In Python two, mixing Unicode and eight-little bit information would get the job done If your string took place to incorporate only 7-bit (ASCII) bytes, but you should get UnicodeDecodeError if it contained non-ASCII values. Also, the exception would materialize at the combination point, not at The purpose at which the non-ASCII characters were put to the str object. This habits was a typical source of confusion and consternation for neophyte Python programmers.
Though both equally solutions look at the beginning blush to provide the identical result, You can find an extremely considerable difference between The 2. Approach two makes, as you should count on, an variety of 3 elements, each of which happens to be alone an independent 4-factor array.

When the default worth for just a function argument is definitely an expression, the expression is evaluated only once, not each and every time the operate is called. Thus, when the checklist argument has actually been initialized to an empty array, subsequent phone calls to append with no argument specified will continue on to make use of precisely the same array to which list was at first initialized. This could thus yield the subsequent, presumably unpredicted, habits:
I hired him quickly and he squandered no time in hire coders attending to my venture, even heading the additional mile by introducing some fantastic design aspects that enhanced our Over-all appear.
