- The installation will begin. This might take a few minutes.

Once the installation is complete, check Run PyCharm Community Edition if you want to open it immediately.

Open desktop and click on PyCharm Logo.

This Dialogue Box will appear, when you click on desktop Shortcut .

After PyCharm opens, create a new project:
- Click New Project.
- Choose a location and name for the project.

If everything works as expected, your PyCharm setup is complete.

Right Click on your project name and select new.

In New select for New file Python file.

Name your Python file , here “Trial”.

Write a Trial program of printing a “Hello World” ,and to run that script right click on screen & select Run and Debug.

This Will be the output of the “Trial”. # printing “Hello World “

Python installation in Windows OS:

Open Google Chrome or any other web browser and search for Python.
Visit the official Python website at python.org.
Navigate to the Downloads section and select the latest stable release for Windows.Choose the appropriate installer based on your system architecture:
For 64-bit systems: “Windows installer (64-bit)”
For 32-bit systems: “Windows installer (32-bit)”
Locate the downloaded installer file (e.g., python-3.x.x-amd64.exe) and double-click to run it.

Check the box labeled “Add Python to PATH” to ensure you can run Python from the command line.Click on “Install Now” to proceed with the default installation.

In the “Optional Features” section, you can select additional components like:
- Documentation
- pip (Python package installer)
- tcl/tk and IDLE (Python’s Integrated Development and Learning Environment)
- Python test suite
- py launcher

Click “Next” and in the “Advanced Options” section, you can:
- Choose the installation location
- Add Python to environment variables
- Install for all users

After selecting the desired options, click “Install” to begin the installation.

Verify the Installation:
- Open the Command Prompt:
- Press Win + R, type cmd, and press Enter.
pip --version run in command prompt and python --version.

Python Installation for MacOS:

Check System Requirements: Ensure your macOS version is 10.9 or later.
Go To google chrome and search python

Visit Python’s Official Website: Open https://www.python.org and navigate to the “Downloads” section. The website will auto-detect the appropriate version for macOS.

Wait until the installation take place & navigate in download bar.

Open the .pkg file.

Click to continue.

Again click on continue.

Now click on Agree.

Now close all the tabs and open IDLE python.

Open IDLE shell and try a hello world Program.

Simple “Hello World” program.You can also check version in Terminal by giving the following command to check the version of python.
python3 –version

Python List vs Tuple

BeginnerLesson 21 of 477 min read6 runnable examples

Lists and tuples both store ordered sequences, and both support indexing, slicing and loops. The difference that matters is that a list can change and a tuple cannot. That one difference decides which to use.

In this lesson

The key differences at a glance
Memory and speed compared
Why tuples can be dict keys
A simple rule for choosing

Differences at a glance

	List	Tuple
Syntax	`[1, 2, 3]`	`(1, 2, 3)`
Mutable	Yes: add, remove, change items	No
Methods	Many: `append`, `remove`, `sort`…	Two: `count`, `index`
Can be a dict key / set item	No	Yes, if its items are hashable
Memory	More	Less
Typical use	A collection that grows or changes	A fixed record of values

Mutability in practice

Python

cart = ["pen", "book"]cart.append("bag")cart[0] = "pencil"print(cart) location = (18.52, 73.86)print(hasattr(location, "append"))

Output

['pencil', 'book', 'bag']
False

Memory and speed

A tuple uses less memory than a list with the same items, because a list keeps spare room so it can grow.

Python

import sys items_list = [1, 2, 3, 4, 5]items_tuple = (1, 2, 3, 4, 5)print(sys.getsizeof(items_list), sys.getsizeof(items_tuple))

Output

104 88

Creating a tuple of constants is also faster, because Python can build it once when the code is compiled:

Python

import timeit print(timeit.timeit("[1, 2, 3, 4, 5]", number=1_000_000) > timeit.timeit("(1, 2, 3, 4, 5)", number=1_000_000))

Output

True

Note

The exact sizes and timings depend on your Python version and computer. The direction does not: tuples are smaller and faster to create.

Hashability: tuples as keys

Only immutable objects can be dictionary keys or set members.

Python

visited = {(0, 0), (0, 1), (1, 1)}print((0, 1) in visited) grid = {(2, 3): "wall", (4, 1): "door"}print(grid[(4, 1)])

Output

True
door

Python

visited = {[0, 0], [0, 1]}

Output

Traceback (most recent call last):
  File "main.py", line 1, in <module>
    visited = {[0, 0], [0, 1]}
              ^^^^^^^^^^^^^^^^
TypeError: cannot use 'list' as a set element (unhashable type: 'list')

Converting between them

Python

t = (3, 1, 2)lst = list(t)lst.sort()t = tuple(lst)print(t)

Output

(1, 2, 3)

Which should you use?

Use a list when the collection will change: items are added, removed or sorted, such as a shopping cart or a queue of test cases.
Use a tuple when the values belong together and should not change, such as (latitude, longitude), an RGB colour, a function returning several values, or a dictionary key.

List vs tuple FAQ

Is a tuple faster than a list in Python?

Creating and iterating over a tuple is slightly faster and it uses less memory. The difference rarely matters; choose based on whether the data should change.

Why use a tuple instead of a list?

To signal that the data is fixed, to protect it from accidental changes, to use it as a dictionary key or set member, and to save a little memory.

Can a tuple contain a list?

Yes. The tuple cannot be changed, but the list inside it can. Such a tuple is not hashable, so it cannot be a dict key.
