Help with ValueError using ranint from random.
#1
Hi, I'm making a program that generates a given quantity of numbers randomly and prints them, but I don't understand why I get this error:

The code:
from random import randint


# n: normal, generates odd and even numbers.

def n_repeated(q_of_nums, minimum_number, maximum_number):
	"""Generates odd and even numbers, they can be repeated."""
	print("The generated numbers are:")
	for i in list(range(q_of_nums)):
		x = randint(minimum_number, maximum_number)
		return

def n_nonrepeated(q_of_nums, minimum_number, maximum_number):
	"""Generates odd and even numbers, they can't be repeated."""
	printed_numbers = []
	print("The generated numbers are:")
	while printed_numbers < q_of_nums:
		for i in list(range(q_of_nums)):
			x = randint(minimum_number, maximum_number)
			if x in printed_numbers:
				continue
			else:
				print(x, end=' ')
				printed_numbers.append(x)


n_repeated(6, 40, 1)




The error:
Error:
The generated numbers are: Traceback (most recent call last): File "test.py", line 27, in <module> n_repeated(6, 40, 1) File "test.py", line 10, in n_repeated x = randint(minimum_number, maximum_number) File "C:\Users\Franc\AppData\Local\Programs\Python\Python37-32\lib\random.py", line 222, in randint return self.randrange(a, b+1) File "C:\Users\Franc\AppData\Local\Programs\Python\Python37-32\lib\random.py", line 200, in randrange raise ValueError("empty range for randrange() (%d,%d, %d)" % (istart, istop, width)) ValueError: empty range for randrange() (40,2, -38)
Thanks in advance for your help.

print values of minimum_number and maximum_number
just before executing line 10

You're trying to get randint(40, 1). But 40 > 1, so there are no possible numbers randint could return. The first number needs to be less than the second number.
