Are python files text files?
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
Here, file1 is created as an object for MyFile1 and file2 as object for MyFile2 Closing a file close() function closes the file and frees the memory space acquired by that file. 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. File_object.close() Python
Writing to a file There are two ways to write in a file.
File_object.write(str1)
File_object.writelines(L) for L = [str1, str2, str3] Reading from a file There are three ways to read data from a text file.
File_object.read([n])
File_object.readline([n])
File_object.readlines() Note: ‘\n’ is treated as a special character of two bytes Python3
Output: Output of Read function is Hello This is Delhi This is Paris This is London Output of Readline function is Hello Output of Read(9) function is Hello Th Output of Readline(9) function is Hello Output of Readlines function is ['Hello \n', 'This is Delhi \n', 'This is Paris \n', 'This is London \n'] Appending to a file Python3
Output: Output of Readlines after appending ['This is Delhi \n', 'This is Paris \n', 'This is London \n', 'Today \n'] Output of Readlines after writing ['Tomorrow \n']

Are .PY files text files?A PY file is a program file or script written in Python, an interpreted object-oriented programming language. It can be created and edited with a text editor, but requires a Python interpreter to run. PY files are often used to program web servers and other administrative computer systems.
Are Python files binary or text?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).
What type of file is Python?The Files with the . py extension contain the Python source code. The Python language has become very famous language now a days. It can be used for system scripting, web and software development and mathematics.
Can Python write to a text file?In Python, you can write to a text file by following these three steps: Open a file using the open() function. Write to the file using the write() method.. Close the file using the close() method.
