2. ndarray转换成tuple 我们可以使用numpy的tolist()函数来将ndarray转换成tuple。下面是一个例子：```python import numpy as np arr = np.array([1, 2, 3])tup = arr.tolist()print(tup)```输出结果为：```[1, 2, 3]```在这个例子中，我们首先定义了一个ndarray类型的数据arr，然后使用了numpy的...
tuple()# 可以将list, dict, numpy.array, torch.tensor等转化为元组 >>>tuple([1, 2, 3]) (1, 2, 3) 2.list 对于我个人我而言, list是我最经常使用的数据类型, 因为总感觉list跟c语言中的数组非常相似 list的索引(带中括号[])、拼接“+”、乘法“*”、遍历以及查找都是相同的, 主要来说以下不...
在python内建对象中,数组有3种形式:列表list [1,2,3]、元组 tuple (1,2,3)、字典 dict {a:1,b:2};在numpy中使用numpy.array将列表或者元组转换为ndarray数组。 np.array(object,dtype=None,copy=True,order:None,subok=False,ndmin=0) object:输入对象列表、元组等; dtype:数据类型; copy:布尔类型,默...

使用array函数讲tuple和list转为array: 1 2 3 4 5 6 7 8 9 >>>importnumpy as np >>> a=np.array([2,3,4]) >>> a array([2,3,4]) >>> a.dtype dtype('int64') >>> b=np.array([1.2,3.5,5.1]) >>> b.dtype dtype('float64') ...
