There are other Python projects for creating PDFs, and several non-Python tools available for manipulating PDFs. If none of the Python solutions described here fit your situation, see the section [Other Tools][]
The behavior in first and second snippets is due to a CPython optimization (called string interning) that tries to use existing immutable objects in some cases rather than creating a new object every time. After being "interned," many variables may reference the same string object in memory (...

Programming solves problems by creating solutions—writing programs—in a programming language. The fundamentals of problem-solving and program- ming are the same regardless of which programming language you use. You can learn to program using any high-level programming language such as Python, Java,...
