bin()Convert Int to Binary in Python using
In Python, you can use the built-in function bin()to convert an integer to binary. bin()The function takes an integer as an argument and returns its 0bbinary string equivalent prefixed with .
Here is an example.

0b10000
formatConvert Int to Binary in Python using
As shown above, the binary representation of an integer can bin(x)be easily obtained using the method. However, if you want to remove 0bthe prefix from its output, you can use formatthe function to format the output.
format(value, format_spec)The function takes two parameters - valueand format_spec. It will format_specreturn the formatted output according to . Here are some examples of the type of formatting that can be used in placeholders.

Following is str.format()the sample code to convert int to binary using method.
temp = "{0:b}".format(15)
