系列數超過一定數量

Question

鑑於這種代碼在IPython中

df1=df["BillingContactCountry"].value_counts() 
df1 

大我得到

United States      4138 
Germany       1963 
United Kingdom      732 
Switzerland       528 
Australia       459 
Canada        369 
Japan        344 
France        303 
Netherlands       285 

我想用數比303大的系列，我該怎麼辦？

Answer 1

您需要boolean indexing：

print (df1[df1 > 303]) 
United States  4138 
Germany   1963 
United Kingdom  732 
Switzerland  528 
Australia   459 
Canada    369 
Japan    344
