Lecture 77:-  Decimal to Binary In Python

 

You can convert a decimal number to its binary representation in Python using the built-in bin() function. The bin() function takes an integer as an argument and returns its binary representation as a string prefixed with '0b'.

 

Here's an example of how to convert a decimal number to binary:

pythonCopy code

decimal_number = 25 binary_representation = bin(decimal_number) print(binary_representation)  # Output: '0b11001'

In this example, the decimal number 25 is converted to its binary representation, which is '0b11001'. The prefix '0b' indicates that the string represents a binary number.

If you want to remove the '0b' prefix and get the binary representation as a plain string, you can use string slicing:

pythonCopy code

decimal_number = 25 binary_representation = bin(decimal_number)[2:] print(binary_representation)  # Output: '11001'

Now, the binary representation is '11001' without the '0b' prefix.

Keep in mind that the binary representation is a string, so if you want to perform arithmetic or other operations with the binary value, you may need to convert it back to an integer using the int() function with base 2:

pythonCopy code

binary_representation = '11001' decimal_number = int(binary_representation, 2) print(decimal_number)  # Output: 25

In this case, the string '11001' is converted back to an integer with base 2, giving us the original decimal number 25.
