Python| sympy.randprime() 方法

借助sympy.randprime()方法，我们可以在[a, b)范围内找到一个随机素数，其中a和b是该方法的参数。

Syntax: randprime(a, b)

Parameter:
a – It denotes the start of the range. It is inclusive.
b – It denotes the end of the range. It is not inclusive.

Returns: Returns a random prime in the given range. If no prime is present in the range then it raises a ValueError.

示例 #1：

# import randprime() method from sympy
from sympy import randprime
  
a = 4
b = 50
  
# Use randprime() method 
a_randprime_b = randprime(a, b) 
      
print("A random prime between {} and {} is {}".format(a, b, a_randprime_b))

输出：

A random prime between 4 and 50 is 37

示例 #2：

# import randprime() method from sympy
from sympy import randprime
  
a = 60
b = 100
  
# Use randprime() method 
a_randprime_b = randprime(a, b) 
      
print("A random prime between {} and {} is {}".format(a, b, a_randprime_b))          

输出：

A random prime between 60 and 100 is 79
