What string does the following produce: “a %d b %d” % (1,2) A.“a 1 b 2 d” B.“a b d 1 2” C.(results in error) D.“a %d b %d % (1,2)”
3
“a %d” % 1 The first % above (before the d) is called a “conversion specification,” which means that it explains how the 1 on the right should be “converted” when placing it in the string. How does Python know that this first above % does not mean modulo (remainder)? A.It comes before a d B.It is part of a string C.It is in a line with two % signs D.The python knows all and sees all
4
“a %d” % 1 The second % above (before the 1) is called a “formatting operator”, and indicates that the 1 should be appropriately inserted into the “format string” on the left. How does Python know that the second % means this, and not modulo (remainder)? A.The number to the right matches the conversion specifications in the string on the left B.It has a string to the left of it C.It is in a line with two % signs D.The python knows all and sees all
