The power of the Python language lies in its rich set of built-in functions, one of which isbin()Function. This article will dive in**bin()The usage of the function, the function and application scenarios are introduced step by step, and the reader can understand the function of the function more comprehensively by citing relevant books.
In Python,bin()Functions are used to convert integers to binary strings. Its basic syntax is as follows:
pythoncopy codebin(x)Among them,
xis an integer that needs to be converted.
The most basic usage is to convert an integer to its binary representation:
pythoncopy codenum = 10binary representation = bin(num)print(binary representation) output:'0b1010'Sometimes we may need to unprefix the binary string
'0b', which can be achieved by slicing the operation:
pythoncopy codebinary str = bin(15)[2:]print(binary str) output:'1111'
bin()Functions are especially handy for bit manipulation. For example, see how many bits in the binary representation of an integer are 1:
pythoncopy codenum = 27binary_str = bin(num)[2:]count_of_ones = binary_str.count('1')print(count of ones) output: 4bin()Functions can also be used to convert binary strings back to integers:
pythoncopy codebinary_str = '1101'decimal num = int(binary str, 2)print(decimal num) Output: 13Python Core Programming(Written by Wesley J.)chun): The book details the use of Python's built-in functions, which is essential for an in-depth understanding
bin()Functions are helpful.
《python cookbook》(Written by D**ID Beazley, Brian K.)Jones): The book contains a wealth of Python programming skills, forbin()The advanced use of functions provides some useful examples.
bin()Functions have a unique advantage when it comes to working with binary data and performing bit manipulations, and by understanding their usage, we can be more flexible in handling binary representations of integers. Hopefully, this article will help readers better understand and applybin()functions, making it one of the indispensable tools in Python programming.
