pyyeti.nastran.bulk.nas_sscanf

pyyeti.nastran.bulk.nas_sscanf(s, keep_string=False)[source]

Read a single integer or Nastran-formatted floating point number

Parameters:

  • s (string) – May be formatted in the NASTRAN shortcut way; eg, ‘1.7-4’ instead of ‘1.7e-4’. May also use ‘d’ instead of ‘e’.

  • keep_string (bool; optional) – Only used if s is a string that cannot be interpreted as a number. In that case, if keep_string is True, s.strip() is returned; otherwise, if keep_string is False, None is returned.

Returns:

v (int or float or string or None) – The scalar value that the string represents. If string is empty, returns None. If keep_string is True, v will be s.strip() when s cannot be converted to a number.
