我已将字典保存为txt文件
strstr
保存的txt文件包含
f = open("dict_imageData.txt","a")
f.write( str(dict_imageData) + "\n" )
f.close()
我在加载此字典并拆分键和值时遇到问题。我试过拆分和eval但是没有用,因为最后有一个dtype语句。
有什么建议吗?

感谢您的评论,是的我知道使用JSON和pickle,但我更感兴趣的是.txt文件。我解决了我的问题并找到了解决方案如下:
首先,我将MyEncoder类定义为:
class MyEncoder(json.JSONEncoder):
def default(self, obj):
if isinstance(obj, np.integer):
return int(obj)
elif isinstance(obj, np.floating):
return float(obj)
elif isinstance(obj, np.ndarray):
return obj.tolist()
else:
return super(MyEncoder, self).default(obj)
因为我的键是字符串而我的值是数组,所以在写入键值对之前我将值转储为
dict_imageData [key] = json.dumps(np.float32(np.array(values)), cls = MyEncoder)
现在,我将字典写为文件
with open('dict_imageData.txt', 'a') as file:
file.write(json.dumps(dict_imageData))
file.write("\n")
为了从.txt文件中读回字典,我使用eval
with open('dict_imageData.txt','r') as inf:
lineno = 0
for line in inf:
lineno = lineno + 1
print("line number in the file: ", lineno)
dicts_from_file = dict()
dicts_from_file = (eval(line))
for key,value in dicts_from_file.items():
print("key: ", key, "value: ", value)
