Python TypeError: coercing to Unicode: need string or buffer, tuple found

Question

#!/usr/bin/env python
import sys
import os

print "Scan a file for ""ErrorScatter"" payload"
print "Drag the suspicious file here then press enter."
filepath = raw_input("File Location: ")
fixpath = filepath , "/Contents/MacOS/ErrorScatter"
scan = os.path.exists(fixpath)

So i am making a program to check if a file has a "ErrorScatter" payload but i keep coming across and error when testing my creation. Since i'm a newb i do not know how to fix this.

This is the error i'm getting:

TypeError: coercing to Unicode: need string or buffer, tuple found

Would anyone know how to fix this?

Answer 1

, operator in Python is used to create tuples, for example

1, 2, 3

makes 3-element tuple

(1, 2, 3)

and

"blah", "bleh"

means 2-element tuple

("blah", "bleh")

To concatenate strings, you could use + as Gaurav already suggested:

fixpath = filepath + "/Contents/MacOS/ErrorScatter"

but in fact the better way is to

import os

fixpath = os.path.join(filepath, "Contents/MacOS/ErrorScatter")

or even

fixpath = os.path.join(filepath, "Contents", "MacOS", "ErrorScatter")

(using os.path.join is a habit you will appreciate once you happen to run some scripts on windows, this one is not too likely but habits grow by repetition...)
