Several ways Python converts a string into a dictionary

When we encounter a string similar to {' A ': 1, ' B ': 2, ' C ': 3}, and you want to convert it to a dictionary for processing, you can use the following methods:

1. Python's own eval function (unsafe)

' {"a": 1, "B":2, "C": {"D":1}} '  = eval (dictstr)

2. Using the AST module's Literal_eval function (secure)

' {"a": 1, "B":2, "C": {"D":1}} '  = Ast.literal_eval (DICTSTR)

3. Using the loads function of the JSON module

Dictstr = ' {' A ': 1, ' B ': 2, ' C ': {' d ': 1} ' mydict = Json.loads (DICTSTR)

Make the dictionary orderly

 from Import  '{' A ': 1, ' B ': 2, ' C ': 3}'# Returns a class object that can continue processing
