Python Open a txt file without clearing everything in it?

Question

file = io.open(\'spam.txt\', \'w\')
file.write(u\'Spam and eggs!\\n\')
file.close()

....(Somewhere else in the code)

file = io.open(\'spam.txt\', \'w\')
file.write         


        

Answer 1

You need to open it in append mode

file = io.open('spam.txt', 'a')

Answer 2

Change 'w' to 'a', for append mode. But you really ought to just keep the file open and write to it when you need it. If you are repeating yourself, use the logging module.

Answer 3

file = io.open('spam.txt', 'a')

Use mode 'a' for Append.

Answer 4

file = io.open('spam.txt', 'a') 
file.write(u'Spam and eggs!\n') 
file.close()

The w(rite) mode truncates a file, the a(ppend) mode adds to current content.
