Python is a powerful programming language that offers a wide range of features to make code more readable and concise. One such feature is the ability to chain function calls together in a single line.
Let us briefly write an example and then explain it:
def add(a, b):
return a + b
def subtract(a, b):
return a - b
a, b = 4, 5
print((subtract if a > b else add)(a, b)) # 9 
In today’s digital age, unique identification is becoming increasingly important. Whether it’s for security purposes, data management, or simply keeping track of things, having a way to generate unique values is essential. One of the most popular ways to do this is through the use of UUIDs, or Universally Unique Identifiers.

In Python, tuples and lists are two commonly used data structures for storing collections of items.
The main difference between them is that tuples are immutable, meaning their elements cannot be changed after they are created, while lists are mutable, meaning their elements can be modified.
This immutability of tuples makes them more memory efficient and faster than lists since they can be used as keys in a dictionary and in sets.

One way to improve the concision of your Python code is by using the ternary operator, a handy tool that allows you to condense an if-else statement into a single line of code.
Let us jump straight into it.
Imagine that you have the following comparison:
x = 5
y = 10
if x > y:
result = x
else:
result = yYou can then write it in a single line:
result = x if x > y else y
The Python Counter class from the collections module is a powerful tool that we can also use for counting the occurrences of elements in a list.
