percentage = f"{value:.2f}%" # format the value to a string with 2 decimal places and append a "%" sign print(percentage) # output: 50.00% 在Python中，我们可以使用多种方法来输出百分比。最常用的方法是使用print()函数和格式化字符串。从Python 3.6开始，推荐使用f-strings(格式化字符串字面量)，因为它提供了更简洁的语法。
>>> num = 4.123956>>> f"num rounded to 2 decimal places = {num:.2f}"'num rounded to 2 decimal places = 4.12'如果不做任何指定，那么浮点数用最大精度 >>> print(f'{num}')4.123956 格式化百分比数 >>> total = 87>>> true_pos = 34>>> perc = true_pos / total>>> perc0.390...
1 首先在PyCharm软件中，打开一个Python项目。2 在Python项目中，新建并打开一个空白的python文件（比如：test.py）。3 在python文件编辑区中，输入：“import decimal”，导入 decimal 模块。4 接着输入：“TWOPLACES = decimal.Decimal(10) ** -2”，点击Enter键。5 使用 def 关键字定义一个 div 函数，函数...
In the example below, f indicates the value as a floating-point number while .2 specifies the decimal places to round the number. # Example number to be rounded number = 3.14159 # Using the % operator to round to 2 decimal places formatted_number = "%.2f" % number print(formatted_numbe...
