How do I create a file-like object (same duck type as File) with the contents of a string?

The preferred way of wrapping long lines is by using Python's implied line continuation inside parentheses, brackets and braces. If necessary, you can add an extra pair of parentheses around an expression, but sometimes using a backslash looks better. Make sure to indent the continued line appropriately.
You can use the :> , :< or :^ option in the f-format to left align, right align or center align the text that you want to format. We can use the fortmat() string function in python to output the desired text in the order we want.
To create a file object in Python use the built-in functions, such as open() and os. popen() . IOError exception is raised when a file object is misused, or file operation fails for an I/O-related reason. For example, when you try to write to a file when a file is opened in read-only mode.
For Python 2.x, use the StringIO module. For example:
>>> from cStringIO import StringIO >>> f = StringIO('foo') >>> f.read() 'foo' I use cStringIO (which is faster), but note that it doesn't accept Unicode strings that cannot be encoded as plain ASCII strings. (You can switch to StringIO by changing "from cStringIO" to "from StringIO".)
For Python 3.x, use the io module.
f = io.StringIO('foo') If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
