pleae help how to start coding to concantenate strings that contains numbers and string

Do you want to know how to concatenate a string and an integer using +? If so: by converting the integer to a string first. That might look like this:

x = 42
foo42 = s + str(x)

That said using format might be better than using + here:

"foo{}".format(x)
