Writelines does not separate the strings, so the output will be "allenhello world. Each Class defines the specific set of data and the specific procedures that will make a particular Object.
How to write to a specific line in python
If the end of the file has been reached, f. One question remains, of course: how do you convert values to strings? The str function is meant to return representations of values which are fairly human-readable, while repr is meant to generate representations which can be read by the interpreter or will force a SyntaxError if there is no equivalent syntax.
This makes the return value unambiguous; if f. As such, it is specific to Python and cannot be used to communicate with applications written in other languages.
Objects Typical Objects can be things that appear on the screen e. This makes the return value unambiguous; if f.
Between serializing and deserializing, the string representing the object may have been stored in a file or data, or sent over a network connection to some distant machine.
This example demonstrates the str. If you really want truncation you can always add a slice operation, as in x. Many programmers are already familiar with it, which makes it a good choice for interoperability. If you have a sequence of strings you can write them all using writelines.
