示例1: expect_token

# 需要导入模块: import token [as 别名]
# 或者: from token import py [as 别名]
def expect_token(token, tok_type, tok_str=None):
  """
  Verifies that the given token is of the expected type. If tok_str is given, the token string
  is verified too. If the token doesn't match, raises an informative ValueError.
  """
  if not match_token(token, tok_type, tok_str):
    raise ValueError("Expected token %s, got %s on line %s col %s" % (
      token_repr(tok_type, tok_str), str(token),
      token.start[0], token.start[1] + 1))

# These were previously defined in tokenize.py and distinguishable by being greater than
# token.N_TOKEN. As of python3.7, they are in token.py, and we check for them explicitly.
