AttributeError: 'str' object has no attribute 'string'

Question

I am getting the error:

AttributeError: 'str' object has no attribute 'string'

So here is the code:

lnumber=input("please type in numbers:")
lnumber.string().sort()
print(lnumber)

What I'm trying to do is:

user inputs numbers (e.g.: '2 1 4 3'); and
the code puts the numbers in ascending order.

input returns a str object, which doesn't have a string method - what were you expecting to happen? For the list of methods that str objects do have, see: docs.python.org/2/library/stdtypes.html#string-methods — jonrsharpe

@grc apologies, wrong link (see docs.python.org/3/library/stdtypes.html#string-methods); still no str.string, though. — jonrsharpe

what that weird string() applied to a string should do? maybe (if string is consistent) lst = [int(x) for x in lnumber.split(' ')];lst.sort() — cox

If the user is inputting numbers in that way then you probably want to use raw_input. After that you can use .split() to get a list of the numbers and then use .sort().

Example:

myRawInput = raw_input("Enter some numbers separated by spaces")
myList = myRawInput.split()
myList.sort()
