How do you get a string in Python?

Sewing thread should be good. Heavy rope is a bad idea — lots of internal rubbing happens when it’s pulled on. The longer the string is, the more lossy it will be (again, internal friction, and also some coupling to the air), so put the cans/cups close together.
Is string a wrapper class?

Although a character is a primitive datatype, a String is a sequence of characters or a character array and is widely used for the purpose of representing a character sequence conveniently.

What are arrays in Python?
Advertisements. Array is a container which can hold a fix number of items and these items should be of the same type. Most of the data structures make use of arrays to implement their algorithms.
What kind of string is best for Cup phones?
