format用法 相对基本格式化输出采用‘%’的方法,format()功能更强大,该函数把字符串当成一个模板,通过传入的参数进行格式化,并且使用大括号‘{}’作为特殊字符代替‘%’ 使用方法由两种:b.format(a)和format(a,b)。 1、基本用法 (1)不带编号,即“{}”(2)带数
>>> '{0}{1}{0}'.format('abra', 'cad') # 可重复 'abracadabra' 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 通过名字匹配参数 1. >>> 'Coordinates: {latitude}, {longitude}'.format(latitude='37.24N', longitude='-115.81W') ...
"0x" + format(e,"x").zfill(2) for e in data]print(as_hex)输出：['0x00', '0x01']

format替换「%」说明:This PEP proposes a new system for built-in string formatting operations, intended as a replacement for the existing ‘%’ string formatting operator. No.1 万恶的加号 Python中的字符串在C语言中体现为是一个字符数组,每次创建字符串时候需要在内存中开辟一块连续的空,并且一旦需要修...
