$ python function_global.py x is 50 Changed global x to 2 Value of x is 2 How It WorksThe global statement is used to declare that x is a global variable - hence, when we assign a value to x inside the function, that change is reflected when we use the value of x in the main...

The Walrus operator (:=) was introduced in Python 3.8, it can be useful in situations where you'd want to assign values to variables within an expression.def some_func(): # Assume some expensive computation here # time.sleep(1000) return 5 # So instead of, if some_func(): print(...
Line 1 shows a traditional assignment statement where the value False is assigned to walrus. Next, on line 5, you use an assignment expression to assign the value True to walrus. After both lines 1 and 5, you can refer to the assigned values by using the variable name walrus....
下面分析执行过程:在some_function()函数中中定义了一个新变量x = 22,它位于函索所定义的局部命名空间**中。之后,只要在函数内使用x,它指的就是在局部作用域内的那个x。若访问some_function()函数之外的x时,则指的是在x = 11中定义的那个x。
@app.function_name(name="HttpTrigger1") @app.route(route="req") def main(req): user = req.params.get("user") return f"Hello, {user}!" You can also explicitly declare the attribute types and return type in the function by using Python type annotations. Doing so helps you use the...
