Python’s Hidden Gems: 5 Less Known Built-In Functions

As a Python developer, I’m always excited to discover new and innovative ways to write more efficient and effective code. One of the best ways to do this is by leveraging Python’s built-in functions, which can often simplify complex tasks and make our lives as developers much easier. In this article, I’ll be exploring five lesser-known built-in Python functions that you might not know about, but should definitely be using in your projects.

1. callable(x)

The callable(x) function returns True if x is callable, meaning it can be invoked like a function. This function is incredibly useful when working with variables that may or may not be functions. For example:

def hello():
    pass

hi = 1

print(callable(hello))  # True
print(callable(hi))   # False

As you can see, callable(x) is a simple yet powerful tool for determining whether a variable can be treated as a function.

2. More Hidden Gems

In addition to callable(x), there are several other built-in Python functions that are worth exploring. From enumerate() to zip(), Python has a wealth of built-in functions that can make our lives as developers much easier.
