[FIXED] writing a scrpy spider , something get wrong

Issue

Here is my code , I don't know how to fix it:

  File "<frozen importlib._bootstrap_external>", line 674, in exec_module
  File "<frozen importlib._bootstrap_external>", line 781, in get_code
  File "<frozen importlib._bootstrap_external>", line 741, in source_to_code
  File "<frozen importlib._bootstrap>", line 219, in _call_with_frames_removed
  File "C:\Users\shang\404.py", line 122
    for 'post-header' in response.css('header.post-header'):
       ^
SyntaxError: can't assign to literal

Solution

Your code is trying to assign the result of a function call (response.css()) to a string literal ('post-header'), which makes no sense.

You need to assign to a variable instead:

for x in response.css('header.post-header'):
    # do something with x

Note that the variable name x is just an arbitrary label, so you could also use a more readable name like post_header:

for post_header in response.css('header.post-header'):
    # do something with post_header
