Help with ValueError using ranint from random.

[FWendeburg]

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:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27

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.
