Advanced Formatting: SignAdvanced Formatting: Sign

Let's now consider the formatting of integer objects. Assume we want to represent our numbers along with plus/minus sign. The minus sign will be printed anyway, but plus sign never prints with an integer.

To make Python print a sign of a number we need to set sign option. There are three of them:

: (space after the colon)Use a space before positive number, a minus - before negative
:-Use a minus sign for negative numbers only
:+Use a plus sign for positive numbers, and minus - for negative

For example,


Given two variables: min_temp with value -40 and max_temp with value 42. You need to insert correct format options to display - sign for min_temp, and + sign for max_temp, and format string with these variables.

Everything was clear?
