Methods for implementing string types and dictionary types in Python _python

In this paper, the method of converting the string type to the dictionary type in Python is described as an example, which is a more practical function. The specific methods are as follows:

A dictionary (dict) to a string (string)

We can easily convert a dictionary (dict) type to a string (string) type.

You can implement dictionary to string conversions by traversing all the elements in Dict:

For key, value in Sample_dic.items ():
  print "\%s\": \ "%s\" "% (key, value)

Strings (string) to Dictionary (dict)

How do I convert a string (a) to a dictionary (dict)?

It's also very simple, as long as the eval () or EXEC () functions are implemented.

>>> a = "{' A ': ' Hi ', ' B ': ' There '}"
>>> B = eval (a)
>>> b
{' A ': ' Hi ', ' B ': ' There '}
>>> exec ("c=" + a)
>>> c
{' A ': ' Hi ', ' B ': ' There '}
>>>
