Remove Nan Values Using theisfinite()Method in NumPy As the name suggests, theisfinite()function is a boolean function that checks whether an element is finite or not. It can also check for finite values in an array and returns a boolean array for the same. The boolean array will store...
步骤1:创建一个包含NaN元素的列表 首先,我们需要创建一个包含NaN元素的列表。在Python中,可以使用numpy库来创建NaN元素。以下是创建包含NaN元素的列表的示例代码: importnumpyasnp# 使用numpy库创建包含NaN元素的列表my_list=[1,2,np.nan,3,np.nan,4] 1. 2. 3. 4. 在上述示例代码中,我们使用numpy库的nan...

x: This is the value or array you want to check for NaN. It can be a single numeric value, a NumPy array, or a list of values. The numpy.isnan() function returns True for NaN values and False for non-NaN values. If you apply it to an array or list, it returns a Boolean arr...
