参数 :
new_shape : [tuple of ints, or n ints] 调整后阵列的形状。
refcheck : [bool, optional] 如果是False，引用计数将不被检查。默认为真。

返回：无

代码#1：

# Python program explaining
# numpy.ndarray.resize() function
        
# importing numpy as geek 
import numpy as geek 
    
arr = geek.array([[0, 1], [2, 3]])
  
# this function change the shape and size
# of the array & return None
gfg = arr.resize((2, 1))
  
print (gfg)

输出 :

None
