To split a dictionary by its values, we can use a Python function that iterates over the key-value pairs in the dictionary and groups them based on their values. Here is a sample function that achieves this: defsplit_dict_by_value(input_dict):output_dict={}forkey,valueininput_dict.item...
Iterate through keys and values in dictionaries Describe related information of an object using a bunch of key-value pair In a complex scenario put many dict in a list, iterating each of elemen for the same operation card_list = [{"name":"张三", ...
