what does this line explaining the Zen of Python mean?

I mean the part after the greater than signs: Explicit is better than implicit: It is best to spell out exactly what your code is doing. This is why >>>>>>>> adding a numeric string to an integer requires explicit conversion, rather than having it happen behind the scenes, as it does in other languages.

Sometimes you must specifically tell the python interpreter that a string is a string, and an int is an int. print(str(807) + "abc") gives the output 807abc, or print("807" + "abc") yields the same. Where int is used with a string, it goes like this: print(int("807") + 3) would have the output 810, and print( "807" + 3) would not have been told string "807" is an int like 807. So that would be a TypeError between adding just "807" + 3, which is a string plus an int. In another language you might mix the two but with type errors if the string isn't an int. Remember you can use the type function too: print(type("807")) print(type(807)) print(type(int("807"))) print(type(str(807)))

Run a Python program with the only line being "4"+2 and hopefully you will understand. If not comment here and I will explain.
