Please, As its currently written, your answer is unclear. In Python, you can convert a Python int to a string using str(): By default, str() behaves like int() in that it results in a decimal representation: In this example, str() is smart enough to interpret the binary literal and convert it to a decimal string. The split () method turns a string into a list.

Did this satellite streak past the Hubble Space Telescope so close that it was out of focus? Those string are hex values. A Computer Science portal for geeks. Rather than reversing the array, we simply subtract the index from the length of x (len(x)), and minus one more so that the first element is 10000, not 100000. The following examples show how to use each method in practice with the following NumPy array of floats: The following code shows how to convert a NumPy array of floats to an array of integers in which each float is rounded down to the nearest integer: Notice that each float has been rounded down to the nearest integer and the new array has a dtype of int32. Array scalars have the same attributes and methods as ndarrays. Two possible Python data types for representing an integer are: For example, you can represent an integer using a string literal: Here, Python understands you to mean that you want to store the integer 110 as a string.
