In Pandas, you can convert a Series to a dictionary using the to_dict() method. This method creates a dictionary where the index labels of the Series become the keys, and the corresponding values become the values in the dictionary.
# convert to dictionarysr.to_dict() 输出: 正如我们在输出中看到的,Series.to_dict()函数已成功将给定的系列对象转换为字典。 范例2:采用Series.to_dict()函数将给定的系列对象转换为字典。 # importing pandas as pdimportpandasaspd# Creating the Seriessr = pd.Series([19.5,16.8,22.78,20.124,18.1002])...
