Executing Multiline Statements in the One-Line Command-Line with Prerequisites

When executing Python one-line loops using the -c option, including module imports can lead to syntax errors. However, there are several approaches to overcome this limitation and execute multiline statements efficiently in a one-liner.

One solution is to use the echo command followed by piping the statements to Python:

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

Another method involves using Python's exec() function to execute the statements dynamically:

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

Alternatively, you can split the statements into multiple lines and pipe them separately to Python:

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

By utilizing these techniques, you can effectively execute complex multiline statements, including module imports, in a single-line command-line, fulfilling the requirement of incorporating such statements in a Makefile.
