我有一个字典dic
,其中包含一个键'Band_1'
和一个二维值数组。我想简单地从字典中提取这些值作为2D数组,但我必须保持相同的索引/结构。字典看起来像:
{'Band_1': array([[ 72284.15387234, 71911.10445312, 76238.47771614, ...,
43633.95847573, 45275.37592033, 45499.20557187],
[ 70493.51666005, 70120.46724083, 72358.76375619, ...,
40127.293935 , 39381.19509655, 38709.70614194],
[ 76238.47771614, 76238.47771614, 76238.47771614, ...,
42738.63986959, 42440.20033421, 43037.07940497],
...,
[ 45275.37592033, 45872.25499109, 45275.37592033, ...,
25727.58635285, 24309.99855979, 24384.60844364],
[ 47812.11197107, 50871.11720873, 49005.8701126 , ...,
30875.66833818, 31845.59682817, 31770.98694433],
[ 44007.00789496, 45499.20557187, 45349.98580418, ...,
26622.904959 , 28935.8113582 , 31547.15729279]])}
到目前为止,我尝试过:
for key, values in dic.iteritems():
for x in values[0]:
array.append(x)
for y in values[1]:
array.append(y)
和
for keys, values in dic.items():
array = [[y for y in values[1]] x for x in values[0]]
我需要一种有效的方法,因为数组会非常大吗?
答案 0 :(得分:1)
你的“dic”变量包含数组,当你访问它时它是键,它会被返回...
array = dic['Band_1']
给你内部数组......
正如字典中的任何其他项目一样:
dict = {'key': 'value'}
dict['key'] #returns 'value'
