can only concatenate str (not “int”) to str

# To solve the issue, just add str to your number or value like:

print( "Alireza" + str(1980))

Here is what the above code is Doing:
1. It’s converting the number 1980 to a string.
2. It’s concatenating the string “Alireza” with the string “1980”.
3. It’s printing the result.
