Mar 16, 2014 · Compile the source into a code or AST object. Code objects can be executed by an exec statement or evaluated by a call to eval(). source can either be a Unicode string, a Latin-1 encoded string or an AST object.
Nov 2, 2023 · Python compile() function takes source code as input and returns a code object that is ready to be executed and which can later be executed by the exec() function. Syntax compile(source, filename, mode, flags=0, dont_inherit=False, optimize=-1)
2 days ago · The py_compile module provides a function to generate a byte-code file from a source file, and another function used when the module source file is invoked as a script.
Sep 21, 2024 · The compile() function in Python is a powerful tool that allows you to transform source code into a code object. This process is crucial for dynamic code execution and can be utilized in various scenarios, from evaluating user-provided input to building complex dynamic systems.

Learn by example! Let’s say, you have a code file with the following content: Here’s an example on how to use the compile() built-in function. First, you create the code as a string. Second, you pass the string into the compile() function to create an ast object. You can then pass this object into the exec()function and run it dynamically.
Before you dive into the syntax, you may not be motivated to use the compile() function in the first place. Why? Because you can also use the exec()function on a string instead of a code object. Python’s exec() function executes the Python code you pass as a string or executable object argument. This is called dynamic execution because, in contrast...
Consider the following interactive code: Exercise: Print the number associated to Alice in the dictionary! Check out my new Python book Python One-Liners(Amazon Link). If you like one-liners, you’ll LOVE the book. It’ll teach you everything there is to know about a single line of Python code. But it’s also an introduction to computer science, data ...
Say, you have the following code in a code file: How to read the code from a file, compile it, and execute it at runtime? Here’s the code: Alternatively, you can also use the following one-liner to read the code from a file: Frankly, I don’t see a huge problem with not closing the file if you have a small script and you don’t access the file anywhe...
The Python compile() method returns an executable code object as an “Abstract Syntax Tree” that is represented as an astobject. There are many applications of an ast such as the following: You can pass this code object into the exec() or eval()functions and run it dynamically in your Python code. This way, you can programmatically create source cod...
Enough theory. Let’s get some practice! Coders get paid six figures and more because they can solve problems more effectively using machine intelligence and automation. To become more successful in coding, solve more real problems for real people. That’s how you polish the skills you really need in practice. After all, what’s the use of learning th...
Jun 12, 2023 · To compile the Python code from the my_program.py file, we can use the compile () function as follows: filename = 'my_program.py' with open(filename) as file: source_code = file.read() compiled_code = compile(source_code, filename, 'exec') exec(compiled_code) In this example, we open the my_program.py file using the open () function, read its ...
