SyntaxError

built-in exceptions

Syntactically invalid code, detected at compile time: eval('1 +').

Syntax

raise SyntaxError

You cannot wrap your own broken source in try/except: the whole file is parsed before anything runs, so the error fires before the first statement executes. Catching it makes sense only for code compiled at runtime — eval(), exec(), compile(), or importing third-party code. The exception carries msg, filename, lineno, offset and text for pinpointing the spot, and IndentationError and TabError are its subclasses.

Examples

try:
    eval('1 +')
except SyntaxError as e:
    print(type(e).__name__)   # → SyntaxError
