| Try to change the block so that it prints out the information only for verbs. (You need to look at attribute ''tag'' at the ''m'' level). The tagset used is Penn Treebank Tagset. | Try to change the block so that it prints out the information only for verbs. (You need to look at an attribute ''tag'' at the ''m'' level).

Mostly, these do not differ. | //Note//: ''get_children()'' returns topological node children in a tree, while ''get_eff_children()'' returns node children in a linguistic sense.
