Python is a popular programming language known for its simplicity, versatility, and ease of use. However, there are several hidden features and tricks that most developers are not aware of. In this blog, we will explore 10 Python hacks that can help you write more efficient and cleaner code.

1) Swapping Values with One Line of Code:

Often, when working with variables, you may need to swap their values. In other programming languages, you would need to use a temporary variable to swap the values. However, in Python, you can achieve this with one line of code.

2) Enumerate to Iterate Over a List with an Index:

When iterating over a list, sometimes you may need to know the index of the current item. In other programming languages, you would need to create a separate variable to keep track of the index. However, in Python, you can use the enumerate() function to iterate over the list with an index.

3) The Walrus Operator to Assign and Check a Variable in One Line:

The Walrus Operator, also known as the assignment expression, is a new feature introduced in Python 3.8. It allows you to assign and check a variable in one line.

Output:

4) List Comprehension to Filter and Modify a List:

List comprehension is a powerful feature in Python that allows you to filter and modify a list in one line.

Output:

5) The Zip Function to Combine Two Lists:

The zip function is a built-in function in Python that allows you to combine two lists into one.

Output:

6) The Any and All Functions to Check a List:

The any() and all() functions are built-in functions in Python that allow you to check if any or all elements in a list satisfy a certain condition.

7) The Setdefault Method to Set a Default Value for a Dictionary Key:

The setdefault() method is a built-in method in Python dictionaries that allows you to set a default value for a dictionary key.

8) The Get Method to Access Dictionary Values

The get() method is a built-in method in Python dictionaries that allows you to access dictionary values without raising a KeyError if the key is not found.

9) The Built-in Module “Secrets” to Generate Secure Random Numbers:

The secrets module is a built-in module in Python that provides functions for generating cryptographically secure random numbers. These functions are more secure than the functions provided by the random module, and should be used when security is important.

10) The Filter Function to Filter a List Based on a Condition:

The filter() function is a built-in function in Python that allows you to filter a list based on a condition. It returns an iterator that contains the elements from the original list that satisfy the condition.

By incorporating these hacks into your Python code, you can save time and effort while writing code that is more readable, efficient, and secure.
