How to Execute Multi-Line Python Commands in a Single Makefile Command?

Multi-Line Command Execution in a One-Line Makefile Command

When executing Python commands from the command line with the -c option, a syntax error occurs when importing a module before a multi-line loop. To resolve this issue, there are several approaches to consider:

Echoing to the Python Interpreter:

echo -e "import sys\nfor r in range(10): print 'rob'" | python

Using Python's exec Function:

python -c "exec(\"\"\"import sys\nfor r in range(10): print 'rob'\"\"\")"

Chaining Echo Commands:

(echo "import sys" ; echo "for r in range(10): print 'rob'" ) | python

These solutions allow the execution of multi-line commands within a single line, enabling the integration of Python code into Makefiles.
