How to use the bin function in Python

In Python, the bin() function is used to convert an integer into a binary string. Its syntax is as follows:

bin(x)

The function converts an integer x into binary and returns a string starting with “0b” followed by the binary representation of x.

Here are some examples:

bin(10)  # '0b1010'
bin(15)  # '0b1111'
bin(7)   # '0b111'

Please note that the returned binary string is a string with the prefix “0b”. If you do not want this prefix, you can remove it using slicing operations.

bin(10)[2:]  # '1010'
bin(15)[2:]  # '1111'

In addition, the bin() function can also be used to convert other types of data into binary strings, such as converting letters into their binary representation of ASCII codes.

bin(ord('A'))  # '0b1000001'
bin(ord('B'))  # '0b1000010'
