Python函数返回值实例分析

python function return value

本文实例讲述了Python的函数返回值用法。分享给大家供大家参考。具体分析如下:

最近学一些Python的基本用法,看到定义函数,发现似乎只能返回一个返回值,想想matlab里返回多个返回值多方便啊,网上查了查,看到有返回多个值的方法。
 
python 函数返回值有两种形式:

1 返回一个值。
2 返回多个值。
 
现看看返回一个值的吧。

def firstvalue(a,b):
 c = a + b
 return c
print firstvalue(1,2) #结果:3

Copy after login

再看看返回多个值的: 那怎么可以返回多个值呢,其他的语言一般调用函数的话,只能返回一个值,可能我不太熟悉所有的语言,我知道的语言只能返回一个值,而python可以返回多个值,感觉非常方便,发代码看下:

def secondvalue(a,b):
 c = a + b
 return (a,b,c)
x,y,z = secondvalue(1,2)
print 'x:',x,'y:',y,'z:',z

Copy after login

希望本文所述对大家的Python程序设计有所帮助。

What is the function of C language sum? What is the function of C language sum? Apr 03, 2025 pm 02:21 PM

There is no built-in sum function in C language, so it needs to be written by yourself. Sum can be achieved by traversing the array and accumulating elements: Loop version: Sum is calculated using for loop and array length. Pointer version: Use pointers to point to array elements, and efficient summing is achieved through self-increment pointers. Dynamically allocate array version: Dynamically allocate arrays and manage memory yourself, ensuring that allocated memory is freed to prevent memory leaks.

Is distinctIdistinguish related? Is distinctIdistinguish related? Apr 03, 2025 pm 10:30 PM

Although distinct and distinct are related to distinction, they are used differently: distinct (adjective) describes the uniqueness of things themselves and is used to emphasize differences between things; distinct (verb) represents the distinction behavior or ability, and is used to describe the discrimination process. In programming, distinct is often used to represent the uniqueness of elements in a collection, such as deduplication operations; distinct is reflected in the design of algorithms or functions, such as distinguishing odd and even numbers. When optimizing, the distinct operation should select the appropriate algorithm and data structure, while the distinct operation should optimize the distinction between logical efficiency and pay attention to writing clear and readable code.

How to understand !x in C? How to understand !x in C? Apr 03, 2025 pm 02:33 PM

!x Understanding !x is a logical non-operator in C language. It booleans the value of x, that is, true changes to false, false changes to true.
