Can program a little or not, use office directly. Copy all the poems you need to count into this document for statistics. Use Ctrl+F to search for the words you want to count, and there are words you want to count in the upper left corner. Note that the version I use is office20 10. Other versions need to be verified.
The advanced point is to count the times of all fonts at one time by programming, but there are some technical difficulties.
Hope to adopt!
