代码如下:
import random print random.random()
获取一个小于1的浮点数
代码如下:
import random random.randint(1,10)
获取一个从1到10的整数
代码如下:
import random print random.uniform(0,2)
获取一个大于0小于2的浮点数
代码如下:
import random print random.randrange(1,10,4)
获取一个从1到10步长为4的随机数
代码如下:
import random a=[1,2,3,4,5] random.choice(a)
从列表a从随机取出一个元素
代码如下:
import random a=[1,2,3,4,5] random.shuffle(a)
打乱列表a里元素的顺序
代码如下:
import random a=[1,2,3,4,5] random.sample(a,3)
从列表a中以随机顺序取出3个元素(一个元素只能取出一次,所以取出的个数不能大于列表所含元素的个数)

The methods to debug the shebang problem include: 1. Check the shebang line to make sure it is the first line of the script and there are no prefixed spaces; 2. Verify whether the interpreter path is correct; 3. Call the interpreter directly to run the script to isolate the shebang problem; 4. Use strace or trusts to track the system calls; 5. Check the impact of environment variables on shebang.

Create multi-dimensional arrays with NumPy can be achieved through the following steps: 1) Use the numpy.array() function to create an array, such as np.array([[1,2,3],[4,5,6]]) to create a 2D array; 2) Use np.zeros(), np.ones(), np.random.random() and other functions to create an array filled with specific values; 3) Understand the shape and size properties of the array to ensure that the length of the sub-array is consistent and avoid errors; 4) Use the np.reshape() function to change the shape of the array; 5) Pay attention to memory usage to ensure that the code is clear and efficient.
