Help with nested list

[rajasankar]

Hi,

I need help creating nested lists

my code follows

test = ["a","b","c"]
testtwo = ["e","f","g"]
 
mo = []
for i in range (0,len(test)):
    for j in range(0,len(testweb)):
         moa = test[i]+testweb[j]
         mo.append[moa]

I want final output like this

mo[ae[],af[],ag[],be[], ....... cg[]] instead of mo[ae,af,ag,be, ....... cg]

How to get this??? I've searched in this forum and couldn't find an answer.

Thanks,
Rajasankar

Your desired output is invalid. The brackets '[]' represent a slice object. What you are wanting is similar to:

>>> s = slice(10,20)
>>> s.indices(15)
(10, 15, 1)
>>> s.indices()
Traceback (most recent call last):
  File "<interactive input>", line 1, in ?
TypeError: indices() takes exactly one argument (0 given)
>>> 

You may want a dictionary with empty lists as values.

>>> test = ["a","b","c"]
>>> testtwo = ["e","f","g"]
>>> mo = {}
>>> for i in test:
...     for j in testtwo:
...         mo.setdefault(i+j, [])
...         
[]
[]
[]
[]
[]
[]
[]
[]
[]
>>> mo
{'be': [], 'bf': [], 'bg': [], 'ae': [], 'ag': [], 'af': [], 'cg': [], 'cf': [], 'ce': []}
>>>

Hi,

Thanks for this info. I used the dict in Python and it worked.

Thanks again.
