 # numpy.exp2 () in Python

Parameters:

array: [array_like] Input array or object whose elements, we need to test.
out: [ndarray, optional] Output array with same dimensions as Input array,
placed with result.
** kwargs: Allows you to pass keyword variable length of argument to a function.
It is used when we want to handle named argument in a function.
where: [array_like, optional] True value means to calculate the universal
functions (ufunc) at that position, False value means to leave the
value in the output alone.

Return:

` An array with 2 ** x (power of 2) for all x ie array elements `

``` # Python program explaining  # exp2 () function import numpy as np   in_array = [ 1 , 3 , 5 , 4 ] print ( "Input array:" , in_array)   exp2_values ​​ = np.exp2 (in_array) print ( "2 ** x values:" , exp2_values) Output: Input array: [1, 3, 5, 4] 2 ** x values: [2. 8. 32. 16.] Code 2: Graphic representation # Show Python program # Graphical representation function # exp2 () import numpy as np import matplotlib.pyplot as plt   in_array = [ 1 , 2 , 3 , 4 , 5 , 6 ] out_array = np.exp2 (in_array)   print ( "out_array:" , out_array)   y = [ 1 , 2 , 3 , 4 , 5 , 6 ] plt.plot (in_array, y, color  = `blue` , marker = "*" )   # red for numpy.exp2 () plt.plot (out_array, y, color = `red` , marker = "o" ) plt.title ( "numpy.exp2 ()" ) plt.xlabel ( "X" ) plt.ylabel ( "Y" ) plt.show ()  ```

Exit:
out_array: [2. 4. 8. 16. 32. 64.]
