Python Lesson 1

Lesson # 1

Hi All,

Today we start to learn python programming.

IDE: PyCharm Community Version - Download PyCharm

Definition

 Python is programming language and used for web development as well as machine learning, hardware programming.
So, why we learn Python. The answer is very clear.

1. Famous language in 2020
2. Easy to learn
3. Good market
4. More projects
5. Good earning

Who Learn Python

 Any person can learn Python if he has interest in solving the problem pro-grammatically.

Pre-Requirement

 This course is for those who have basic knowledge of programming and have interest in learning new technologies

Let’s start …….

My name is Salman and I am professional developer as well as blogger, teacher and learner.

History of Python

 ➔ Developed by Guido Van Rossum
➔ First release in 1991

Current Version

 ➔ Python 3.8.x Download Python Latest Version

Syntax

 We learn syntax in coming lessons but just need to remember
➔ Python didn’t used brackets such as { } to define the scope
➔ Python used indentation and white spaces instead

Installation:

 After downloading the Python latest version open the CMD or terminal (if using Linux) and do the below steps to check the python version

➔ python –version

I recommend installing PyCharm so this IDE handle everything for you.

Python Print

 To print the text use below syntax
➔ print (“Line 1”)
➔ Use + symbol to combine the string
➔ String1 = “Line 1”
➔ String2 = “Line 2”
➔ print (String1 + “ ” + String2)
➔ Output: Line1 Line2

Python Variables

 You can declare and initialize any variable without defining the datatype, datatype is defined by python interpreter when programmer initialize that variable.

Example
MyString = “Line 1” -> String
MyNumber = 10 -> Integer
MyPercentage = 10.50 -> Float
MyCollection = [“Line1”, “Line2”, “Line3”] -> Collection (List)

See you in lesson 2 :-)

Python Lesson 4

Lesson # 4 Hi All , In lesson 3 we start to learn the collection in python. We finish list. Today we learn more collection types. Tuples A tuple is collection which is ordered and unchangeable. It similar to List but only difference is once you create the tuple you are not able to change the orders, didn’t add more items, unchangeable. But yes, there is ways to add items or modify the values in tuple. If you need to add value in tuple, you need to create another tuple and join both. If you need to modify the tuple value, cast tuple into list, modify the value and again cast list to tuple. Example of tuple MyTuple = (“Banan”, “Apple”) In tuple ( ) brackets are used to declare and initialize the tuple. You can use count() and index() methods to search the values in tuple. Sets Sets is collection with unordered and unindexed data. It means there is no index associated with value. { } brackets are used to declare and initialize the sets...

Lesson 6 - Loops (While), Break, Continue

Hi, So today we learn loops. Many times we have some scenario where we need to repeat the steps. Here we come with solution called Loops. Python have "While" & "For" loop. While Loop While loop executed until the condition remains true. In while loop we initiate the variable that controls the counter for loop. Then apply the condition and inside the loop increment the counter by 1 or depends on your requirement. Example i = 1 while i <= 10:     print ("Do some coding")     i++ So first it check the conditions i <= 10 -> 1 <= 10 -> True -> Print -> Do some coding And so on until the condition is true. Above examples shows "Do some coding" 10 times. We can use below keywords inside loop to control the execution. 1. Break 2. Continue Break If our conditioned satisfied and we didn't need to execute the remaining we use break. It stops the execution and get the control out from loop. Continue We use "continue" ke...
