I appreciate your desire to study👏 if you are here it means you are motivated a lot.

The last push of studying numeral systems is learning the format method for strings to convert numbers to different numeral systems.

`format()` allows you to do the complex substitution, but it goes beyond this course; hence, here you are going to get acquainted with converting numbers using this method. By the way, it is an opportunity for you to pick up the one that you prefer.

This example shows you how decimal numbers can be converted to other numeral systems.

# Сonverting to the binary numeral system
"{:b}".format(9873)
# Сonverting to the octal numeral system
"{:o}".format(9873)
# Сonverting to the hexadecimal numeral system
"{:X}".format(9873)

`{:b}` is used to define the binary numeral system.

`{:o}` or `{:O}` (both ways are acceptable) is used to define the octal numeral system.

`{:X}`(the hexadecimal number must be defined using uppercase letters) or `{:x}`(the hexadecimal number must be defined using lowercase letters) is used to define the hexadecimal numeral system.

Subsequently, you should use the following syntax:    `{:numeral_system_format}.format argument)`
This method has a significant benefit it prints your number without `0b`, `0o`, `0x`, only converted number.
But unfortunately to convert not decimal numbers you should write `0b`, `0o` or `0X`. The decimal converting is diverse you can use 3 methods😃: `{}`,`{:n}` or `{:d}`

# Сonverting from the binary numeral system to decimal
"{}".format(0b11011)
# Сonverting from the octal numeral system to decimal
"{:n}".format(0o3443)
# Сonverting from the hexadecimal numeral system to decimal
"{:d}".format(0X67AB)

Have you seen such code 110101 before? It refers to the binary numeral system and is considered to be the most commonly used one. Here you are going to learn the main concepts of converting

This section is going to help you get acquainted with one less commonly used but vitally important numeral system.

The last numeral system for you and maybe the most complex one, but it is still a superior chance for practicing.

Here you are going to dive deeper into some of the built-in python functions. This section is going to make you get familiar with converting to different numeral systems without any loops and conditions, just python functions
