convert list to array python code example

Example 1: numpy list to array

# importing library 
import numpy  
  
# initilizing list 
lst = [1, 7, 0, 6, 2, 5, 6] 
  
# converting list to array 
arr = numpy.array(lst) 
  
# displaying list 
print ("List: ", lst) 
  
# displaying array 
print ("Array: ", arr)

Example 2: convert list to array python

import numpy as np
my_list = [2,4,6,8,10]
my_array = np.array(my_list)
# printing my_array
print my_array
# printing the type of my_array
print type(my_array)

Example 3: python convert list of lists to array

# Basic syntax:
numpy.array(list_of_lists)

# Example usage:
import numpy as np
list_of_lists = [[1, 2, 3], [4, 5, 6]] # Create list of lists
your_array = np.array(list_of_lists) # Convert list of lists to array
your_array
--> array([[1, 2, 3],
           [4, 5, 6]])

Example 4: python array to list

a = np.array([1, 2])
list(a)

Example 5: how to create an array from a list in python

def tips_unfold(fn, seed):
  def fn_generator(val):
    while True: 
      val = fn(val[1])
      if val == False: break
      yield val[0]
  return [i for i in fn_generator([None, seed])]

f = lambda n: False if n > 50 else [-n, n + 10]
print(tips_unfold(f, 10))
