num = 100print("The decimal number is: {:d}".format(num))print("The binary number is: {:b}".format(num))print("The hexadecimal number is: {:x}".format(num))输出结果为：The decimal number is: 100The binary number is: 1100100The hexadecimal number is: 64 时间格式化，在时间处理中，...
Example: Number Formatting With Precision Precision allows us to define the number of digits to be shown after a decimal point. For example, # set precision to 2 for floating-point numberprecision_value = format(123.4567,'.2f') print(precision_value)# Output: 123.46 Run Code Here,.2fmeans ...
示例4：使用格式化占位符和格式化选项：pi = 3.141592653589793 formatted_string = "Pi is approximately {:.2f} or {:.5f} decimal places.".format(pi, pi) print(formatted_string) # 输出：Pi is approximately 3.14 or 3.14159 decimal places.注意事项 在使用format函数时，有一些技巧和注意事项可...
以一个数字或关键字 arg_name 打头,如果为数字,则它指向一个位置参数,而如果为关键字,则它指向一个命名关键字参数; “conversion”字段在格式化之前进行类型强制转换,目前支持的转换旗标有三种: ‘!s’ 会对值调用 str(),’!r’ 调用 repr() 而‘!a’ 则调用 ascii(); format_spec 字段包含值应如何呈现...
Testing Round-Half-Even (Banker's rounding) A '5' is rounded to the closest 'even' number """self.assertEqual(numbers.format_decimal(5.5,'0', locale='sv'),'6') self.assertEqual(numbers.format_decimal(6.5,'0', locale='sv'),'6') ...
Again similar to truncating strings the precision for floating point numbers limits the number of positions after the decimal point. For floating points the padding value represents the length of the complete output. In the example below we want our output to have at least 6 characters with 2 ...

format函数用法python format函数用法stata 使用加号(+)操作符和转换函数(如IntToStr),你确实能把已有值组合成字符串,不过另有一种方法能格式化数字、货币值和其他字符串,这就是功能强大的Format 函数及其一族。 Format 函数参数包括:一个基本文本字符串、一些占位符(通常由%符号标出)和一个数值数组,数组中每个值...
