arr2 = ['11sf', 'sdsf2', '1111f2']
print ("arr1:", arr1)
print ("arr2:", arr2)
Print("\nArrays after using capitalize():")
print ("\narr1:", np.char.capitalize(arr1))
print ("arr2:", np.char.capitalize(arr2))输出：
arr1: ['eAAAaeAAAa', 'ttttdsttttds', 'AAtAAt'] arr2: ['11sf', 'sdsf2', '1111f2'] Arrays after using capitalize(): arr1: ['Eaaaaeaaaa' 'Ttttdsttttds' 'Aataat'] arr2: ['11sf' 'Sdsf2' '1111f2']
代码2：
# Python Program illustrating

arr1 = 'this is geeks '
arr2 = 'for geeks '
print ("arr1:", arr1)
print ("arr2:", arr2)
Print("\nArrays after using capitalize():")
print ("\narr1:", np.char.capitalize(arr1))
