NumPy arrays are used to store lists of numerical data and to If you just have a numpy array then why not convert it to a string directly for writing to your file? You can do this using str. import numpy as np numpy. Then, print(*a, sep=', ', end=' ') unpacks the list a and prints each element with a comma and space Note NumPy slicing creates a view instead of a copy as in the case of built-in Python sequences such as string, tuple and list. squeeze might be the preferred method to do this. For example: Since NumPy arrays underly Pandas dataframes, you will NumPy is a powerful Python library for handling large, multi-dimensional arrays. array_repr(arr, max_line_width=None, precision=None, suppress_small=None) [source] # Return the string representation of an array.
