What is Script in Python?

A script in Python can be explained as a file that consists of Python code or program. It ends with extension as .py An interpreter can execute a script in a two distinct ways as listed are:

  • A script can be executed as a module or as script itself.
  • A code that is written in the interactive Python command prompt session manner.

How to run Python code and scripts interactively?

Here are steps to do this:

Step 1: The programmer must open a command line in an interactive mode.

Step 2: In a next step invoke the python interpreter in a command line by typing the following command:

  • Command:
  • python

Step 3: The programmer can sequentially write a Python code and execute them in the same order.

The following program can be typed in a command line as shown:

Example:

  • Python Code
  • python
  • print (‘hello world Guru99’)
  • Output:
  • hello world Guru99
  • Let us take another Python code that could be written in a command line interactively.
Python Script

Example:

  • Python
  • a=25
  • b=50
  • if a > b:
  • … print (“a is more than b”)
  • … else:
  • … print (“b is more than a”)
  • b is more than a
  • >>>
  • Output:
  • b is more than a

Explanation:

The above code compares the two arguments and finds which argument is greater. Ensure the statements are properly indented to avoid indentation errors. To exit the windows command line press Ctrl+Z and follow with Enter.

How to run Python script files interactively from a Windows GUI?

Step 1: Open a command line and type the Python command followed by a script file name.

Step 2: Ensure that a script file is already created.

Step 3: The script file should end with either .py As a next step, open a Windows command prompt.

Python Command line Code:

  • Python example.py
  • Output:
  • Hello world!

How to run Python scripts from IDE:

An integrated development environment is also referred to as an IDE in short form. It offers a virtual setup of a file and folder hierarchy. It allows the programmer to build a Python projects quickly. IDE offers the organization of files into various folders.These various folders belong to one common directory.Spyder and PyCharm are the two Python IDEs that enable the programmer to run a Python programs.Let us take an example of executing the Python script in PyCharm IDE:

How to run Python scripts

Step 1: As a first step create new project in a PyCharm.

Step 2: Name project as a Guru99Example and then click create.

Step 3: Select a Root folder that would be labeled as Guru99Example and do a right click.

Step 4: Go to new option and create new Python file.

Step 5: Give a name of Python file.

Step 6: In blank Python file created in a PyCharm IDE write a following piece of code as shown below:

  • Python Code:
  • print (‘hello world Guru99’)

Step 7: To run above code right-click on an editor and select option Run File in Python console.

How to run Python scripts using file manager?

Here are steps to run a Python script using file manager:

Step 1: Open the Notepad and add some Python code.

Step 2: Type print (‘Hello World Guru99’)

Step 3: Save a script file with an extension as either .py

Step 4: . Programs utilize files with the py extension.

Step 5: In the Windows operating system right-click a Python file and click open.

How to run Python scripts using a script file name and command line?

Here are steps to run a Python script using script file name and command line:

Step 1: Open the Notepad and add some Python code.

Step 2: Type print (‘Hello World Guru99’)

Step 3: Save a script file with extension as either .py

Step 4: In a windows operating system right-click a Python file and click copy as path It helps to validate a path of script file with a command line path. Open a command line and type a script file name as created above with a name followed by an extension A script file created above can be run as a python module. Type following command as shown below:

  • Code:
  • python -m example

What Do You Need to Run a Python Script?

Following are the requirements needed to execute the Python Script:

  • Make a Python script executable and install the interpreter beforehand on a computer.
  • And should have a code editor or an integrated development environment pre-installed in a computer’s operating system.
  • Add Python beforehand to execute a code through the command line to operating system environment variable.

Conclusion:

A Python script can be executed using several methods.Can execute using a command line or using IDE.The programmer can use a PyCharm and Spyder IDE to develop the sophisticated Python scripts.Ensure that a code adheres to indentation when using the if and else statements in a command line.
