I am using Python 3.2.1 and I can't import the StringIO
module. I use io.StringIO
and it works, but I can't use it with numpy
's genfromtxt
like this:
x="1 3\n 4.5 8" numpy.genfromtxt(io.StringIO(x))
I get the following error:
TypeError: Can't convert 'bytes' object to str implicitly
and when I write import StringIO
it says
ImportError: No module named 'StringIO'
The StringIO module is an in-memory file-like object. This object can be used as input or output to the most function that would expect a standard file object. When the StringIO object is created it is initialized by passing a string to the constructor. If no string is passed the StringIO will start empty.
Strings are defined as an array of characters. The difference between a character array and a string is the string is terminated with a special character '\0'. Declaration of strings: Declaring a string is as simple as declaring a one-dimensional array. Below is the basic syntax for declaring a string.
Python – Write String to Text FileOpen the text file in write mode using open() function. The function returns a file object. Call write() function on the file object, and pass the string to write() function as argument. Once all the writing is done, close the file using close() function.
when i write import StringIO it says there is no such module.
From What’s New In Python 3.0:
The
StringIO
andcStringIO
modules are gone. Instead, import theio
module and useio.StringIO
orio.BytesIO
for text and data respectively.
.
A possibly useful method of fixing some Python 2 code to also work in Python 3 (caveat emptor):
try: from StringIO import StringIO ## for Python 2 except ImportError: from io import StringIO ## for Python 3
Note: This example may be tangential to the main issue of the question and is included only as something to consider when generically addressing the missing
StringIO
module. For a more direct solution the messageTypeError: Can't convert 'bytes' object to str implicitly
, see this answer.
