termination character of string in python

is there any termination character like '\0' in C for string in python? we can print the string character by character using the following code in C.

while (ch[c] != '\0')
{
   putchar(ch[c]);
   c++;
}

If you would like to loop through the string, you can use a for loop.

import sys
for c in ch:
    sys.stdout.write(c)

but, this works just as well, except it adds a new line

print ch

This doesn't print a new line (but does add a space)

print ch,

If you need the index, you can do any of the above, but in an enumerated fashion.

for i, c in enumerate(ch):
    print i, c

This gives:

0 a  
1 b  
2 c  
3 d

For a more c-like approach, which isn't recommended, you can do this:

ch = "abcd"
i = 0
while i < len(ch):
    ch[i]
    i += 1

In python, a string is an object. It comes with attributes and methods. You cannot really compare this to a C char* which is basically just a memory address.

You can use the len(...) function on a string object to know its length and do whatever you want about it.

Python string is not nul-terminated.

Why don't you just the string?

>>> ch = 'abcd'
>>> print(ch)
abcd
