def build_profile(first, last, **user_info):

print(user_profile)
In the user_profile variable I am not allowed (by Python) to write 'location':'princeton' and 'field': 'physics'. That's the structure of key-value-pairs, isn't it? Why can't I then use it, but am submitted by the IDLE to use =, and remove single-quotation marks which are in dictionaries used for assigning values.
