convert_dtypes() pandas

• pandas 默认 读取文本数据时，会自动读成object。
• 通过convert_dtypes()可以自动读成最新支持的类型，string

dataframe = pd.read_csv('/home/mw/input/Soviet_70yrs4904/RUStoWorldTrade.csv',
usecols=['Year','Aggregate Level','Reporter ISO','Partner','Partner ISO','Commodity Code','Commodity','Qty Unit','Qty','Netweight (kg)','Trade Value (US$)'])
dataframe = dataframe.convert_dtypes()

数据预处理 📋

数据集庞大，包含130万个数据点，因此它具有 650mb的高内存使用率, 我们将使用作者提供的 Starter Code 代码来优化性能。它将把数据类型转换为更小的数据类型，并帮助我们从 五个聚合级别中选择一个 and 并将内存使用率降低95%

Aggregate Level	Level Name	Code Format	Number of Items
1	Section	0	10 Items
2	Division	01	67 Items
3	Group	012	261 Items
4	Subgroup	012.1	1033 Items
5	Item	012.13	3121 Items

info

• Dataframe对象调用info()会显示DataFrame的内存是哟航情况。
• memory_usage='deep’将启用更准确的内存使用报告，将更费内存。

通过memory_usage，查看各列内存使用量，然后就可以针对性进行内存优化了。

Pandas Profiling 📋

了解数据，使用交互式元素进行浏览 🔬

pandas df.describe() 函数 很强大，但对于严肃的探索性数据分析来说，这是一点基础。 pandas_profiling 用扩展pandad数据帧。profile_report()于快速数据分析。

top_countries_by_year = df[df['Year'].isin(year_list)]
top_countries_by_year = top_countries_by_year[top_countries_by_year['Trade Value (US$)'] >= 0]
top_countries_by_year = top_countries_by_year.groupby(['Year','Partner ISO']).agg({'Trade Value (US$)':'sum'}) ; top_countries_by_year.reset_index(inplace=True)
top_countries_by_year.sort_values(by=['Year','Trade Value (US$)'],ascending=[True,False], inplace=True)

II. 各大洲贸易出口细目 🗺️

我们可以得出结论，大多数出口都是与邻国或陆地范围内的国家进行的（运输方式不需要海运/空运方式）。世界银行的一项研究表明，全球90%的货物是通过海运运输的。
