我在一个文件夹中有 300 多个文件，每个文件包含以下形式的 3000 多个字典：
{"vol":0.625,"view100":7732,"view50":7732,"view0":7732,"mView100":7732,"mView50":7732,"mView0":7732,"posTop":0,"posBottom":768,"posRight":1024,"posLeft":0,"audio":7732,"inView":1.0,"dur":15070,"full":true,"play":7732,"platform":"ias_i2","timestamp":1519693191,"gmMeasure":true,"gmm":4,"gdr":1,"impId":1861913361,"advId":13505389,"campId":2214346458,"grpId":4532473096,"creativeId":138222749951,"skip":false,"event":"fully_viewable_audible_half_duration_impression","auc":"r","pos":2,"ua":"com.google.ios.youtube/13.06.9 (iPad6,11; U; CPU iOS 11_2_1 like Mac OS X;en_US)","ip":"96.3.52.188","time":1519693200574,"sourceId":2,"channel":"tab","appServerName":"pm01.dal.303net.pvt","doNotTrack":false,"s2s":0}

我需要提取一个特定的 K,V 对，可以说并将包含该对的整个字典存储在 python 的 txt 文件中。
这是我尝试过的：
people = [ {'name': "Tom", 'age': 10}, {'name': "Mark", 'age': 5}, {'name': "Pam", 'age': 7} ]
def search(name):
for p in people:
if p['name'] == name:
return p search("Pam")
有没有简单的方法来做到这一点？
这里有两个不同的问题：
该fileinput模块可以解决第一部分，json 模块可以转换 Python dict 中的每一行，并且您已经拥有在 dict 中搜索键值对的代码。
所以假设filelist包含相关文件的路径（glob模块可以帮助构建它......）：
for line in fileinput.fileinput(filelist):
if len(line.strip()) != 0: # skip eventual empty lines...
cur = json.loads(line)
if cur[key] == value:
# line contains the text for the dictionary, cur contains the dictionary itself
# fileinput.filename() contains the name of the file
# fileinput.filelineno() is the current line
# for example
print("Found", key, "->", value, "in", fileinput.filename(),
"at line", fileinput.filelineno(), ":\n", line)
