# Example 1: Convert python list to Numpy array # Using numpy.array() method arr = np.array(mylist) # Example 2: Convert python list to numpy array # Using numpy.asarray() method arr = np.asarray(mylist) # Example 3: Using numpy.asarray() method ...
If you’re working with NumPy arrays, you can convert all float elements to integers: import numpy as np float_array = np.array([1.5, 2.7, 3.9]) int_array = float_array.astype(int) print(int_array) # Output: [1 2 3] ReadHow to Read XML Files in Python?
Input numpy array: [[4 1] [7 2] [2 0]] Output Series: 0 [4, 1] 1 [7, 2] 2 [2, 0] dtype: object By using map and lambda functions together, here we have converted the two-dimensional numpy array into a series object. The data type of the converted series is an object ...
We can convert a numpy ndarray usingtostring()method and to convert this string back into the form of a numpy ndarray, we can usenumpy.fromstring()method and also we need to define the data type of the elements. Let us understand with the help of an example, ...
