Re: alphanumeric list
string = EE472B t = [] for x in string[:]: print t.append(A) #i don't want to append A, the final result is EAEA4A7A2ABA As it, it prints None 6 times. Then t is ['A','A','A','A','A'] What you have to do is to read about basic python. Search for python tutorial on the net. Then try the following exercices : Exercises 1 print the first 1000 intergers 2 print the sine of 1 ... 1000 3 print the intergers x between 1 and 1000 such that cos(x) is between 0 and 0.5 Have a good afternoon Laurent -- http://mail.python.org/mailman/listinfo/python-list

Do u have some suggestion? thanks a lot
hi
I'm not an experienced python programmer but the following code should
work:
# you need to import the random module to get random numbers
import random
# convert the string in a list (as string are read-only)
l = list('EE472A86441AF2E629DE360')
# initialize the random generator
random.seed()
# index
i = 0
# loop through the characters in the list
for c in l:
# if the current character is a digit
if c.isdigit():
# get a random integer in the 0-9 range
# convert it to a string and replace the old value
l[i] = str(random.randint(0,9))
# increment the list index
i +=1
# convert the modified list back to string and display it
print(''.join(l))

Hi all, I would like to put an alphanumeric string like this one EE472A86441AF2E629DE360 in a list, then iterate inside the entire string lenght and change each digit with a random digit. Do u have some suggestion? thanks a lot -- http://mail.python.org/mailman/listinfo/python-list

What does change each digit with a random digit? Do you want to swap two random elements of the sequence with each other? The random module contains a tool to generate random permutations, all you would have to do is to split the string into a list, call that function and later join the results.

The thing on the right-hand side of the assignment is just the identifier EE47... after stripping the brackets, which don't have a meaning there. I'd suggest that you start reading a Python tutorial to get some basics down first. Start reading at http://docs.python.org.
