-While efficiency of a //program// is key to solving many contest problems, efficiency of the //programmer// is also critically important. Python3 is known for its expressive nature: problems that are solvable in Python3 are often solvable in far fewer lines than would be required in [[cpp_ref|C++]] or Java((At the time of the initial version of this guidebook, Java is not currently supported by the guidebook authors.)). Some of the easiest real-world contest problems can be solved in fewer than 5 or 10 lines of Python3 code. A firm grasp of Python3 may make the difference in solving easy and medium level problems, and doing so faster than other competitors.+While efficiency of a //program// is key to solving many contest problems, efficiency of the //programmer// is also critically important.

-The reverse is also true. Python3 may be the //wrong// choice for other problems. While Python3 boosts programmer efficiency, it inherently lacks runtime efficiency. Python3 cannot compete with well written [[cpp_ref|C/C++]]/Java code. Certain contest problems may not be solved within prescribed time bounds using Python3.+The reverse is also true.

-Fortunately, while a wrong choice of Python3 can be a (potentially major) setback in an actual competition, Python3 code follows many common pseudocode conventions and can be quickly converted to [[cpp_ref|C++]] or Java code. Such converted code is likely to perform significantly even before it is deliberately fine tuned.+Fortunately, while a wrong choice of Python3 can be a (potentially major) setback in an actual competition, Python3 code follows many common pseudocode conventions and can be quickly converted to [[cpp|C++]] or Java code.
