What Does if __name__ == "__main__" Mean in Python? Theif __name__ == "__main__"idiom is a Python construct that helps control code execution in scripts. It’s a conditional statement that allows you to define code that runs only when the file is executed as a script, not ...

One easy way to speed this up is to use astatic const unsigned chararray as an ASCII lookup table, which maps a residue directly to its complement. This would replace the nest ofifstatements and probably give a nice little boost (and it appears it does, ma...
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...
The with statement in Python wraps the execution of a code block using the methods defined by a context manager. It's commonly used to replace a try-finally block with more concise code.
When you decode this bytes literal into a string, Python replaces such combinations of bytes with an appropriate Unicode character. On the other hand, placing these same escape sequences in a string literal makes Python interpret them individually as separate ASCII characters. Fortunately, you can...
In this case, the object is my_file, instantiated with the open()function. This replaces several lines of boilerplate to open the file, read individual lines from it, then close it up. The [x … for x in my_file] construction is another Python idiosyncrasy, the list comprehension. It...
element is inserted at the correct position to maintain the sorting order, subsequent operations that rely on the sorting order may not function correctly. Some data structures, like certain types of binary trees, automatically maintain their sorting order when elements are inserted, but others do ...
