## 为什么我选择了Python | ||
|
||
目前,Python语言的发展势头在国内国外都是不可阻挡的,Python凭借其简单优雅的语法,强大的生态圈从众多语言中脱颖而出,如今已经是稳坐编程语言排行榜前三的位置。国内很多Python开发者都是从Java开发者跨界过来的,我自己也不例外。我简单的跟大家交代一下,我为什么选择了Python。 | ||
|
||
### Python vs. Java | ||
|
||
我们通过几个例子来比较一下,做同样的事情Java和Python的代码都是怎么写的。 | ||
|
||
例子1:在终端中输出“hello, world”。 | ||
|
||
Java代码: | ||
|
||
```Java | ||
class Test { | ||
|
||
public static void main(String[] args) { | ||
System.out.println("hello, world"); | ||
} | ||
} | ||
``` | ||
|
||
Python代码: | ||
|
||
```Python | ||
print('hello, world') | ||
``` | ||
|
||
例子2:从1到100求和。 | ||
|
||
Java代码: | ||
|
||
```Java | ||
class Test { | ||
|
||
public static void main(String[] args) { | ||
int total = 0; | ||
for (int i = 1; i <= 100; i += 1) { | ||
total += i; | ||
} | ||
System.out.println(total); | ||
} | ||
} | ||
``` | ||
|
||
Python代码: | ||
|
||
```Python | ||
print(sum(range(1, 101))) | ||
``` | ||
|
||
例子3:双色球随机选号。 | ||
|
||
Java代码: | ||
|
||
```Java | ||
import java.util.List; | ||
import java.util.ArrayList; | ||
import java.util.Collections; | ||
|
||
class Test { | ||
|
||
/** | ||
* 产生[min, max)范围的随机整数 | ||
*/ | ||
public static int randomInt(int min, int max) { | ||
return (int) (Math.random() * (max - min) + min); | ||
} | ||
|
||
public static void main(String[] args) { | ||
// 初始化备选红色球 | ||
List<Integer> redBalls = new ArrayList<>(); | ||
for (int i = 1; i <= 33; ++i) { | ||
redBalls.add(i); | ||
} | ||
List<Integer> selectedBalls = new ArrayList<>(); | ||
// 选出六个红色球 | ||
for (int i = 0; i < 6; ++i) { | ||
selectedBalls.add(redBalls.remove(randomInt(0, redBalls.size()))); | ||
} | ||
// 对红色球进行排序 | ||
Collections.sort(selectedBalls); | ||
// 添加一个蓝色球 | ||
selectedBalls.add(randomInt(1, 17)); | ||
// 输出选中的随机号码 | ||
for (int i = 0; i < selectedBalls.size(); ++i) { | ||
System.out.printf("%02d ", selectedBalls.get(i)); | ||
if (i == selectedBalls.size() - 2) { | ||
System.out.print("| "); | ||
} | ||
} | ||
System.out.println(); | ||
} | ||
} | ||
``` | ||
|
||
Python代码: | ||
|
||
```Python | ||
from random import randint, sample | ||
|
||
# 初始化备选红色球 | ||
red_balls = [x for x in range(1, 34)] | ||
# 选出六个红色球 | ||
selected_balls = sample(red_balls, 6) | ||
# 对红色球进行排序 | ||
selected_balls.sort() | ||
# 添加一个蓝色球 | ||
selected_balls.append(randint(1, 16)) | ||
# 输出选中的随机号码 | ||
for index, ball in enumerate(selected_balls): | ||
print('%02d' % ball, end=' ') | ||
if index == len(selected_balls) - 2: | ||
print('|', end=' ') | ||
print() | ||
``` | ||
|
||
相信,看完这些例子后,你一定感受到了我选择了Python是有道理的。 |
