When it comes to working with lists in Python, there are a few different ways to add items to the end of the list. The two most common methods are to use the extend() method or the append() method.So, what is the difference between extend and append in Python?The difference between extend and append is that extend adds the items to the end of the list, while append adds the item to the list as a single element.If you want to add multiple items to the end of a list, then extend is the way to go. If you only want to add one item, then append will suffice.
Extend vs append python
Append is used when you want to add a single element at the end of the list.
Extend- when to use extend()?
Extend is used when you want to add multiple elements at the end of the list. It takes an iterable as an argument and appends each element of that iterable to the list.
Append vs extend python- performance
When it comes to performance, append is faster than extend. This is because extend requires allocating more memory in order to add the elements of the iterable to the list.
In summary, the main difference between append and extend in Python is that append adds an element to the list while extend adds multiple elements to the list. Append is faster than extend because it doesn’t require allocating more memory.
How do they both work
Append- Append adds an element to the list. It takes a single argument which is the element to be added. It doesn’t take an iterable as an argument like extend does.
Extend- Extend appends multiple elements to the list. It takes an iterable as an argument and adds each element of that iterable to the list.
When should you use extend and when should you use append in Python
Append is used when you want to add a single element at the end of the list. Extend is used when you want to add multiple elements at the end of the list. Append is faster than extend because it doesn’t require allocating more memory.It really depends on what you’re trying to do. If you want to add a single element to the list, then append is the way to go. If you want to add multiple elements, then extend is the best choice. Extend is also faster than append, so if performance is a concern, then extend is the better option.
Conclusion
In conclusion, extend and append are two ways of adding items to the end of a list in Python. The main difference between extend and append is that extend adds the items to the end of the list, while append adds the item to the list as a single element. If you want to add multiple items to the end of a list, then extend is the way to go. If you only want to add one item, then append will suffice. Append is also faster than extend, so if performance is a concern, then append is the better option.
