To do this, you use Python’s index notation: a number in brackets, starting at 0, that indicates the position of the item in the list.

Furthermore, Python contains the notion of "slice-notation," meaning that the programmer can chose small sections of the string, called "substrings" to manipulate as well.

Although Julia is purpose-built for data science, whereas Python has more or less evolved into the role, Python offers some compelling advantages to the data scientist.
