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:

|Option|Meaning|
|---|---|
|`: ` (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,

```
Input
print(".{:+}.{: }.".format(3, -7))
print(".{:+}.{: }.".format(-6, 2)

Output
.+3.-7.
.-6. 2.
```

In this section you will be introduced with the basic concepts of strings in Python, such as creating, indexing, and slicing.

In this section we will learn important strings methods, like .split, .count, .strip and so on...
