try:
something_invalid()
except Exception as e:
print(exception_to_string(e))

Parse a .py file, read the AST, modify it, then write back the modified source code
...at would enable you do do so.
eg.
import ast
import codegen
expr="""
def foo():
print("hello world")
"""
p=ast.parse(expr)
p.body[0].body = [ ast.parse("return 42").body[0] ] # Replace function body with "return 42"
