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...
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...

In Python, you can use an assignment statement to mutate an object. Assigning to an attribute, index, or key will mutate the object that contains that attribute, index, or key.
= 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 ...
自从Python 3.8版本以来,代码可以使用所谓的“海象”运算符(:=),在PEP 572中有详细说明,用于赋值表达式。 这似乎是一个非常重要的新功能,因为它允许在推导和lambda函数中进行这种形式的赋值。 关于赋值表达式的语法、语义和语法规范具体是什么? 为什么引入了这个新的(看起来相当激进)的概念,即使PEP 379(提出了类似的...
