Starting from today, I will update a python function every day, along with examples and points to note when using the function. I named this function topic "Daily Lecture on Python Functions". I hope everyone will support it. Haha
Starting below, today’s function is abs()
First read the official English document explanation
abs(x)
Return the absolute value of a number. The argument may be a plain or long integer or a floating point number. If the argument is a complex number, its magnitude is returned.
Detailed explanation:
returns the absolute value
The parameter can be: negative number, positive number, Floating point number or long integer
Example:
abs(-1.2) #返回 1.2 abs(1.2) #返回 1.2 abs(-11216.5) #返回 11216.5 abs(11216.5) #返回 11216.5
Note: The parameter can be a negative number or a positive number. Only the absolute value will be taken and no rounding will be done.

The basic syntax for Python list slicing is list[start:stop:step]. 1.start is the first element index included, 2.stop is the first element index excluded, and 3.step determines the step size between elements. Slices are not only used to extract data, but also to modify and invert lists.

In Python, you can use for loops, enumerate and list comprehensions to traverse lists; in Java, you can use traditional for loops and enhanced for loops to traverse arrays. 1. Python list traversal methods include: for loop, enumerate and list comprehension. 2. Java array traversal methods include: traditional for loop and enhanced for loop.

The article discusses Python's new "match" statement introduced in version 3.10, which serves as an equivalent to switch statements in other languages. It enhances code readability and offers performance benefits over traditional if-elif-el

Exception Groups in Python 3.11 allow handling multiple exceptions simultaneously, improving error management in concurrent scenarios and complex operations.

Function annotations in Python add metadata to functions for type checking, documentation, and IDE support. They enhance code readability, maintenance, and are crucial in API development, data science, and library creation.
