data_new['dates'] = pd.to_datetime(data_new.dates) # Convert to dateNext, we can apply the sort_values function to order our pandas DataFrame according to our date variable:data_new = data_new.sort_values(by = [
首先,让我们看看如何创建一个GroupBy对象: importpandasaspd# 创建示例数据data={'name':['Alice','Bob','Charlie','Alice','Bob'],'city':['New York','London','Paris','New York','London'],'sales':[100,200,300,400,500]}df=pd.DataFrame(data)# 按name列进行分组grouped=df.groupby('name')...
print(sorted_arr) # 输出: [1, 2, 3] 而对于pandas DataFrame ,使用.sort_values()方法可以灵活地根据列进行排序: import pandas as pd data = {'Name': ['Alice', 'Bob', 'Charlie'], 'Age': [24, 30, 19]} df = pd.DataFrame(data) sorted_df = df.sort_values(by='Age') print(sorte...
