specifying the number of significant digitsįormats can get rather complicated, as they use a mini-language to specify all of the details.įor more information about format specification, read this.specifying if the numbers are integers or floats.There are several options for this, including: The fmt parameter enables you to specify a format that you want to use for your data in the saved text file. So instead of a Numpy array, you can also provide a Python list or similar array-like object. However, technically, np.savetxt will accept any “array like” object. Most frequently, the input will be a Numpy array. The array argument is the data that you want to save. gz, Numpy savetxt will automatically save the file in a compressed format. Note that if the name you provide ends in. What that means is that the np.savetxt() function assumes that the first input to the function is the name of the output file. Importantly, this argument only works as a positional argument. The filename argument is the first input to Numpy savetxt.Īs noted above, this is the name of the output file.

Let’s look at each of them one at a time. Numpy savetxt has several arguments and optional parameters. The Parameters and Inputs of Numpy Savetxt Then, there are some optional parameters that you can use that will modify how exactly the function works. The second argument is the Numpy array that you want to save. The first argument to the function is the filename that you want to use for the output text file. np.savetxt syntaxĪt a high level, the syntax of Numpy savetxt is simple.Īssuming that you’ve imported the Numpy package as I explained above, you can type the function as np.savetxt.

I just want to remind you of this, because going forward, I’m going to assume that you’ve imported Numpy like I just did in the code above. Said differently, how exactly we import Numpy will change the syntax slightly, because it changes the prefix that we use for the Numpy namespace. This is important, because when we import Numpy like this, it enables us to call Numpy functions with the prefix ‘ np‘. In the case of Numpy, we typically do that with the following code: Whenever we use a Python package, we need to import the package first. A quick noteīefore we jump into the syntax, I want to remind you of one detail. We’ll look at how it works at a high level, but we’ll also look at some of the optional parameters. In this section, we’ll look at the syntax of np.savetxt. So let’s quickly look at the syntax of Numpy savetxt. There are quite a few details about the function, however, that depend on the syntax. Numpy savetxt enables you to save a Numpy array to a text file. Numpy has a variety of tools for creating, reshaping, aggregating, and otherwise manipulating numeric data in Python.īut after you’ve wrangled your data, you sometimes need to save it in a format that’s suitable for long-term storage or transfer to other people. If you need something specific, you can click on any of the following links.Īs you’re probably aware, Numpy savetxt is a function from the Numpy package.

The tutorial explains what the function does, explains the syntax, and shows step-by-step examples of how to use np.savetxt. This tutorial will show you how to save your Numpy arrays to a text file using Numpy savetxt.
