如何使用变量作为集合在MongoDB中查找文档？

Question

I want to use the following commands:

coll = sys.argv[1]
docs = db.coll.find()

That does not work. If I hardcode it like this it works:

docs = db.collection_I_want_to_query.find()

I guess the find-function does not work because coll is a string. But is there a possibility to use variables for querying?

col = sys.argv[1]
db[col].find()
