Day 1

<p>Today I learned some basics in python like data types in python and about typecasting in python. There are two types of typecasting in python </P> 1.Implicit typecasting: conversion data types by program itself for e.g:

  a=10
     b=2.0
     sum=a+b
     print(sum)
     #sum will be in float because of implicit typecasting
   

2. Explicit typecasting: conversion of data types by programmer is called explicit typecasting . for e.g : <break>

 a=10
    b=2
    sum=a+b
    print(float(sum))
    #sum is in integer and changed to float using explicit typecasting

Day 2

<p>Here is day2 codes I have learned about string slicing . String in python is similar to array . </p>

  
 name="Elephant"
 length=len(name) #this len function provides the length of name
 print(name[2:3]) #this print e
 print(name[1:5]) #this print leph
 #this above example is string slicing

Greeting program

<p>This program greet you according to your time . It import time from your computer using

import time

Then it convert time into string using

strftime()

After that greeting is done using elif codition as seen below :

Day3

Match case statement

Match case is similar to switch case in c and c++ but there is no necesary of using break If you donot know about c and c++ Match case is used to select case according to option here is a sample program:

Day4

List

It is a sequence data types in python that is a collection of sequence of elements. for e.g:

lst=[1,2,56,"hari","alex",false]

Yes as you can see list can contains different data types.

Tuples is also similar to list but it cannot be changed (i.e immutable) Clear explanation of list is shown below

List method

There are various method to perform with list that help in program some of them are:

list.sort()

It sort the list in ascending order

list.index()

It gives index of first occurence of the list item

here output will be 1 for colours list and 3 for num list .

list.count

It counts number the number of items of given value for e.g colors.count("green") This will count number of time green occured in list colors

All others important list method are as follows :

Day5

Today we are going to learn about the tuples in python . Tuples are similar to list but it is immutable(i.e it cannot be changed). It also hold collection of data items . Tuples items are separated with comma and enclosed with small brackets for e.g:

tuple=(1,4,6,7)
tuple=(1)
print(type(tuple))  #this is printed as class int it should contain one , to be tuple
tuple=(1,)           
print(type(tuple))  #this is printed as class tuple

Note : Tuples cannot be changed it is constant and use in cases where we want constant list .

Day6

Today I learned about the method on tuples . Tuples exactly is immutable so it does not have any method that changes data item but we can perform this by changing tuples into list changing data items and changing it to tuples . Although we can perform some operation like index,len,etc . Code for the method in tuples is shared below hope you get some insights .

Day7

f-string

f-string is a new string formatting mechanism that allow us to enter variable directly in between the string according to our format. for e.g:

val="geek"
print(f"{val} for {val} is a portal for {val}")

Docstrings

Python docstrings are the string literals that appears right after the definition of function,class,method or module. Its like comment but its not ignored by python interpreter and cannot be used anywhere it mostly used to describe function workflow

PEP 8

PEP 8 is a guidline in python programming that makes python readable,maintainable and consistent . It stands for Python Enhancement Proposals

Set

Set is an unordered collection of data items in a single variable enclosed by curly braces and element separated by comma . Set doesnot contain duplicate item

Day8

Recursion

Recursion is the special case in which function call itself directly or indirectly to meet desired result. such function is called recursive function

Day9

Methods on sets

1.union() and update()

union() helps to find the union of two sets and update helps to update the sets value.

s1={1,4,5,7,9}
s2={1,4,6,7,8,9}
print(s1.union(s2))
s1.update(s2)
print(s1)

2.intersection() and intersection_update()

intersection() finds common value of two sets wherease intersection_update() update the sets with intersection.

3.symmetric_difference() and symmetric_difference_update()

symmetric_difference() gets items that are not similar on two sets and symmetric_difference_update() the sets with different items of two sets

4. difference() and difference_update()

difference() gets items that are not similar from original sets and difference_update() update the sets with difference items from original sets.

Day10

Other sets methods

Some of other sets methods that we can use are:

Day11

Dictionaries in python

Dictionaries are ordered collection of data items. They store multiple items in a single variable.Dictionaries items are key-value pairs that are
