![]() ![]() Creates a new file if it does not exist or truncates the file if it exists. On the other hand, binary mode returns bytes and this is the mode to be used when dealing with non-text files like images or executable files. In this mode, we get strings when reading from the file. We can also specify if we want to open the file in text mode or binary mode. In mode, we specify whether we want to read r, write w or append a to the file. ![]() We can specify the mode while opening a file. > f = open("C:/Python38/README.txt") # specifying full path > f = open("test.txt") # open file in current directory This function returns a file object, also called a handle, as it is used to read or modify the file accordingly. Python has a built-in open() function to open a file. Hence, in Python, a file operation takes place in the following order: When we are done, it needs to be closed so that the resources that are tied with the file are freed. When we want to read from or write to a file, we need to open it first. Since Random Access Memory (RAM) is volatile (which loses its data when the computer is turned off), we use files for future use of the data by permanently storing them. They are used to permanently store data in a non-volatile memory (e.g. Files are named locations on disk to store related information. ![]()
