Using a Variable in Python String

I'm not sure how to word the question, and I'm not finding anything in searches.

I have a variable, and want to pass it into f.open() as the name of the file to open. The goal is to type a file name into foo, then it clears the files.

foo = str(raw_input('enter a filename '))
bar = foo   
f = open('foo', 'w')
f.write("")
f.close()

I've tried using open(foo, 'w') and replacing it with 'bar', but neither seems to work. Any suggestions?

Remove the '' from 'foo':

f = open('foo', 'w')

Like this:

f = open(foo, 'w')

'foo' is a literal string and foo is a variable name that holds the file name the user entered.

f = open(bar, 'w')

Just pass the variable name (without quotes of course).

Additionally, you don't need the line bar = foo. You are already storing the filename as foo with your first line.

So... if you remove bar = foo it would be f = open(foo, 'w')
