this is done by returning a tuple. A tuple is a collection of values separated by commas and enclosed in parentheses. For example, a function that calculates the average and standard deviation of a list of numb
在7.1.1 的例子中,函数 example() 的定义中,变量 username 是一个形参——函数完成其工作所需的一项信息,在代码 example(‘TRHX’) 中,值’TRHX’是一个实参,实参是调用函数时传递给函数的信息,调用函数时,将要让函数使用的信息放在括号内。在 example(‘TRHX’) 中,将实参 ‘TRHX’ 传递给了函数 example...
tuple: 返回一个包含整数和字符串的元组。 """returnparam1, param2 调用这个函数后,可以将返回的元组赋值给一个变量,并分别访问其中的元素: result = example_function(10,"hello")print(result)# 输出:(10, 'hello')x, y = example_function(10,"hello")print(x)# 输出:10print(y)# 输出:hello 函数...
In the above example, we have created a function namedfind_square(). The function accepts a number and returns the square of the number. Working of functions in Python Note:Thereturnstatement also denotes that the function has ended. Any code afterreturnis not executed. The pass Statement The...
In general, a function takes arguments (if any), performs some operations, and returns a value (or object). The value that a function returns to the caller is generally known as the function’s return value. All Python functions have a return value, either explicit or implicit. You’ll ...
return result @TimerDecorator def example_function(): time.sleep(1) print("Function executed") example_function() 在这个例子中,TimerDecorator类通过__call__方法实现了装饰器逻辑 ,测量并打印了被装饰函数example_function的执行时间。 2.3 深入理解装饰器应用场景 ...
Note: After getting multiple values,numbersbehave as anarrayso we are able to use thefor loopto access each value. Write a function to return a full name with a space in between. For example, if theisJohnand theis, the return value should beJohn Doe....
return sum example_function(1000000) 输出示例: example_function ran in: 0.12345 secs2.2 使用functools.wraps保持元信息 直接应用上述装饰器会丢失被装饰函数的一些重要属性,比如函数名、文档字符串等。为了解决这个问题,可以使用functools.wraps来保留这些元数据: ...
test指向了新的函数,原本test()函数的返回值被functionName()接受了。因此,如果想要输出“Python”需要使用return语句将调用后的结果返回。对装饰器进行修改,修改后的代码如下: 再次调用test()函数,发现成功得到了返回值。 2.5 带有参数的装饰器 前面的装饰器都是不带参数的,这些装饰器最终返回的都是函数名。如果我...
