[Python] Print total number of languages in data (Python assignment)

For an assignment in my 30 days Python course i have the following:

Go to the data folder and use the countries_data.py file.

What are the total number of languages in the data?

So i have tried everything, but i cant seem to write a code that returns the total number of languages. I have gotten as far as this:

for language in countries:
for key in language:
if key == ('languages'): print (key.count('languages'))


But the output only shows how many times the key languages is in the file.

I Wrote:

for language in countries:
for key in language:
if key == language: print (key.items())


I hope that someone can give me the right script.
