decompile

✓ from ast_decompiler import decompile

Library is imported as ast_decompiler, not ast-decompiler or astdecompiler.

Parses Python code into AST using the standard library, then decompiles it back to Python source code using ast_decompiler.

import ast from ast_decompiler import decompile code = """def hello(name): return f'Hello, {name}!' """ tree = ast.parse(code) reconstructed = decompile(tree) print(reconstructed) # Output: def hello(name): # return f'Hello, {name}!'

Debug

Known issues

gotchaThe import path is `ast_decompiler`, not `ast-decompiler` (with hyphen). Using `import ast-decompiler` will cause a syntax error.

fix

Use `from ast_decompiler import decompile` or `import ast_decompiler`.

affects: all

gotchadecompile() expects an AST node, not a string. Passing a string will raise AttributeError or TypeError.

fix

Always parse code with ast.parse() first: tree = ast.parse(code); decompile(tree).

affects: all

deprecatedThe old function name `decompile_to_code` may exist in very early versions or forks. It is deprecated in favor of `decompile`.

fix

Use `decompile` instead.

affects: < 0.6.0 (if applicable)

Errors

Common errors & fixes

ModuleNotFoundError: No module named 'ast_decompiler'

You have not installed the package, or you installed it under a different virtual environment.

fix

Run `pip install ast-decompiler`, ensure you are in the correct virtual environment or use `pip3` if needed.

AttributeError: module 'ast_decompiler' has no attribute 'decompile_to_code'

You are using an outdated function name. The function was renamed or removed.

fix

Use `decompile` instead: `from ast_decompiler import decompile`.

AttributeError: 'str' object has no attribute 'body'

You passed a string to decompile() instead of an AST node.

fix

Parse the string first with `ast.parse()`: `tree = ast.parse(code)`, then `decompile(tree)`.
