file is a built-in type and

file.write(file1)

is roughly equivalent to

file1.write()

The latter is the preferred way to invoke the method; thus the (confusing) 
error message

> TypeError: function takes exactly 1 argument (0 given)

is trying to convey that you are not providing any data to write. The 
correct call instead of

> file.write(file1)

is then

file1.write(file_data)
