You can just iterate over the .txt file lines and check if the line is valid, by checking if = is present in the line and then simply split() the line to get the key and value pair as:

kv_store = {}

with open("./file_path.txt", "r") as f:
    for line in f.readlines():
        # Strip any `\n` etc.
        line = line.strip()

        # Check if the line contains a key, value pair
        if len(line) > 0 and line.find("=") > 0:
            key, value = line.split("=", 1)
            kv_store[key] = value.strip('"')
print kv_store
