Hi,

I believe the parser module <https://docs.python.org/3/library/parser.html> allows for generation of a CST, though the documentation is not specific about the type of syntax tree used. The old compiler module <https://docs.python.org/2/library/compiler.html> utilized it for this purpose and contains explicit documentation about getting a CST from the parser module.

Hello, everyone.

I'm learning python source code, I used to print info when I debug code, but it's not convenient. I want to print CST, AST, ByteCode with iPython, wirte some code, then print it's CST、AST、 BYTECODE, and then to read the source code. But, I can't dump the CST tree which will transform to AST, I know I can print CST tree by modifying python source code, but how to dump the CST tree in iPython just like dumping AST with ast package. 1. get AST with ast package2. get ByteCode with dis package 3. but how get cst??
