【每日一坑 1】 随机取数

jox

我试试，取出不重复的值

1. import random
   
2. 
   
3. def pick_M_from_N(n, m):
   
4. 
   
5.   rawArr = range(1, n + 1)
   
6.   resultArr = []
   
7. 
   
8.   for i in range(0, m):
   
9.     arrLength = len(rawArr)
   
10.     pickedIndex = random.randint(0, arrLength - 1)
    
11.     resultArr.append(rawArr[pickedIndex])
    
12.     del rawArr[pickedIndex]
    
13.    
    
14.   return(resultArr)
    
15.   
    
16. if __name__ == "__main__":
    
17.     print(pick_M_from_N(33, 6))
    
18.     print(pick_M_from_N(16, 1))
