Python File truncate() Method The truncate() method truncates a file to a certain size. If the optional size argument is provided, the file will be truncated to at most that size. The size defaults to the current position. The current…
Python File fileno() Method The fileno() method returns an integer file descriptor, which is used by the underlying implementation to request I/O operations from the operating system. Syntax The syntax of the fileno() method is as follows: fileObject.fileno() Parameters NA…
Python File close() Method The close() method is used to close an open file. A closed file cannot be read from or written to. If the file is closed, any operations that require the file to be open will result…
Python File writelines() Method The writelines() method writes a sequence of strings to a file. The sequence can be any iterable object, typically a list of strings. This method has no return value. Syntax The syntax of the writelines() method…
Python file readlines() method The readlines() method reads until EOF using readline() and returns a list containing the lines. If the optional sizehint parameter is present, rather than reading until EOF, a whole line of approximately sizehint bytes will be…
Python File readline() Method The readline() method reads an entire line from a file. Newline characters are preserved in the string. If the size parameter is specified and is non-negative, it represents the maximum number of bytes, including newline characters…
Python File isatty() Method The isatty() method returns True if the file is connected (associated with a terminal device) to a tty (or similar) device, otherwise it returns False. Syntax The syntax of the isatty() method is as follows −…
Python File next() Method Python 3 File objects do not support the next() method. Python 3 has a built-in function next() that retrieves the next item by calling the iterator’s next() method. If default is given, it is returned if…
Python File seek() Method The seek() method sets the current file position to an offset. The whence parameter is optional and defaults to 0, indicating absolute file positioning. Other values are 1 for relative positioning relative to the current position,…
Python File flush() Method The flush() method flushes the internal buffer, similar to stdio’s fflush. For some file-like objects, this may be a no-op. Python automatically flushes files when they are closed. However, you may want to flush the data…
