queue = Queue[int]() queue.push("three") queue.push(12) print(queue.pop() + "twelve") Here, you instantiate an integer queue, but then you push a string element to the front of the queue. While the code looks a bit troubling, it runs and produces a result:Shell $ python generi...
For example, a FLOAT type data is represented as a 8-byte IEEE-754 floating point number (fixed-width) in binary format, and a human-readable string (variable-width) in text format. The text format of values is whatever strings are produced and accepted by the input/output conversion ...
