numpy.fromiter() in Python

numpy.fromiter() in Python The fromiter() function of Python numpy class creates a ndarray by using an iterable object. It returns a one-dimensional ndarray object. Syntax

numpy.fromiter(iterable, dtype, count=-1)

Parameter The numpy.frombuffer() method consists of three parameters, which are as follows:

1. Iterable: This parameter represents an iterable object.
2. dtype: It represents the data type of the resultant array items.
3. count: This functiondepicts the number of items to read from the buffer in the specified array.

Return This function returns an array created by using the iterable object. Example 1

# Python Programming giving an example for 
# numpy.fromiter() function
importnumpy as numpy
my_list = [0,2,4,6] 
it = iter(my_list) 
n = numpy.fromiter(it, dtype = float) 
print(n) 
print(type(n))

Output

[ 0.  2.  4.  6.]
<class 'numpy.ndarray'>
