Description:
 def putkeyword(self, keyword, value, makesubrecord=False):
 """Put the value of a table keyword. The value of a keyword can be a: - scalar which can be given a normal python scalar or numpy scalar. - an array which can be given as a numpy array. A 1-dimensional array can also be given as a sequence (tuple or list). - a reference to a table which can be given as a table object or as a string containing its name prefixed by 'Table :'. - a struct which can be given as a dict. A struct is fully nestable, thus each field in the dict can be one of the values described here. The only exception is that a table value can only be given by the string. If the keyword already exists, the type of the new value should match the existing one (e.g. a scalar cannot be replaced by an array). Similar to method :func:`getkeyword` a keyword name can be given consisting of multiple parts separated by dots. This represents nested structs, thus puts the value into a field in a struct (in a struct, etc.). If `makesubrecord=True` structs will be created for the keyword name parts that do not exist. Instead of a keyword name an index can be given which returns the value of the i-th keyword. """
