Name error/is not defined

[foxtreat]

i just starter learning coding/programing,and after some joking around with bash i decided to learn python
i am making a script that should ask for your name and make a folder in the scripts directory using your name,however after imputing a name it just gives an error,
INFORMATION-i am using linux however i want my script to be cross-platform with windows aswell,python 3
here is my code

#!/usr/bin/env python
print "hello,i will automaticaly set up you account and files"
print "you will need to enter some data,be honest"
myname = input("What's your name?: ")
print (myname)
print "your name is" + (myname) 
print "okay,please wait while i set up your information"
import os 
os.mkdir((myname))
exit

i enter a name,lets say the name is da
i get this error

Error:
Traceback (most recent call last):
  File "python.py", line 4, in <module>
    myname = input("What's your name?: ")
  File "<string>", line 1, in <module>
NameError: name 'da' is not defined

i have tried alot of threads but nothing has worked
how do i make this error go away?
