here is the sample code
>>> import itertools
>>> import string
>>> var=[]
>>> for i in string.ascii_lowercase[0:5]:
var.append(i)
>>>print var
['a', 'b', 'c', 'd', 'e']
>>> length=int(raw_input("enter the length of random letters you need "))
enter the length of random letters you need 2
the user gave two so code should be like this
>>>for i in itertools.product(var,var):
print i[0]+i[1]
output of code should be like this
aa
ab
ac
ad
ae
ba
bb
bc
bd
be
ca
cb
cc
cd
ce
da
db
dc
dd
de
ea
eb
ec
ed
ee
based on the user given input of length i need to add var in for loop
if 3 given
>>>for i in itertools.product(var,var,var):
print i[0]+i[1]+i[2]
if 4 given
>>>for i in itertools.product(var,var,var,var):
print i[0]+i[1]+i[2]+i[3]
like this i need to get
i tried var*length
>>>print var
['a', 'b', 'c', 'd', 'e']
>>> var*length
['a', 'b', 'c', 'd', 'e', 'a', 'b', 'c', 'd', 'e']
if i use the same in for loop
>>>for i in itertools.product(var*2):
print i[0]+i[1]
Traceback (most recent call last):
File "<pyshell#16>", line 2, in <module>
print i[0]+i[1]
IndexError: tuple index out of range
so i need to use many if blocks based on user input which makes my code
very lengthy
thanks in advance
