Arcpy.Buffer_Analysis Does Not Create Feature Class

import arcpy

arcpy.env.workspace = r'c:\data'

fcs = str(raw_input('Please enter the layers you would like to buffer: '))

dist = str(raw_input('What would you like your buffer distance to be? '))

output = str(raw_input('Name your output: '))


for fc in fcs:
    if arcpy.Exists(fcs):
    arcpy.Buffer_analysis(inputs, output, dist)
if not arcpy.Exists(fcs):
    print "Feature class does not exist"

The above script executes but does not create the feature class I want. Where am I going wrong?
