In this tutorial, you'll explore Python's __pycache__ folder. You'll learn about when and why the interpreter creates these folders, and you'll customize their default behavior. Finally, you'll take a look under the hood of the cached .pyc files.
What is the fastest way to get the reverse complement of a sequence in python? I am posting my skeleton program to test different implementations below with DNA string size 17 as an example. #!/usr/bin/env pythonimport randomimport timeitglobal complementcomplemen...
The function call random.randint() is evaluated eagerly, and its value is returned immediately. All standard functions are evaluated eagerly. You’ll learn about generator functions later, which behave differently. Lines 8 to 12: The final example has three lines of code: The literal to create...

Initially, you’ll be finding yourself typing the old print x a lot in interactive mode. Time to retrain your fingers to type print(x) instead! When using the 2to3 source-to-source conversion tool, all print statements are automatically converted to print() function calls, so this is most...
in the same line, the Python interpreter creates a new object, then references the second variable at the same time. If you do it on separate lines, it doesn't "know" that there's already "wtf!" as an object (because "wtf!" is not implicitly interned as per the facts mentioned abov...
