[FIXED] add characters of a string to an empty string

Issue

I'm trying to copy the characters entered by the user to an empty string. If the user enters 'xt', it will terminate. Here is what I have done:

z=raw_input("ent")
d=''
for j in range(len(z)):
    d+=z[j]
    if(d=="xt"):
        break

However, I get an error.

IndexError: string index out of range

Solution

Try looping through the string itself:

z=raw_input("ent")
d=''
for j in z:
    d+=j
    if d=="xt":
        break
