如果是NaN,则打印出"x is NaN";否则,打印出"x is not NaN"。 在第二个示例中,我们创建了一个包含NaN值的DataFrame,并使用isna函数检查DataFrame中是否存在NaN值。如果存在NaN值,则打印出"DataFrame contains NaN values";否则,打印出"DataFrame does not contain NaN values"。 处理NaN值 当我们在数据分析和处...

You can not rely on thefloat()function to check whether a string is a float or not, however, it is a good fit to convert string values to float. 3. Use decimal Module to Check if a String is a Flaot Value Thedecimalmodule in Python provides high-precision decimal arithmetic, it can...
