How can Python convert a list to an array?
In Python, there is no explicit conversion method between lists and arrays because Python’s lists are actually a type of dynamic arrays. However, if you want to use arrays from the NumPy library, you can convert a list to an array using the numpy.array() function.
First, make sure you have installed the NumPy library. Then, you can follow these steps to convert a list into an array:
- Import the NumPy library.
import numpy as np
- Create a list:
my_list = [1, 2, 3, 4, 5]
- create a new array using numpy
my_array = np.array(my_list)
Now, my_array is a NumPy array.
Additionally, if you are using the array module built in Python, you can use the array.array() function to convert a list into an array. The usage is similar to the steps mentioned above.
- Import the array module.
import array
- Create a list:
my_list = [1, 2, 3, 4, 5]
- create a new array
my_array = array.array('i', my_list)
Here, the parameter ‘i’ represents the element type of the array as an integer. You can choose different types as needed.
