Return Values
The bin() function returns a string in the format '0bxxx', where 'xxx' is the binary representation.
How to Use bin() in Python
Example 1:
The bin() function converts an integer number to a binary string prefixed with '0b'.
number = 10
binary_string = bin(number)
print(binary_string)
Example 2:
The bin() function works with negative integers as well, using two's complement representation.
number = -5
binary_string = bin(number)
print(binary_string)
Example 3:
You can use bin() in conjunction with string formatting to get a specific binary representation format.
number = 42
formatted_binary = '{:08b}'.format(number)
print(formatted_binary)
