Reading files is cool and all, but writing to files is a whole lot more fun. It also should instill a sense of danger in you because you can overwrite content and lose everything in just a moment. Despite the threat of danger, we press on. Python makes writing to files very simple. With somewhat similar methods to reading, writing has primarily 2 methods for writing. If presented with a list of file names — beautify_bash.py file1.sh file2.sh file3.sh — for each file name, it will create a backup (i.e. file1.sh~) and overwrite the original file with a beautified replacement. If given '-' as a command-line argument, it will use stdin as its source and stdout as its sink: script (string) - the name of an available Blender Text (use Text.Get() to get a complete list) or the full pathname to a Python script file in the system. Note: the script is executed in its own context -- with its own global dictionary -- as if it had been executed from the Text Editor or chosen from a menu. Exchange online protection for on premiseWriting files is a lot like reading from them. In day-to-day consumer-friendly computing, we're usually given a few warnings to prevent accidents in which we overwrite existing files, e.g. "Are you sure you want to permanently erase the items in the Trash?". Python does not do that, which means we have to be extra careful when writing files..

Using the with pattern, we safely open the file and let Python close it for us. To read a file one line at a time, use a for loop. That's it. Besides having explicit methods like read(), the stream object is also an iterator which spits out a single line every time we ask for a value.
Writing to Files in Python. In order to write into a file in Python, we need to open it in write w, append a or exclusive creation x mode. We need to be careful with the w mode, as it will overwrite into the file if it already exists. Due to this, all the previous data are erased. Text files: In this type of file, Each line of text is terminated with a special character called EOL (End of Line), which is the new line character ('\n') in python by default. Binary files: In this type of file, there is no terminator for a line and the data is stored after converting it into machine-understandable binary language.
