遍历函数对象而非返回值导致for循环无法获取迭代变量值的问题

Let's break down what's going wrong here and fix it step by step:

1. You're iterating over the function itself, not its return value
   In your loop for blog in my_blogs:, my_blogs refers to the function object itself—not the tuple of blog strings it returns when you call it. Iterating over a function won't give you the content you passed in.

2. You're calling the function after the loop runs
   Your my_blogs(blog_1, blog_2, blog_3) line comes after the loop finishes, so even if the loop was written correctly, it wouldn't have access to the returned values at that point.

Here's the corrected code: #

blog_1 = "Hello"
blog_2 = "I am a man"
blog_3 = "i am living"

def my_blogs(*args):
    return args

# Call the function to get the tuple of blogs, then iterate over that return value
for blog in my_blogs(blog_1, blog_2, blog_3):
    print(blog)

What changed: #

• We moved the function call my_blogs(blog_1, blog_2, blog_3) directly into the for loop's iterable. Now we're looping over the tuple that the function returns, which contains your three blog strings.
• Your function logic (using *args to capture variable arguments and returning them) is already correct—we just needed to make sure we're using its output properly.

If you want to reuse the returned collection later, you can also store it in a variable first:

all_blogs = my_blogs(blog_1, blog_2, blog_3)
for blog in all_blogs:
    print(blog)
