However, you want to generate an output up to two decimal places, i.e., Area = 78.54 Hence, without further delay, let us dive into the solutions to our problem. 💡 Method 1: Using String Formatting Python majorly has 3 ways of formatting a string. These are – str.format() f...
这里我们调用了float_to_two_decimal_places函数并传入了3.1415926作为参数,然后打印函数的返回值。运行上述代码,我们将得到保留两位小数的结果3.14。 五、总结 通过本文我们学习了如何使用Python实现一个保留两位小数的函数。首先,我们通过将浮点数转换为字符串来进行处理,然后使用字符串的format方法将浮点数保留两位小数。...
The colon (:) tells our code we want to format a value. The zero is used to make Python aware that we’re dealing with a number that may be padded with zeros. The .2 instructs Python to round our number to two decimal places. The “f” shows our value as a number. Let’s run...
