1. >>> import random as rnd
   
2. >>> help(rnd.uniform)
   
3. Help on method uniform in module random:
   
4. 
   
5. uniform(a, b) method of random.Random instance
   
6.     Get a random number in the range [a, b) or [a, b] depending on rounding.
   
7. 
   
8. >>> help(rnd.expovariate)
   
9. Help on method expovariate in module random:
   
10. 
    
11. expovariate(lambd) method of random.Random instance
    
12.     Exponential distribution.
    
13.    
    
14.     lambd is 1.0 divided by the desired mean.  It should be
    
15.     nonzero.  (The parameter would be called "lambda", but that is
    
16.     a reserved word in Python.)  Returned values range from 0 to
    
17.     positive infinity if lambd is positive, and from negative
    
18.     infinity to 0 if lambd is negative.
    
19. 
    
20. >>>

1. import random
   
2. import math
   
3. print(random.uniform(1,5))
   
4. print(random.expovariate(1))#lambda is parameter

有没有服从幂率分布的随机数写法，貌似没找到
