- It is not that commonly used. It is used when you have Python source code in string form, and you want to make it into a Python code object that you can keep and use. Here's a trivial example: >>> codeobj = compile('x = 2nprint "X is", x', 'fakemodule', 'exec') >>> exec(codeobj) X is 2
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.

Python compile()built-in function is used to compile a source code string or a file into a code object that can be executed by the Python interpreter. The main use of the compile()function is to dynamically generate code and execute it at runtime. In this tutorial, we will learn the syntax and usage of compile()built-in function with examples.
In the following program, we will take source code in a string, compile the code using compile()built-in function, and then execute the compiled object using exec(). Python Program Output
The compile()function is commonly used in advanced Python programming scenarios, such as: 1. Creating dynamic code at runtime, such as in code generation tools or template engines. 2. Performing program analysis and optimization, such as in static analyzers or JIT (Just-In-Time) compilers. 3. Implementing custom interpreters or compilers, such as i...
In this Built-in Functions tutorial, we learned the syntax of the object()built-in function, and how to use this function to create an empty 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)
Sep 21, 2024 · The compile() function returns a code object. You can then use this code object with the exec() or eval() functions to execute the compiled code. Example 1: Compiling a Single Statement. Let's see a simple example: code_obj = compile('print("Hello, CodeLucky!")', '<string>', 'single') exec(code_obj) Output: Hello, CodeLucky!
Mar 8, 2024 · The compile() function is a built-in Python method that compiles source code into a code object which can then be executed by the exec () function. It’s valuable for creating code objects dynamically or analyzing source code statically.
Dec 23, 2020 · Python’s built-in compile() method returns an executable code object as an “Abstract Syntax Tree” represented as an ast object. By passing this code object into the exec() or eval() functions, you can run it dynamically in your Python code.
The compile() method computes the Python code from a source object and returns it. Example. codeInString = 'a = 8\nb=7\nsum=a+b\nprint("sum =",sum)' . codeObject = compile(codeInString, 'sumstring', 'exec') exec(codeObject) # Output: 15. Run Code. compile () Syntax. The syntax of compile() is: compile(source, filename, mode)
