This folder contains sample code from the Real Python tutorial Expression vs Statement in Python: What's the Difference?
Identify whether a piece of Python code is an expression or a statement:
$ python code_inspector.py
Type a Python code snippet or leave empty to exit.
>>> yield
statement
>>> (yield)
expression
>>> 2 +
invalidRegister a lambda expression as a callback, which delegates to a function with statements:
$ python gui_app.pyCompile with a C compiler and pipe stdin to the echo program:
$ gcc echo.c -o echo.x
$ echo "Hello, World!" | ./echo.x
Hello, World!Read a binary file and display its bytes in hexadecimal format:
$ python hex_reader.py /path/to/HelloJava.class --columns 8
