To write content to a file, first you need to open it using the open() global function, which accepts 2 parameters: the file path, and the mode.
You can use a as the mode, to tell Python to open the file in append mode and add content to the file
filename = '/Users/flavio/test.txt'
file = open(filename, 'a')
#or
file = open(filename, mode='a')Or you can use the w flag to clear the existing content:
filename = '/Users/flavio/test.txt'
file = open(filename, 'w')
#or
file = open(filename, mode='w')Once you have the file open, you can use the write() and writelines() methods.
write() accepts a string.
writelines() accepts a list of strings:
filename = '/Users/flavio/test.txt'
file = open(filename, 'w')
file.write('This is a line\n')
file.writelines(['One\n', 'Two'])
file.close()
\nis a special character used to go to a new line
Remember to close a file after writing to it, using the file’s close() method.
