I want the Call column to always have 4 decimal places and X and Y to always have 3. Originally, I would use the float_format argument in to_csv, but that only appears applicable if all floats are treated the same way. How would I go about specifying the number of digits...
# It sets the precision of the decimal module to 10. getcontext().prec =10 # Converting the integer 9 to a string and then converting it to a Decimal object. decimal_ = Decimal(1) / Decimal(str(9)) print('向下取整保留10位小数:{0}'.format(decimal_.quantize(Decimal('0.0000000000'))...

format()函数是Python中常用的字符串格式化方法,可以用来格式化数字。使用方法如下: x = 123.456 print("Formatted number with 2 decimal places: {:.2f}".format(x)) 这里,{:.2f}表示输出浮点数保留2位小数,输出结果为123.46。 更多使用方法: {}:默认的字符串格式化 {:<}:左对齐 {:^}:居中对齐 {:<...

defround_to_two_decimal_places(number):return'{:.2f}'.format(number) 1. 2. 以上代码定义了一个名为round_to_two_decimal_places的函数,它接受一个数字作为输入,并返回保留两位有效数字并自动补0的结果。 示例 假设我们有一个数值列表[0.123, 1.234, 12.345, 123.456, 1234.567],我们希望将每个数值保留两...
