As title ,I web crawler the diigo , and have many list, I become the list to the set().Like this:

data = [ ['spanish', 'web2.0', 'e-learning', 'education', 'social', 'spain', 'tools', 'learning', 'google', 'e-learning2.0'],   ['education', 'technology', 'learning', 'classroom', 'students', 'web2.0'], ['education'],  ['technology'] ]

And doing something calculate

search_table = {}

for i, tag_list in enumerate(data):
    for tag in tag_list:
        if tag not in search_table:
            search_table[tag] = set()
        search_table[tag].add(i)  

# How many people have `technology`?
print(len(search_table["technology"]))
# How many people have `education`?
print(len(search_table["education"]))
# How many people have both `technology`, `education`?
print(len(search_table["technology"] & search_table["education"]))

data have many tags, i want to do this ->print(len(search_table["technology"]))<- technology can auto change next world like classroom.

i realy don't konw how to do,i only think is

for u in user_data:

   print u

but how to add the world to print(len(search_table[" u "]))

I think I understand what you mean. You were nearly there:

user_data = ["technology", "classroom"]
for u in user_data:
    print(len(search_table[u]))

will first print the number of items in search_table["technology"] and then print the number of items in search_table["classroom"].
