How to connect to MySQL using Python1. MySQL-pythonMySQL-python, also called MySQLdb, is the most popular driver for Python to connect to MySQL. Many frameworks are also developed based on this library. Unfortunately, it only supports Python2.x, and there are many prerequisites during installation. , because it is a library developed based on C. It is very unfriendly to install on the Windows platform and often fails. It is basically not recommended to use it now and will be replaced by its derivative version. #Precondition sudoapt-getinstallpython-devlibmysqlclient-dev#Ubuntusudoyuminstallpython-de
Using Python’s type functionThe type() function in Python is a commonly used function that returns the type of an object. In Python, everything is an object, including integers, floating point numbers, strings, lists, dictionaries, functions, etc. The type() function can help us obtain the type of an object so that we can judge, process, and operate it. The syntax of the type() function is very simple and can be called in the form of type(object). Among them, object is the object of the type to be obtained. Below, we use
From Beginner to Mastery: The Ultimate Guide to Exception Handling in Python1. Basics of Python exception handling What are exceptions? Exceptions are errors or unexpected conditions that occur during program execution. Exceptions can be caused by many reasons, such as syntax errors, runtime errors, resource errors, etc. Exception types There are many exception types built into Python. Common ones are: SyntaxError: syntax error, which usually exists when the code is written. NameError: Name error refers to an undefined name used in the program. TypeError: Type error refers to the incorrect type used in the program. ValueError: Value error refers to the use of inappropriate values in the program. ZeroDivisionError: zero division error, refers to
Use Python exception handling to make your code more elegantIn Python, the exception handling mechanism is a very important part of program development. It helps you catch and handle runtime errors to prevent program crashes. At the same time, the exception handling mechanism also allows you to write more robust and reliable code. In Python, exception handling is mainly implemented through try-except-finally statements. Among them, the try block contains the code that needs to be executed, the except block contains the code that catches the exception, and the finally block contains the code that will be executed regardless of whether an exception occurs. The following is a simple exception handling example: try: #Execute code that may cause exceptions result=1/0exceptZeroDivisionError:
