creating Dict, how to update when looping

i am looping through a file directory, when i come across a file with some specific text i want to add the file name and modified time to a dictionary, based on my dir i should end up with 7 key, value pairs in my dict.

how do i keep adding key,value pairs to my dict while i loop this dir? thanks

import os
import stat

path =r"C:\Users\Gronk\Downloads"

for file in os.listdir(path):
    if 'ConsensusData' in file:
        info = os.stat( path+"\\"+file)
        t = info.st_atime
        x = {}
        x.update({file:t})

you can use setdefault method:

x = {}
for file in os.listdir(path):
    if 'ConsensusData' in file:
        info = os.stat( path+"\\"+file)
        t = info.st_atime
        x.setdefault(file, t)

Define the dictionary outside the for loop, and add key/value pairs as dict[key]=value:

x = {}
for file in os.listdir(path):
    if 'ConsensusData' in file:
        info = os.stat( path+"\\"+file)
        t = info.st_atime
        x[file] = t
