How to append an integer to a string

Question

I have an integer and I have a string. Now I want to create a new string which is got by concatenated the string and the integer. But I don’t understand how to do this?

I am using this following code:

a = 10

new = “hello” + a

But I get this error:

File "program.py", line 2,

new = “hello” + a

TypeError: Can't convert 'int' object to str implicitly

You can not directly concatenate two different data-types. You have to type-cast it first.

Try this code:

name = 'b' + str(num)

or

name = 'b%s' % num
