[英]how to read specific JSON files using python glob
i have a set of JSON files in a folder.我在一个文件夹中有一组 JSON 个文件。
Sample files:示例文件:
-2022_06_13_07_14_f71cd512135bdab9.json
-2022_06_13_07_1421_f71cd512135bdab9.json
-2022_06_13_07_12314_f71cd512135bdab9.json
-2022_06_14_132_14_f71cd512135bdab9.json
-2022_06_14_74647_14_f71cd512135bdab9.json
Instead of reading all files at once, I need to read them day-wise.我不需要一次阅读所有文件,而是需要每天阅读它们。
ex:2022_06_13_07_14_f71cd512135bdab9.json corresponding to 2022_06_13.例如:2022_06_13_07_14_f71cd512135bdab9.json 对应 2022_06_13。
like wise I need to read all the JSON files and do the changes in Daywise batches.同样,我需要阅读所有 JSON 文件并在 Daywise 批次中进行更改。
read all JSON files in 2022_06_13 first then all the JSON files in 2022_06_14 and so on.首先读取 2022_06_13 中的所有 JSON 个文件,然后读取 2022_06_14 中的所有 JSON 个文件,依此类推。 i thought to apply wildcard with looping day wise list.我想在循环日明智列表中应用通配符。
my issue with the below line.我对以下行的问题。 How do I add a wild card to find all JSON files related to a particular date?如何添加通配符以查找与特定日期相关的所有 JSON 文件?
json_files = glob.glob(os.path.join(path_to_json, 'day*.json'))
current code:当前代码:
start = datetime.datetime(2022, 8, 25)
end = datetime.datetime(2022, 12, 25)
datelist = pd.date_range(start, end)
path_to_json = r'C:\Users\Admin\INPUT'
for a in datelist:
day=str(a)[:10].replace('-', '_')
json_files = glob.glob(os.path.join(path_to_json, 'day*.json'))
for i in json_files:
with open(i,'r') as fi:
dict = json.load(fi)
dict[0]["Name"] = "NETFLIX"
fi.close()
l= i.rsplit('\\', 1)[1]
Output_URL="C:\\Users\\Admin\\OUTPUT\\Netflix\\"+l
with open(Output_URL, "w+") as f:
json.dump(data, f)
Change this: json_files = glob.glob(os.path.join(path_to_json, 'day*.json'))
改变这个: json_files = glob.glob(os.path.join(path_to_json, 'day*.json'))
to this: json_files = glob.glob(os.path.join(path_to_json, f"{a.strftime('%Y_%m_%d')}*.json"))
为此: json_files = glob.glob(os.path.join(path_to_json, f"{a.strftime('%Y_%m_%d')}*.json"))
This will take date a
and turn it into a string that is similar to the one in your files.这将采用日期a
并将其转换为类似于文件中的字符串。 Leave the asterisk after it as a wildcard and you should get all files that match date a
everytime.将星号作为通配符保留在它后面,您应该每次都获得与日期匹配a
所有文件。
