#!/usr/bin/env python # coding: utf-8 # # StringIO # # The StringIO module implements an in-memory file like object. This object can then be used as input or output to most functions that would expect a standard file object. # # The best way to show this is by example: # In[1]: import StringIO # In[16]: # Arbitrary String message = 'This is just a normal string.' # In[25]: # Use StringIO method to set as file object f = StringIO.StringIO(message) # Now we have an object *f* that we will be able to treat just like a file. For example: # In[30]: f.read() # We can also write to it: # In[27]: f.write(' Second line written to file like object') # In[28]: # Reset cursor just like you would a file f.seek(0) # In[29]: # Read again f.read() # Great! Now you've seen how we can use StringIO to turn normal strings into in-memory file objects in our code. This kind of action has various use cases, especially in web scraping cases where you want to read some string you scraped as a file. # # For more info on StringIO check out the documentation:https://docs.python.org/2/library/stringio.html
