(3). 浮点型(floating point values)浮点型构成由整数部分和小数部分构成 (4). 复数(complex numbers)复数由实数和虚数部分构成 可以使用 a+bj,或 compler(a,b) 表示,其中 a,b部分都是浮点型 注: 长整型的取值范围: python2.7版本中长整型的取值范围为-263-1次方至263次方 python3中没有long类型,使用int...

Python format number with commas Now, let me show you different methods to format numbers with commas in Python. 1. Using f-strings (Python 3.6+) F-strings, introduced in Python 3.6, provide one of the best ways to format strings, including numbers with commas. Here’s how you can use...

str.format()方法:这是一种更现代的字符串格式化方式,它使用大括号{}作为占位符,并支持更多的格式化选项,如对齐、精度和类型转换。 f-字符串:这是Python 3.6及更高版本引入的一种新的字符串格式化方式,它使用前缀f,允许在大括号{}内插入变量或表达式,非常直观和简洁。
