To sort a Python list, use the built-in sort() method. For example: Output: Or to reverse sort a list of numbers, you can do: These two are some basic uses of the sort() method in Python. But you can do a lot more with it too, such as: To learn how these and much more, […]

Python continue statement is one of the loop statements that control the flow of the loop. More specifically, the continue statement skips the “rest of the loop” and jumps into the beginning of the next iteration. Unlike the break statement, the continue does not exit the loop. For example, to print the odd numbers, use

In Python, None is an object implemented by the NoneType class. In Python, None represents an absence of a value in a variable. In Python, None is what would be a null in other commonly used programming languages. Unlike the null in the other languages, Python’s None has nothing to do with values 0 or

In Python, a mutable object can be changed, but an immutable object cannot. For example, a tuple is an immutable data type. You cannot change its elements after creating it: In contrast, a list is a mutable collection. You can change its contents afterward: This is a comprehensive guide to understanding the concepts of mutable

In Python, copying a list can be unintuitive for beginners. This is because you cannot use the assignment operator to take an independent copy of a list. To create an independent copy of a list in Python, you need to use the copy module’s deepcopy() function like this: This comprehensive guide teaches you how to

A leap year is a year that is divisible by 4. The exception is the years that are divisible by 100 but not by 400. But how do you make a Python program to calculate this? This comprehensive guide teaches you how to check if a year is leap year in Python. You will also

To print the contents of a list in Python, all you need to do is call the print() function on it. Here is an example of printing a list of three fruits in a list: Output: But if you want to print each element of a list separately, you should use a for loop. For

Printing and returning are fundamentally different concepts in Python. Example Here is an example of a function that prints a value. If you call this function, you can see a greeting in the console: Output: Here is an example of a function that returns a value. When you call this function with a name input,

Python switch-case statements are here as of Python 3.10! These statements are actually called match-case statements. With a match-case statement, you can get rid of rather verbose if-elif-else chains like this: Instead, you can use a compact match-case expression to do the exact same: In some situations, the latter approach is better. It can make
