Hi Reader, I hope you are having a good day and will have a great life from now on.

Python
1)Recursive Functions:
Every recursive function has a base case that stops it from going into the fourth dimension(that's what I like to think 😅).
Example 1:
Every recursive function has a base case that stops it from going into the fourth dimension(that's what I like to think 😅).
Example 1:
Recursive functions can be implemented with more than one function. Here's an example for checking even and odd numbers
Example 2:

2)Sets
Sets are the same as in maths, unordered and unique.
-It can't have unhashable data types i.e. mutable data types like list and dictionary.
Syntax:
set1={1,2,3,4}
-Doesn't allow duplicate elements

-It can't have unhashable data types i.e. mutable data types like list and dictionary.
Syntax:
set1={1,2,3,4}
-Doesn't allow duplicate elements
Functions:
set1.add(7) # adds 7
set1.remove(7) # removes 7
set1.pop() #removes a random element
len(set1) # gives number of elements in se
set1.add(7) # adds 7
set1.remove(7) # removes 7
set1.pop() #removes a random element
len(set1) # gives number of elements in se
Set operations as in maths.
Union "|":
a|b # means a union b
Intersection "&":
a & b #means a intersection b
Difference "-":
a - b # means a difference b
Symmetric Difference "^":
a ^ b # opposite of a & b.
Union "|":
a|b # means a union b
Intersection "&":
a & b #means a intersection b
Difference "-":
a - b # means a difference b
Symmetric Difference "^":
a ^ b # opposite of a & b.
3) Itertools
type-1: Infinite iterators.
First, import them in your code using
from itertools import count, cycle, repeat
i)count
Counts up infinitely from the starting value.
ii)cycle:
infinitely iterates through an iterable

iii)repeat
repeats an object infinitely or for a specific number of times.
An example of itertools is in the attached code snippet.
