Which of the following code snippets is the correct one for opening the hello txt file for writing
Python provides inbuilt functions for creating, writing, and reading files. There are two types of files that can be handled in python, normal text files and binary files (written in binary language, 0s, and 1s). Show
In this article, we will be focusing on opening, closing, reading, and writing data in a text file. File Access Modes Access modes govern the type of operations possible in the opened file. It refers to how the file will be used once its opened. These modes also define the location of the File Handle in the file. File handle is like a cursor, which defines from where the data has to be read or written in the file. There are 6 access modes in python.
How Files are Loaded into Primary Memory There are two kinds of memory in a computer i.e. Primary and Secondary memory every file that you saved or anyone saved is on secondary memory cause any data in primary memory is deleted when the computer is powered off. So when you need to change any text file or just to work with them in python you need to load that file into primary memory. Python interacts with files loaded in primary memory or main memory through “file handlers” ( This is how your operating system gives access to python to interact with the file you opened by searching the file in its memory if found it returns a file handler and then you can work with the file ). Opening a File It is done using the open() function. No module is required to be imported for this function. File_object = open(r"File_Name","Access_Mode") The file should exist in the same directory as the python program file else, the full address of the file should be written in place of the filename. Note: The r is placed before the filename to prevent the characters in the filename string to be treated as special characters. For example, if there is \temp in the file address, then \t is treated as the tab character, and an error is raised of invalid address. The r makes the string raw, that is, it tells that the string is without any special characters. The r can be ignored if the file is in the same directory and the address is not being placed. Python

It is used at the time when the file is no longer needed or if it is to be opened in a different file mode.

Which of the following is correct to open a text file for write mode?w - opens or create a text file in write mode. a - opens a file in append mode. r+ - opens a file in both read and write mode.
Which of the following command is used to open a file data txt for reading?option 1 is correct answer
value opens a file in reading mode for text files. If you require writing to a text file, then use 'w' mode.
Which of the following can be used to open a file scores txt for reading in Python?The file should be opened for reading , so access_mode is “r” .
What is the correct way of opening a file for reading in Python?Opening Files in Python
Python has a built-in open() function to open a file. This function returns a file object, also called a handle, as it is used to read or modify the file accordingly. We can specify the mode while opening a file.
