numpy中int类型与python中的int

import numpy as np
nparr = np.array([[1 ,2, 3, 4]])
np_int32 = nparr[0][0]   #  np_int=1
py_int = 1234
#打印类型
print("type(py_int32)="+str(type(py_int32)))  
print("type(np_int)="+str(type(np_int)))

#numpy 的int32 转 int64
np_int64=np.int64(np_int )
print("type(np_int64)="+str(type(np_int64)))

type(py_int)=<class ‘int‘>
type(np_int)=<class ‘numpy.int32‘>
type(np_int64)=<class ‘numpy.int64‘>
