probably elementary but printing the actual name of the pandas variable, not the dataframe itself

feel like this is a really easy question but my brain is fried.

if i have a couple variables that contain pandas series, how can i reference the variable names themselves instead of the contents, when i try to print. Here's what's going on.

first = pd.Series({1:2, 2:4})
second = pd.Series({1:5, 2:7})
all = [first, second]

for i in all:
    print i, 'has a sum of', i.sum()

this currently prints the whole dataframe for each variable. how do i end up with an output like :

"first has a sum of 6

second has a sum of 12"

Personally I'd use a dict:

In [15]:
first = pd.Series({1:2, 2:4})
second = pd.Series({1:5, 2:7})
d={}
d['first']=first
d['second']=second
​
for k,v in d.items():
    print(k, 'has a sum of', v.sum())

output:

first has a sum of 6
second has a sum of 12

Also don't use a variable name of all this shadows the function all

EDIT

If the order matters then you can use an OrderedDict:

In [20]:

from collections import OrderedDict
first = pd.Series({1:2, 2:4})
second = pd.Series({1:5, 2:7})
d=OrderedDict()
d['first']=first
d['second']=second
​
for k,v in d.items():
    print(k, 'has a sum of', v.sum())
first has a sum of 6
second has a sum of 12
