling lot of obvious things which were not necessary to be explicitly explained.
