$ pysed -p example.txt

Python is a widely used general-purpose, high-level programming language.
Its design philosophy emphasizes code readability, and its syntax allows
programmers to express concepts in fewer lines of code than would be possible
in languages such as C. The language provides constructs intended to enable
clear programs on both a small and large scale.
