A binary number is a number expressed in the base-2 numeral system or binary numeral system, which uses only two symbols 0 and 1.
The decimal numeral system is the standard system for denoting integer and non-integer numbers.
In this blog, we will create python programs for converting a binary number into decimal.
Pythonic way to convert binary into decimal
Enter a binary number, make it as a list and make the value of decimal number equals zero.
binary = list(input("please enter a binary number: ")) d_num = 0
Use a for loop to iterate over the length of our list .
Use the pop() method that returns the item present at the given index. This item is also removed from the list and assign its value to the digit variable.
Use the if statement to check whether the digit equals one or not . If it is true , the d_num will equal to the sum of itself and two raised to the i power .
for i in range(len(binary)): digit = binary.pop() if digit == '1': d_num = d_num + pow(2,i) print("The Decimal Number is ", d_num)
Finally, This is an example of the results
please enter a binary number: 111000 The Decimal Number is 56
