Writing to a File Python Tutorial



Welcome to another Python 3 basics tutorial. In this tutorial we're going to cover the basics of writing to a file.

It should be noted that there are two methods for saving data to a file, and those are writing and appending. Writing to a file will write that bit of data, whatever it is, solely, to the file. This means if there was anything there before, it will be gone if you use write.

If you use append, then you will basically add to whatever is previously there. I will be showing both methods, but write first.

text = 'Sample Text to Save\nNew line!'

# notifies Python that you are opening this file, with the intention to write
saveFile = open('exampleFile.txt','w')

# actually writes the information
saveFile.write(text)

# It is important to remember to actually close the file, otherwise it will
# hang for a while and could cause problems in your script
saveFile.close()

Saving data to a file is as simple as that! Just don't forget to close it or you will likely find yourself having lots of i/o issues in your programs!
