Python Programming Guide — Learn Python In 24 Hours Or Less is a book for beginners to dive deep right into the language with examples. No prior knowledge of Python required.
Python is a very popular programming language and will continue to be so, however, programming can be overwhelming. This book brings you a concise, straight to the point, easy to follow code examples with screenshots so you can begin coding in 24 hours or less. Invest in yourself, practice programming in Python and you will be a Python programmer in no time.
To be able to use python, you need to ensure that your computer has all the requirements needs to run python. This chapter offers you all the instructions you need to follow to get started. There are different settings for python depending with the computer you want to use.
If you are using Mac OS X computers: You will not need to install Python program since you already have a Python 2. Neither will you need a any other version such as Python 3.
You many need other programs such as PowerShell if you are going to use windows, Terminal when using OS X and bash if you prefer using Linux. But if this is your first time using this program, then you will need to learn how they can be used first.
Just like I have expressed in the previous example, this codes can be read like an English story. Other words such as otherwise can be used instead of the word else, however, we use shorter words in Python to reduce the bulk of wording in programming.
Note also, that the code has two indented blocks of code. The after the if and after the else. The first block is the if statement. The indentation is executed only of the if is true otherwise, nothing happens. Next, when it is false, the else is executed as well. Hence, when using the if.. else statement, only one of the headings can be executed at any one, when if is true, else indented block is not executed, but when if is false, then the else indented block is executed.
When one would like to create more than two distinct cases and the conditions have only two possible conditions which can either be true or false. The only direct choice may be between the other two options. For instance, when one has about 20 questions, you can be able to make more cases by use of more questions. When there are more than two choices, a single test can be used to reduce the possibilities and other tests added will be able to lower the possible further. Statements will be required to be placed in a indented statement block and another added choice will be an extra if statement to the block.
The data variables come in the five ways: They can be in form of numbers, lists, tuples, strings and finally dictionaries. Each of them is very unique and working with python at every single process requires a basic understanding of their functions and classes.
In python, to better understand how this can be applied. You can seek help from the python by typing help (‘object’) or help (“object”) followed by enter. This will provide you with a solution on how any of the variables can be applied.
