Adressing part of a string via the array syntax in Python

Question

Is it, in Python, possible to adress a specific character in a string by the standard array syntax?

Example, PHP:

$foo = 'bar';
echo $foo[1]; // Output: a

It didn't work like in PHP so I wanted to know if it is possible using some other way

Answer 1

As Adam pointed out, reading from a string array is possible in Python using the indexing syntax. What isn't possible though is writing to a string using this syntax:

>>> s = 'bar'
>>> s[2] = 'z'
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
TypeError: 'str' object does not support item assignment

Maybe this was the problem you ran into?

Answer 2

Yes, this works. In fact, it works exactly like it does in PHP. The only difference is that variable names in Python are not preceeded by the $ character.

foo = 'bar'
print foo[1] # Output: a

Is Python, strings are one of a number of sequence types. You can find all of the operations that you can perform on sequence types in the Python documentation.
