I think every one of us is aware of the “Hello World” Program, that you script when you master a language like Python.

how to code in python

How to Create a Hello World Program in Python

Open Your Start Menu and select Python command Line.

You will see a line like >>>

With this, you can do everything in a communicative, and Interactive mode in Python Interpreter. Where >>> come in. Moreover, Python Shows you >>>, when you are going to type something in the command line.

At the prompt, type the below line, use only single Quote at the start and end, it’s beside the Enter key.

print(‘Hello World!’)

Then press the Enter Key.

Python Runs the code, that you type.

You can see the Output, as below, I think, if you write this program for the first time, then this is your first program and Output.

Output

Python 2.7.9  < default, Dec 2019, 05:43:54> [MSC V.1500 32 bit <intel>] on win 32

Type “help”, “copyright” or “license” for more information.

>>> print<‘ hello world ’>

Hello, world!

>>> _

If you dint see the Above Output, on your System, in the same way, do the following.

Check what you have typed from step 2.

The Single Quotes and Parentheses in the right positions.

Check, in the same way for every opening parenthesis, that there is a closing Parenthesis, that you left hanging.

Check for Every Opening Quote, there is a closing Quote.

Tips for how you code in Python

Note:

Every Programming language, have Inbuilt Own reference and Grammar Rules. Moreover, These Rules, are known as Language Syntax.

 

Finish Your Lab Work

Generally, we do fractions in our Python Lab. Use those Fractions, method and fraction Object, that select the Digit and Numerator.

For getting the One-half, type fractions.fraction(1,2). For four-fifths, type fractions.fraction(4,5):

>>> import fractions

>>> one_half = fractions.Fraction(1, 2)

>>> one_fifth = fractions.Fraction(1, 5)

With fractions, we do normal fraction calculations

> one_half+one_fifth

Fraction(7, 10)
>>> one_half-one_fifth

Fraction(3, 10)

>>> one_half*one_fifth

Fraction(1, 10)

>>> one_half/one_fifth

Fraction(5, 2)

What are Python Keywords?

Generally, every one of us knows, programming is an important skill. As a matter of fact, the below are the code words of Python, built-ins, set library functions, operators, that you use most when you do programming with Python.

Keyword

And – Logical Operator, for testing two things, whether they are true or not.

As – Assign a File object to a Variable, similarly if your code differs from a unit under a different name, that used with Import.

Break – It stops Executing a Loop.

How to script with Python Widgets

Python Widgets are Set Graphical User Interface Elements, similarly many buttons, and menus.

Option Menu Widget

Especially, Options Menu Widget will let you select, from a list of options. That is for using the Options menu, in the right way. In the same fashion, You may bind it to a separate call back. That which update, other Data, which is based on user selection.

import Tkinter

parent_widget = Tkinter.Tk()

control_variable = Tkinter.StringVar(parent_widget)

OPTION_TUPLE = ("Option 1", "Option 2", "Option 3")

optionmenu_widget = Tkinter.OptionMenu(parent_widget,

control_variable, *OPTION_TUPLE)

optionmenu_widget.pack()

Tkinter.mainloop()
Menu Widget:

Generally, With the menu Widget, you can Design a Menu bar. Designing menus is hard. If you concentrate on Drop-Down Menus. Consequently, Doing that, you can use a Separate menu, widget for every Drop down menu when you design it.

import Tkinter

parent_widget = Tkinter.Tk()

def menu_callback():

print("I'm in the menu callback!")

def submenu_callback():

print("I'm in the submenu callback!")

menu_widget = Tkinter.Menu(parent_widget)

submenu_widget = Tkinter.Menu(menu_widget, tearoff=False)

submenu_widget.add_command(label="Submenu Item1",

command=submenu_callback)

submenu_widget.add_command(label="Submenu Item2",

command=submenu_callback)

menu_widget.add_cascade(label="Item1", menu=submenu_widget)

menu_widget.add_command(label="Item2",

command=menu_callback)

menu_widget.add_command(label="Item3",

command=menu_callback)

parent_widget.config(menu=menu_widget)

Tkinter.mainloop()
How You can Name Functions In Python

Functions are known as best and most powerful tools, in programming toolbox. Because they accept, you to separate your program, into best and meaningful blocks.

Every Plug-in in Python, functions is from the Set library.

The Rules for naming a Function is like naming a Variable.

It is lengthier, but we should arrange them shorter.

They have Numbered.

Functions should be Lower case.

They have to start with underscore or Letters.

Functions are Not python keywords. In the same way, they will have the same name as the Existing function, but we have to avoid this as of Now.

I think this Blog will help you in, how you can Code in python and, up to my knowledge, coding is simple when we master the basics of any programming language. Just like alphabets in the English Language. For Every Language Fundamentals are Important.
