The first index sys.argv contains the name of the interpreter Python script. Consider our vulnerability scanner: what if we wanted to pass the name of a text file as a command line argument? The list sys.argv contains all the command line arguments. We may, for example, want to parse command line arguments at runtime. Interacting with the sys module can prove very helpful in creating Python scripts. You can find more information on the Python online module documents available from. This includes flags, version, max sizes of integers, available modules, path hooks, location of standard error/in/out, and command line arguments called by the interpreter. The built-in sys module provides access to objects used or maintained by the Python interpreter.

Next, we print the result, joining the text together using the concatenation operator, a plus sign, to join our variable to the rest of the text. In line two, we assign our name to a variable called user. It gives the path to the Python executable that will run our program. This line is typically not required for scripts written in Windows, but for cross-compatibility it is acceptable to include it regardless of platform. Line one defines this as a Python script.

Copy the following code into a text editor and save it as hello.py: Let's get comfortable with Python by writing a quick and simple script. If two spaces are used to indent the first time, two spaces should be used to indent subsequently. How much space is used is not typically important, as long as it is consistent. The Python interpreter uses whitespace indentation to determine which pieces of code are grouped together in a special way - for example, as part of a function, loop, or class. Formatting Python filesįormatting is important in Python. To use Kate, try typing kate hello.py to create a simple script. For example, hello.py might be our first script. In addition to having syntax highlighting, Kate handles automatic indentation, making it easier to avoid whitespace inconsistencies that could cause Python to fail. For those who do not already have an editor of choice, the Kate editor that was demonstrated in Chapter 1 has a graphical user interface (GUI) and is simple to use. As long as the indentation is consistent, Python won't mind. Text editors are a matter of personal preference. We want to create Python files in a text editor.
