Slicing in Python gets a sub-string from a string. The slicing range is set as parameters i.e. start, stop and step. Syntax Let us see the syntax # slicing from index start to index stop-1 arr[start:stop] # slicing from index start to the end arr[start:] # slicing from the ...
If it's not provided, it defaults to 1, which means taking every element in the specified range.Now, let's reverse a string using slicing.text = "Hello Python" print(text[::-1]) # Output : nohtyP olleH Python CopyLet's understand how slicing is working here. If you can see here...
‘stand’ is a substring of ‘understand’. In python, the slicing operation is used for picking the required substring from the main string, which is declared in the program. The syntax for substring goes like ‘string_var[start_index : end...
A very simple concept is used in slicing. When a string is indexed using a pair of offsets separated by a colon (:), Python returns a new string object that contains the section identified by the offset pair. In the offset pair, the left offset, lower bound, is inclusive, and the ri...
Slicing Strings Strings have indices, so we can refer to every position of a string with its corresponding index. Keep in mind that python, as many other languages, starts to count from 0!! print string[1] #get one char of the word print string[1:2] #get one char of the word (sam...
What is slicing in Python? Slicing in Python isa feature that enables accessing parts of sequences like strings, tuples, and lists. You can also use them to modify or delete the items of mutable sequences such as lists. Slices can also be applied on third-party objects like NumPy arrays...

Every object in Python has a class.Even classes have a class. A class's class is its metaclass and that's what type is.That's interesting. But what's the purpose of a class having a class?Dynamically creating classes with typeOne interesting feature of metaclasses, like type, is that ...
