>>>print('{} is a {}'.format('dog','animal'))# {}为占位符,分别对应后面实际的值dog is a animal>>>print('{1} have a {0} time {2}'.format('good','mary','today'))# 在{}中添加序号,序号为n则对应后面第n个值(n从0开始)mary have a good time toda
字符串的内置方法包括:移除空白strip、切分split、长度len、切片(切出子字符串)、startswith和endswith、替代replace、查找find(顾头不顾尾,找不到则返回-1不报错)、index(顾头不顾尾,但找不到会报错)、count(顾头不顾尾,若不指定范围则查找所有)、格式化输出%或.format()、插入join、插入空格expandtabs、全大写up...
bytestring = b"This is a bytestring." string = bytestring.decode() print(string) Output This is a bytestring. Working with bytestring methods Bytestrings have a variety of methods that operate similarly to string methods. For instance, methods like startswith(), endswith(), and others ...
字符串是 Python 中最常用的数据类型。我们可以使用引号('或")来创建字符串 str() 例如:a=' ' 等于a=str('') 或者 a= "" a=str("") a="a b c d" print(a) 常见用法 索引 移除空白strip() 切分 split() 取长度len() endswith('xx') 以xx结尾 startswith('xx') 以xx开头 replace('a',...

What’s more, mangling raw strings in Python really isn’t a great way of dealing with HTML. There’s a much better solution, which is to use templates. Quite apart from anything else, if we can keep HTML to one side in a file whose name ends in .html, we’ll get better syntax ...

“MSE” represents the pixel-wise Mean Squared Error between the images, and “M” is the maximum possible value of a pixel in an image (for 8-bit RGB images, we are used to M=255). The higher the value of PSNR (in decibels/dB), the better the reconstruction quality. InPython3...
