Use + to join strings together: python first = "Hello" second = "World" result = first + " " + second # "Hello World" Notice we added a space string in between. Without it, you'd get "HelloWorld".
You can only concatenate strings with strings. "Age: " + 25 causes an error. Convert the number first: "Age: " + str(25) works. For joining many strings, consider join() or f-strings (covered soon). Concatenation with + is fine for a few pieces but gets messy with many.
