Help with nested list

rajasankar

Hi,

I need help creating nested lists

my code follows

Expand|Select|Wrap|Line Numbers

 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:

Expand|Select|Wrap|Line Numbers

 >>> 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.

Expand|Select|Wrap|Line Numbers

 >>> 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.
