Python Octal is a base $8$ numbering system, which essentially means it counts in eights. Many computing systems use octal as it is often convenient for working with binary data $($as there are $8-$bits in a byte$).$ There is a simple recipe we can use to convert any octal number to decimal:

$1.$ Find the number of digits in the octal number.

$2.$ Suppose the octal number has $\backslash ($ n $\backslash )$ digits. Each digit in the number has a position. The right$-$most digit $($least significant digit$)$ in the number is at position $1,$ and the left most digit $($most significant digit$)$ at position $\backslash ($ n $\backslash ).$

$3.$ Multiply each digit with $\backslash (8^\{$p$-1\}\backslash ),$ where $\backslash ($ p $\backslash )$ is its position in the number.

$4.$ Add all the individual results from this multiplication process.

$5.$ The result will be the decimal equivalent of the given octal number.
