1.先替换为? 2.然后删除 data = data.replace(to_replace = "?", value = np.nan) data.dropna(inplace = True) 1. 2. 替换空值? 为nan 然后删除nan值 data.isnull().any() 1. 检查结果 出现全部为false的话为删除成功
Replace nan with zero and inf with large finite numbers. Ifxis inexact, NaN is replaced by zero,and infinity and -infinity replaced by the respectively largest and most negative finite floating point values representable by x.dtype. For complex dtypes, the above is applied to each of the real...

Suppose that we are given a NumPy array that contains some NaN values and we need to replace these NaN values with the closest numerical value (non-NaN values).How to replace NaN's in NumPy array with closest non-NaN value?To replace NaN's in NumPy array with closest non-NaN value, ...
Write a NumPy program to replace all the nan (missing values) of a given array with the mean of another array. Sample Solution:Python Code:# Importing the NumPy library import numpy as np # Creating NumPy arrays: array_nums1 from 0 to 19 reshaped into a 4x5 array and array_nums2 ...

savez()第一个参数是文件名,其后的参数都是需要保存的数组,也可以使用关键字参数为数组起一个名字,非关键字参数传递的数组会自动起名为arr_0, arr_1, …。 savez()输出的是一个压缩文件(扩展名为npz),其中每个文件都是一个save()保存的npy文件,文件名对应于数组名。load()自动识别npz文件,并且返回一个类似...
