Python | sympy.randprime() method

With the help of sympy.randprime() method, we can find a random prime number in the range [a, b), where a and b are parameters to the method.

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.

Example #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))

Output:

A random prime between 4 and 50 is 37

Example #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))

Output:

A random prime between 60 and 100 is 79
