Dtypes define how data is stored in memory—its type (integer, float, etc. In this blog, we’ll demystify why `b''` appears in `savetxt ()` output, explore common scenarios where this happens, and provide step-by-step solutions to strip these byte markers. Below we describe how to work with both fixed-width and variable-width string arrays, how to convert between the two representations, and provide some advice for most efficiently working with string data in NumPy. It describes the following aspects of the data: Type of the data (integer, float, Python object, etc. Unicode strings, combined with NumPy’s default data type handling for strings.

Working with Arrays of Strings And Bytes # While NumPy is primarily a numerical library, it is often convenient to work with NumPy arrays of strings or bytes. At the heart of NumPy’s efficiency lies its handling of arrays, and a critical component of array behavior is the **dtype** (data type). ) Size of the data (how many bytes is in e. This approximates numpy 1. If you’ve worked with NumPy This is not a bug in NumPy but a result of how Python handles byte strings vs. The array is of size [1200,8] but the data is repeated along the largest dimension so I only really need to convert one row to a string. decode('utf-8') to obtain the array as a human-readable string. decode() method.
