Snippets of String Since the final character ‘o’ isn’t always included in a string, Python implements a workaround by using negative integers to represent the characters at the end of the string. There are negative index numbers that count backward from the beginning of the string: There’s a “o” in the final character of s[-1] (1st from the end)

Secondly, What does :: 1 mean in Python?
Reversing a string, list, or any iterable with an ordering is accomplished by using [::-1]. “Hello world!” and the numbers “1, 2, 3, 4,” for example, may be printed (hello[::-1])
Also, Can you do ++ in Python?
The “(++ and –)” operators are not supported in Python. Reassigning a variable has the effect of both increasing and decreasing its value in Python. Python, on the other hand, does not support the “++” and “–” symbols.
People also ask, What is __ init __ in Python?
The __init__ function in Python is the object-oriented counterpart of the C++ constructor. An object is produced every time a class object is initialized. Aside from initializing the object’s properties, the __init__ function has no further use for the class. It’s only used in the classroom, of course.
