Hey Everone, In this video, I have tried to explain few basic concepts of python...
Though one video is not enough to learn everything about python, this video is enough to get you started and give you some exposure to the basic idea of python programming language.
This video will give a quick summary of Python to someone who is just a beginner in Python. This video is a journey in learning Python from installation of Python to use of Oops concept in Python. Below we will give a short snippet of the topics covered here and will also attaching the duration of each topic to help you get to the exact point you are looking for.
[4:45] Modules: They are files which has some functions used in python programming. Modules are used to save run-time, get the task done quick and keep the program look clean and professional.
[5:34] Print Function in Python: This is the starting point! We will see here how with the use of print function we can play around and print the results in our desired format!
[6:07] Comments: We will see the different data types in Python and how each should be used. Data Types in Python are: Numbers, Strings, Lists, Tuples and Dictionaries. Within numbers we have integers, floats, complex and long. Along with data types, we have also shown the use of various operators such as: addition, subtraction, multiplication, division, power and modulus. Moreover since python is a very simple language, it does not require the data types of the variables to be declared explicitly before assigning values to them. The type () function will tell which category of the data type a variable belongs to. In case of List, we will see how to define a list, how to add, remove or change elements in a list. This shows that Lists are mutable. Next we will move to tuples, how to define them and how tuples are immutable as compared other data types. In order to change elements in a tuple, we will convert them into a list and then perform any operation which the list satisfies. Next we move to dictionaries which run on the concept of key-value pair. Dictionaries too are mutable.
After these topics, I have explained the following topics. Timestamps for each topic is mentioned below!
[8:06] Strings
[8:50] Variables in Python
[9:09] Data Types in Python
[9:35] Operators in Python
[13:10] More about strings
[15:45] Lists in Python and Add items in a List
[18:40] List Indexing and Add Items In List
[22:15] Tuples in Python
[23:57] Dictionaries in Python
We will further move to conditional statements with the use of if-else statements. Moreover, to iterate such multiple conditions several times, we will use the concept of loops. We will also look at how to define functions which will make our life much easier. Below three videos are representation of the same.
[26:24] If-Else condition
[31:15] Loops in Python
[39:30] Functions in Python
Next we will look at different ways of file handling and the concept of OOPs in the last videos.
[45:00] File Handling in Python
[49:30] OOPs (Object Oriented Programming subject)
