For those wondering, using biopython is slower for this (~50% slower than the naive implementation), presumably due to the overhead of converting the strings toSeqobjects. If one were already reading sequences in using biopython, though, I wouldn't be surprised...
In Python, \n is a type of escape character that will create a new line when used. There are a few other escape sequences, which are simple ways to change how certain characters work in print statements or strings. These include \t, which will tab in your text, and \", which will ...

Discover What is Fibonacci series in C, a technique that involves calling a function within itself to solve the problem. Even know how to implement using different methods.
The'r'prefix before a string literal in Python denotes a___string, where escape sequences are not processed. The'u'prefix was used in Python 2.x to indicate a___string, representing Unicode characters. In Python 3.x, strings are Unicode by default, so the'u'prefix is ___ wh...
What is the main purpose of a compiler? Many modern-day computer programs are written in high-level programming languages, like Java, C++ orPython. However, machines cannot understand these programs as written -- much less execute them. The programs must first be translated into a language that...
Here's a fun project attempting to explain what exactly is happening under the hood for some counter-intuitive snippets and lesser-known features in Python.While some of the examples you see below may not be WTFs in the truest sense, but they'll reveal some of the interesting parts of ...
Like str, the bytes type is immutable. There is a separate mutable type to hold buffered binary data, bytearray. Nearly all APIs that accept bytes also accept bytearray. The mutable API is based on collections.MutableSequence. All backslashes in raw string literals are interpreted literally. Th...
