The even_numbers function returns a space-separated string of all positive numbers that are divisible by 2, up to and including the maximum that's passed into the function. For example, even_numbers(6) returns “2 4 6”. Fill in the blank to make this work.

even_numbers.py

def even_numbers(maximum):
    return_string = ""
    for x in range(2, maximum + 1, 2):
        return_string += str(x) + " "
    return return_string.strip()

Try this :

def even_numbers(maximum):

return_string = " "

for x in range(2,maximum+1):
 if x%2==0:
  return_string += str(x) + " "
return return_string.strip()

print(even_numbers(6))  # Should be 2 4 6
print(even_numbers(10)) # Should be 2 4 6 8 10
print(even_numbers(1))  # No numbers displayed
print(even_numbers(3))  # Should be 2
print(even_numbers(0))  # No numbers displayed

This works:

def even_numbers(maximum):
return_string = ""
for x in range(1,maximum+1):
if x%2==0:
return_string += str(x) + " "
return return_string.strip()

Another option:

def even_numbers(maximum):
	return_string = ""
	for x in range(2, maximum+1, 2):
		return_string += str(x) + " "
	return return_string.strip()

print(even_numbers(6))  # Should be 2 4 6
print(even_numbers(10)) # Should be 2 4 6 8 10
print(even_numbers(1))  # No numbers displayed
print(even_numbers(3))  # Should be 2
print(even_numbers(0))  # No numbers displayed

def even_numbers(maximum):
return_string = ""
for x in range(2, maximum + 1, 2):
return_string += str(x) + " "
return return_string.strip()

print(even_numbers(6)) # Should be 2 4 6
print(even_numbers(10)) # Should be 2 4 6 8 10
print(even_numbers(1)) # No numbers displayed
print(even_numbers(3)) # Should be 2
print(even_numbers(0)) # No numbers displayed

def even_numbers(maximum):
return_string=""
for x in range(2, maximum+1):
if x%2==0:
return_string+=str(x) +" "
return return_string.strip()

print(even_numbers(6)) # Should be 2 4 6
print(even_numbers(10)) # Should be 2 4 6 8 10
print(even_numbers(1)) # No numbers displayed
print(even_numbers(3)) # Should be 2
print(even_numbers(0)) # No numbers displayed
