We have to multiply each value with 2 to raise to the power of values start from 0 to n.Īnd add all the values - (1*2^3)+ (1*2^2)+(0*2^1)+ (0*2^0)

Let’s consider a binary number – 1100 The decimal conversion process is How to Convert Binary to Decimal in Python

Method 5: Convert Binary string List to Decimal.

Method 4: Convert Binary List to Decimal.

Method 3: Convert Binary to Decimal using Recursion.Method 2: Convert Binary to Decimal without using the inbuilt function.Method 1: Convert Binary to Decimal using int().How to Convert Binary to Decimal in Python.Hope this tutorial helps you to understand how to convert binary to decimal in Python. You can see the output for some sample input of binary numbers.

Here we have created a function binary_to_decimal(binary) which takes the binary number as an argument and then convert the number to its equivalent decimal number. Here, using loops we iterate through the binary number which means through each digit which further yields into a decimal number, and now let’s see its execution. Output:: 5 Using For Loop – Binary to decimal Now let’s look into the code binary = '101' If x is not a number or if the base is given, then x must be a string, bytes, or byte-array instance which represent an integer literal in the given base. It returns 0 when the function receives no argument. Python uses inbuilt function int() which converts a number or string to an integer. Using in-built function – Convert Binary to Decimal Here we will discuss 2 ways in which we can do it. In this tutorial, we will learn how to convert binary numbers to decimal in Python.
