Method # 1: Using a shortcut

 ` # Python code for demonstration ` ` # how to reverse the numpy array ` ` # using the shortcut `   ` import ` ` numpy as np ` ` `  ` # numpy array initialization ` ` ini_array ` ` = ` ` np.array ([` ` 1 ` `, ` ` 2 ` `, ` ` 3 ` `, ` ` 6 ` `, ` ` 4 ` `, ` ` 5 ` ])   ` # print the initial ini_array ` ` print ` ` (` ` "initial array" ` `, ` ` str ` ` (ini_array)) `   ` # print type ini_array ` ` print ` ` (` ` "type of ini_array" ` `, ` ` type ` ` (ini_array)) `   ` # using the shortcut method for reverse ` ` res ` ` = ini_array [:: - 1 ] ``   # print result print ( "final array" , str (res)) `

Exit:

` initial array [1 2 3 6 4 5] type of ini_array & lt; class `numpy.ndarray` & gt; final array [5 4 6 3 2 1] `

Method # 2: Using the `flipud`

 ` # Python code for demonstration ` ` # how to reverse the numpy array ` ` # using flipud method `   ` import ` ` numpy as np `   ` # numpy array initialization `` ini_array = np.array ([ 1 , 2 , 3 , 6 , 4 , 5 ])   # print the initial ini_array print ( "initial array" , str (ini_array))   # print type ini_array print ( " type of ini_array " , type (ini_array))   # using the flipud method to reverse res = np.flipud (ini_array)    # print result print ( "final array" , str (res)) `

Exit :

` initial array [1 2 3 6 4 5] type of ini_array & lt; class `numpy.ndarray` & gt; final array [5 4 6 3 2 1] `
