Python Input function - number and string

Question

I am trying to get python to do the following

while tries:
   guess = input ("Guess no: " + 3-tries+ ": ")
   ....
   tries=tries-1

but I get the error message TypeError: Can't convert 'int' object to str implicitly. How can I successfully code this?

You cannot cast variable of type int to string implicitly. You have to use str() method.

For example:

>>> str(10)
'10'

So, you have to write:

input ("Guess no: " + str(3-tries) + ": ")

You can use python's string formatting to print an int in a string

guess = input ("Guess no: {}: ".format(3-tries))

Or, for python2.6

guess = input ("Guess no: {0}: ".format(3-tries))

Use input("Guess no: {0}".format(3-tries)) so that python2.6 would be happy, right?

yes, python 2.6 needs an index, python >2.7 doesn't require that
