Converting Integers to Binary Strings in Python

When dealing with binary data in Python, it is often necessary to convert integers into binary strings. This conversion can be easily achieved using Python's string format method.

How to Convert an Integer to Binary String

The string format method takes a format specifier as an argument. To convert an integer to a binary string, use the following format spec:

"{0:b}"

For example, to convert the integer 37 to a binary string:

>>> "{0:b}".format(37)
'100101'

Explanation

The format specifier "{0:b}" uses:

• 0: The index of the argument to format (in this case, the integer 37).
• b: The format specifier for binary conversion.

Note:

Python 2 and Python 3 have slightly different string format syntax. Visit the provided documentation links for more information on format specs in your specific Python version.
