The name of the operator function corresponds to the name of the appropriate Dunder method. You can use this table as a reference for implementing your own operator functionality:Python operator Operator function Dunder method a + b operator.add(a, b) a.__add__(b) ...

In this case, you want a range, so you use the colons. Within a square bracket, the number before the first colon is the start index and includes this index. If you don't include a number it defaults to the beginning of the list. The number after the first colon is the end index...
using the slice operator we are trying to extract elements. We give the start value 0, and stop value 5 and step value 1. When we run the program, we will get elements from 1 to 5 as the end value is non-inclusive.
First, you can use theslicing operator, colon ‘:’ inside the square brackets ‘[]’; the second method is theslice()function. This approach is usually used in the field of data analysis and manipulation. Let’s see how to perform string slicing in Python. ...
The second approach to coding in Python is to use a code editor. Some people prefer an integrated development environment (IDE), but a code editor is often better for learning purposes. Why? Because when you’re learning something new, you want to peel off as many layers of complexity as...
Let’s use two negative index numbers to slice the stringss: print(ss[-4:-1]) Copy Output ark The substring “ark” is printed from the string “Sammy Shark!” because the character “a” occurs at the -4 index number position, and the character “k” occurs before the -1 index nu...

Example 1: Concatenating Lists with “+” Operator We can use the “+” operator in Python to concatenate the lists. Using the “+” operator, you can join two or more lists to form a new list. When you use the “+” operator with lists, a new list is created and the elements of...
TypeError: unhashable type: 'slice' in Python A TypeError is raised in Python when we try to perform some unsupported operation on a given data type. A TypeError can also be raised while slicing if we try to use this technique on unsupported data types like a dictionary, DataFrame, and mor...
