Creating and
running Python code can be done in several environments, including text
editors, integrated development environments (IDEs), or directly in a terminal
or command prompt. Here's a step-by-step guide on how to create and run Python
code:
### 1.
**Using a Text Editor or IDE**
#### **Step
1: Install Python**
Ensure
Python is installed on your computer. You can download it from the official
Python website: [python.org](https://www.python.org/downloads/).
You can
verify the installation by running the following command in your terminal or
command prompt:
```bash
python
--version
```
or
```bash
python3
--version
```
This should
display the installed Python version.
#### **Step
2: Write Python Code**
You can use
a simple text editor like Notepad (Windows), TextEdit (macOS), or more advanced
editors like Visual Studio Code, PyCharm, or Sublime Text.
1. **Open
your text editor or IDE.**
2. **Write
your Python code.** For example, create a simple "Hello, World!"
program:
```python
# hello.py
print("Hello, World!")
```
3. **Save
the file** with a `.py` extension, such as `hello.py`.
#### **Step
3: Run Python Code**
- **Using
the Terminal/Command Prompt:**
1. Open your terminal (macOS/Linux) or
command prompt (Windows).
2. Navigate to the directory where your
Python file is saved using the `cd` command:
```bash
cd path/to/your/file
```
3. Run the Python script using one of the
following commands:
```bash
python hello.py
```
or
```bash
python3 hello.py
```
- **Using
the IDE:**
If you're using an IDE like Visual Studio
Code or PyCharm, you can usually run the code directly by clicking the
"Run" button or pressing a shortcut like `F5`.
### 2.
**Using an Interactive Python Shell**
Python also
provides an interactive shell (REPL) where you can write and run Python code line
by line.
#### **Step
1: Open the Python Shell**
- Open your
terminal or command prompt.
- Type
`python` or `python3` and press `Enter`.
You should
see something like this:
```bash
Python 3.x.x
(default, ...)
[GCC ...] on
linux
Type
"help", "copyright", "credits" or
"license" for more information.
>>>
```
#### **Step
2: Write and Run Code**
You can now
write Python code directly in the shell:
```python
>>>
print("Hello, World!")
Hello,
World!
```
#### **Step
3: Exit the Shell**
To exit the
shell, type `exit()` or press `Ctrl+D` (Linux/macOS) or `Ctrl+Z` and then
`Enter` (Windows).
### 3.
**Using Jupyter Notebook**
Jupyter
Notebook is an interactive web-based environment that allows you to create and
run Python code in cells, making it ideal for data analysis, visualization, and
exploratory programming.
#### **Step
1: Install Jupyter Notebook**
If you
haven't installed Jupyter Notebook, you can do so using pip:
```bash
pip install
notebook
```
#### **Step
2: Launch Jupyter Notebook**
In your
terminal or command prompt, type:
```bash
jupyter
notebook
```
This will
open Jupyter Notebook in your web browser.
#### **Step
3: Create a New Notebook**
1. In the
Jupyter interface, click "New" and select "Python 3" to
create a new notebook.
2. Write
your Python code in the cells.
3. Run the
cells using the "Run" button or by pressing `Shift + Enter`.
### Summary
- **Text
Editor/IDE:** Write code in `.py` files and run them using a terminal/command
prompt or the IDE itself.
-
**Interactive Python Shell:** Run Python code interactively in a terminal or
command prompt.
- **Jupyter
Notebook:** Use for more interactive, cell-based Python coding.
