水仙花数是指一个三位数，其各位数字的3次方和等于该数本身，用Python编写按照从小到大的顺序输出所有的3位数水仙花数，请用英文逗号分隔开结果，最后一个水仙花数之后不出现英文逗号

A narcissistic number is a three-digit number where the sum of its digits raised to the power of 3 equals the original number itself. Here's a Python code snippet that will generate and output all such numbers in ascending order, without commas between them once the sequence is complete:

# Function to check if a number is a narcissistic number
def is_narcissistic(num):
    return num == sum(int(digit) ** 3 for digit in str(num))

# Generate and collect narcissistic numbers within the range
narcissists = []
for i in range(100, 1000):  # Only consider three-digit numbers
    if is_narcissistic(i):
        narcissists.append(i)

# Output the result without commas after the last number
result = ', '.join(map(str, narcissists))
if len(result) > 0:
    print(result[:-1])  # Remove the trailing comma
else:
    print("No narcissistic numbers found.")
