Expand description

Represents the different types of errors that can occur during lexing.

Variants§

§

UnicodeError

Decoding of a unicode escape sequence in a string literal failed.

§

NestingError

The nesting of brackets/braces/parentheses is not balanced.

§

IndentationError

The indentation is not consistent.

§

TabError

Inconsistent use of tabs and spaces.

§

TabsAfterSpaces

Encountered a tab after a space.

§

DefaultArgumentError

A non-default argument follows a default argument.

§

DuplicateArgumentError(String)

A duplicate argument was found in a function definition.

§

PositionalArgumentError

A positional argument follows a keyword argument.

§

UnpackedArgumentError

An iterable argument unpacking *args follows keyword argument unpacking **kwargs.

§

DuplicateKeywordArgumentError(String)

A keyword argument was repeated.

§

UnrecognizedToken

An unrecognized token was encountered.

Fields

§tok: char
§

FStringError(FStringErrorType)

An f-string error containing the FStringErrorType.

§

LineContinuationError

An unexpected character was encountered after a line continuation.

§

Eof

An unexpected end of file was encountered.

§

OtherError(String)

An unexpected error occurred.
