To get a substring from a string in Python, you can use the slicing operator string[start:end:step]. The slice operator returns the part of a string between the "start" and "end" indices. The "step" parameter specifies how many characters to advance after extracting the first character from the string. Besides the slice operator, you can get a substring from a string using the Regular Expressions (re). In this Python Substring Example, we use the slicing operator to get a substring from the provided string. Below you can see an example of getting a substring using Regular Expressions.

How do I append items to a Python list?
In Python, you can append an element to a list using the list.append() or insert an element into a list using the list. insert() or list.extend() methods. The list.append() method appends an element to the end of the list. The list.insert() method inserts an element at the specified index (position). Indexing starts from zero, and a negative index of -1 means that the element will be added to the index starting from the end of the list. If you want to concatenate multiple lists, use the "+" operator. You can add elements of different types to the list (numbers, strings, etc.). In this Python List Append Example, we use the list.append() method to add an item to the end of the list. Additional examples of adding items to the list are provided below with detailed descriptions. Click Execute to run the Python List Append Example online and see the result.
