Root Cause

The input() function hit an end-of-file condition (EOF) without reading any data. Common in piped input, redirected stdin, or closed file descriptors.

Workarounds

  1. 90% success Check sys.stdin.isatty() before calling input() 
    If not a TTY, read from sys.stdin directly or use command-line arguments
  2. 90% success Use argparse or click for non-interactive input 
    Accept data via CLI arguments instead of interactive prompts

Dead Ends

Common approaches that don't work:

  1. Retrying input() in a loop 80% fail

    If stdin is closed, it will keep raising EOFError indefinitely
