collecting data from dataframe to another

Question

I got a DataFrame called base like the following

number   act
12       yes
33       zero
24       cool
53       loop

and another DataFrame called info like:

source   name    age
12       ashe    23
4        man     45
23       mark    12
33       john    34

I need to do the following, ‍‍‍‍‍if base["number"] == info["source"], I want to create a new DataFrame be like:

number   name   age  
12       ashe   23
33       john   34

what can be done?
