The = (equal to) symbol is defined as assignment operator in Python. The value of Python expression on its right is assigned to a single variable on its left. The = symbol as in programming in general (and Python in particular) should not be confused with its usage in Mathematics, where...
eg: 特殊操作: 1.链式赋值 2.交叉赋值 3.解压赋值 3 1 2 [3, 1, 2] # _是合法的变量名,会接受值,但我们认为_代表该解压位不用接收,用_来接收表示
In C programming, assignment operators are used to assign values to variables. The simple assignment operator is =. C also supports shorthand assignment operators that combine an operation with assignment, making the code more concise. Key Topics: Simple Assignment Operator Shorthand Addition Assignment...

Like most new features in Python, assignment expressions were introduced through a Python Enhancement Proposal (PEP). PEP 572 describes the motivation for introducing the walrus operator, the details of the syntax, and examples where the := operator can be used to improve your code. This PEP wa...

= is the assignment operator, χ = γ copies the value of y into x. In this example, if γ is undefined, χ becomes undefined. The assignment operator can be used with all four built-in data types. ▪ [] is the array index operator. Strings can be indexed using the array index ...
Python's walrus operator := allows you to assign a value to a variable within an expression, combining assignment and use in a single step.
In this course, you'll learn about assignment expressions and the walrus operator. The biggest change in Python 3.8 was the inclusion of the := operator, which you can use to assign variables in the middle of expressions. You'll see several examples of h
