import pandas as pd df = pd.DataFrame({'Id':['a','b']}) X = df.Idprint([i in X for i in X]) resulting in printing '[False, False]'. The correct thing to do was using "X = df.Id.tolist()", but it still seems a bit odd that the above code doesn't return an array...
方法一:iterrows(逐行迭代) iterrows() 方法可以按行迭代DataFrame。该方法返回两个值,分别是行索引和行数据,我们可以通过解包操作来获取它们。然后我们可以使用for循环来遍历每一行数据。 示例: importpandasaspd# 创建数据data={"Name":["Tom","Jerry","Peter"],"Age":[23,25,27],"Gender":["Male","Femal...
