…m ctypes (#144595) When _ctypes is imported, it may call dlopen on the libpython shared library, causing the dynamic linker to load a second mapping of the library into the process address space. The remote debugging code iterates memory regions from low addresses upward and returns the first mapping whose filename matches libpython. After _ctypes is imported, it finds the dlopen'd copy first, but that copy's PyRuntime section was never initialized, so reading debug offsets from it fails. Fix this by validating each candidate PyRuntime address before accepting it. The validation reads the first 8 bytes and checks for the "xdebugpy" cookie that is only present in an initialized PyRuntime. Uninitialized duplicate mappings will fail this check and be skipped, allowing the search to continue to the real, initialized PyRuntime.
Add an example showing how to use str.translate() with a dictionary mapping directly, demonstrating character replacement and deletion. Co-authored-by: Claude Opus 4.5 <noreply@anthropic.com>
