Python numpy.defchararray.capitalize()

numpy.core.defchararray.multiply(arr, n):将字符串的第一个字母按元素大写。

参数:
arr :类似数组或字符串。

返回值 :大写的字符串的第一个字母。

代码 #1:

# Python Program illustrating 
# numpy.char.capitalize() method 
import numpy as np 
  
arr1 = ['eAAAaeAAAa', 'ttttdsttttds', 'AAtAAt']
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 
# numpy.char.capitalize() method 
import numpy as np 
  
arr1 = 'this is geeks '
arr2 = 'for geeks '
  
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 :  this is geeks 
arr2 :  for geeks 

Arrays after using capitalize():
arr1 :  This is geeks 
arr2 :  For geeks
