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 ...
Identify the frequently used columns in WHERE, JOIN, and ORDER BY clauses for indexing. Batch Processing: Use batch processing for multiple INSERT, UPDATE, or DELETE operations. It reduces overhead by minimizing round-trips between the application and the database. Example: data = [(value1,)...
but a better fix is often to use a list comprehension (especially when the original code uses lambda), or rewriting the code so it doesn’t need a list at all. Particularly tricky is map() invoked for the side effects of the function; the correct transformation...
As in previous versions of Python, it’s guaranteed that float(repr(x)) recovers x. Float-to-string and string-to-float conversions are correctly rounded. The round() function is also now correctly rounded. The PyCapsule type, used to provide a C API for extension modules. The PyLong_As...
Python is a general-purpose programming language that can be used in different methodologies. It can be used to develop any modes of applications which include any complex functions. In our day to day life, we move through the search engine giant, Google, which is developed using Python. Also...
Function as a service (FaaS) is serverless computing for executing application functions. Find out how it works, what it's used for and its pros and cons.
if something is true then execute this piece of code otherwise do something else - this kind of “if-else” construction would usually require the use of parentheses along with other symbols like “>” and “<” operators. another common application involves function calls in some programming ...
